[Water supply method of water supply device]
Here, the water supply system of the water supply device 10 in this embodiment will be explained using FIGS. 2 and 3. In both the examples shown in FIGS. 2 and 3, a monitoring device 210 is provided in a monitoring room 200 within a building 170. In addition, in this embodiment, the water supply method shown below can be changed by the control parameter of the water supply apparatus 10.

FIG. 2 is a diagram showing an example in which the water supply system of the water supply device 10 is a water tank system. In the example shown in FIG. 2, the water supply device 10 is used as a single water tank type in which one water tank 160 is connected to the suction side (primary side). However, the water supply device 10 may have two or more water tanks connected to the primary side. The water receiving tank 160, which is a water supply source, and the suction port 10A of the water supply device 10 communicate with each other through an introduction pipe 171. In the water tank system, the water supply device 10 uses a pump to pressurize water stored in a water tank 160 from a water supply main, which is a water supply source (not shown), and supplies water to each water tap 172 in the building 170.

The water tank 160 is provided with a water level gauge, specifically an electrode level switch 162, for detecting the water level in the water tank 160. In this embodiment, when the water level in the water receiving tank 160 is below the reduced water level, which is higher than the drought water level at which the pump is forcibly stopped, the "water reduction state" is reached, and when the water level becomes even lower, a predetermined state is reached at which the pump is forcibly stopped. When the water level falls below the water level (drought water level), a "drought state" occurs. Furthermore, when the water level reaches a predetermined level (full water level) at which there is a risk of water overflowing from the water tank 160, the water tank 160 becomes "full of water". Note that the control unit 65 has a set value for determining whether or not to detect a water decrease, and if the control unit 65 does not detect a water decrease, if the water level of the aquarium is higher than the drought water level and less than the full water level, the water level information is is the "normal state". On the other hand, when the control unit 65 detects water reduction, if the water level of the aquarium is greater than or equal to the reduced water level and less than the full water level, the water level information is in a "normal state."

The detection signal from the electrode level switch 162 is input to the control section 65 (I/O section 70) of the water supply device 10, the details of which will be described later. The electrode level switch 162 includes, for example, a plurality of electrode rods 162a to 162e arranged within the water receiving tank 160. Each of the plurality of electrode rods 162a to 162e is a water level detector, and includes a common electrode rod 162a, an electrode rod 162b for detecting a drought water level, and a city water inflow valve 163 in order of ability to detect a low water level. An electrode rod 162c for detecting the water level at the open water level to open, an electrode rod 162d for detecting the water level at the closed water level for closing the city water inflow valve 163, and an electrode rod 162e for detecting the full water level. It has become. Note that the electrode type level switch 162 is not limited to having five electrode rods 162a to 162e, but may have three, four, or six or more electrode rods. Even in that case, it is preferable to detect the dry water level with an electrode rod that can detect the lowest water level, and to detect the full water level with an electrode rod that can detect the highest water level. Further, the water level for opening the city water inflow valve 163 is preferably lower than the water level for closing the city water inflow valve 163.

Here, in the electrode type level switch 162, by detecting a change in resistance value between each electrode rod 162b to 162e and the longest common electrode rod 162a, the water level in the water tank is adjusted to that of each electrode rod 162b to 162e. It is designed to detect that it is located higher than the bottom edge. That is, when the water level in the water tank 160 becomes higher than the lower end of each of the electrode rods 162b to 162e and conduction is established between the electrode rods 162b to 162e and the common electrode rod 162a by water, a detection signal for each water level is output. .

The water tank 160 may be provided with a float switch that is a water level gauge that detects the water level in the water tank 160 instead of or in addition to the electrode level switch 162. A detection signal from the float switch is input to the control unit 65 of the water supply device 10. Note that a plurality of float switches may be provided in order to detect the water level of drought, the open and closed water levels of the city water inflow valve 163, or the water level of full water. In this embodiment, which water level is detected by which electrode of the electrode level switch 162, whether the water stop inflow valve 163 is provided, etc. can be changed by the control parameters of the water supply device 10.

FIG. 3 is a diagram showing an example in which the water supply system of the water supply device 10 is a direct water supply system. In the example shown in FIG. 3, the water supply device 10 is used in a direct water supply type that uses the main pressure of the water main 173 and increases the pressure with a pump to supply water to the water tap 172 that is the target of water supply. There is. A pressure sensor 175 is provided in an inflow pipe 174 that communicates with the water main 173 . The pressure sensor 175 is a pressure measuring device for measuring the pressure of the water main 173, which is the inflow pressure of the pump. Hereinafter, "inflow pressure" shall indicate the pressure value detected by the pressure sensor 175. A detection signal from the pressure sensor 175 is input to the control unit 65 (I/O unit 70) of the water supply device. In this embodiment, the inflow pressure (the pressure of the water main 173) becomes below a certain level (for example, a value of 7 mAq is set in the setting code A10 as the detection value of the inflow pressure drop in the control parameters) and a predetermined time elapses (for example, When a value of 10 seconds is set in the setting code A11 as the detection time for a decrease in inflow pressure in the control parameters, the system enters the "inflow pressure decrease state." After that, when the inflow pressure exceeds a certain level (for example, the control parameter sets the value 10 to the setting code A12 as the detection value of the inflow pressure drop recovery).
mAq or more) and after a predetermined period of time has elapsed (for example, a value of 15 seconds is set in the setting code A13 as the detection time for recovery from inflow pressure drop in the control parameters), the inflow pressure drop state is resolved. The threshold value for detecting and recovering from the abnormality of the inflow pressure drop can be changed by a control parameter.

The water supply system 10 uses an elevated water tank method in which water that is pressurized by a pump is temporarily stored in a tank (elevated water tank) on the roof of the building 170, and water is supplied by natural flow. Good too. In the elevated water tank method, as explained in the water receiving tank method, an electrode rod is installed as a water level gauge to detect the water level in the elevated water tank and detects the water level of "full water" and "drought". It is preferable to detect whether the water tank is "full of water" or "drought."

[Configuration of water supply device]
Next, a specific configuration of the water supply device 10 of this embodiment will be explained. FIG. 4 is a plan view schematically showing an example of a water supply device and an external display according to this embodiment. As shown in the figure, in the water supply device 10, two pumps 30A, 30B and a pressure tank 50 placed between these pumps 30A, 30B are placed on a base 20. Further, the water supply device 10 includes a discharge pipe 40 connected to the discharge side of the pumps 30A and 30B, and a control panel 60 installed above the pressure tank 50. Each component will be explained below.

The base 20 is a stand on which each device such as the pumps 30A, 30B is mounted and fixed to the foundation, and has a substantially rectangular flat plate shape, and both sides in the longitudinal direction are bent downward and then removed. By being bent in the direction, L-shaped fixed sides 23, 23 are formed.

The water supply device 10 includes motors 33A and 33B that drive pumps 30A and 30B. The pumps 30A, 30B are provided with suction ports 35A, 35B, and discharge ports are provided on the upper surfaces of the pumps 30A, 30B. Note that the suction ports 35A and 35B correspond to the suction port 10A of the water supply device 10, and in the case of a direct water supply system, the suction ports 35A and 35B are connected to the inflow pipe 174 via a backflow prevention device (not shown). Further, the pumps 30A, 30B are attached with temperature sensors 36A, 36B which are temperature detectors for detecting pump overheating.

The discharge pipe 40 is a discharge confluence pipe of the pumps 30A and 30B, and is connected to both the pumps via flow switches 49A and 49B, which are a type of flow rate detector that detects the amount of water, and check valves (check valves) 47A and 47B. It is connected to discharge ports 37A and 37B of pumps 30A and 30B. Pumps 30A and 30B operate in parallel. Furthermore, the check valves 47A, 47B prevent water in the discharge pipe 40 from flowing back toward the pumps 30A, 30B when the pumps 30A, 30B are stopped. Further, the discharge pipe 40 is connected to a pressure tank 50, and a pressure sensor 48 is attached to the discharge pipe 40 to detect the pressure inside the pipe. Due to the effects of the pressure tank 50 and the check valves 47A and 47B, the pressure within the discharge pipe 40 after the pumps 30A and 30B are stopped is maintained at a constant pressure as long as water is not used. Hereinafter, "discharge pressure" shall indicate the pressure value detected by the pressure sensor 48.

In this embodiment, the configuration includes the pumps 30A and 30B and two pumps, but the number of pumps may be one or a plurality of three or more pumps.

The control panel 60 includes a case 61, which houses a power terminal (not shown), an earth leakage breaker for each pump, a noise filter, an induced lightning surge absorption element, a reactor, etc. It is configured to house a control section 65 consisting of various electric circuits for controlling operation.

[Block configuration of control unit]
FIG. 5A is a block configuration diagram for explaining an example of the configuration of this embodiment. In FIG. 5A, the control unit 65 of the water supply device 10, the monitoring device 210, the management device 310, and the external displays 80 and 280 are shown as functional blocks. The control unit 65 of the water supply device 10 includes a control memory (storage unit) 66, a calculation unit 69, an I/O unit (input unit and output unit) 70, an operation panel 79, and a communication unit 73. ing. The operation panel 79 includes a setting section 71 and a display section 72, and functions as a user interface. Note that the control unit 65 may be configured as a microcomputer that includes a CPU, memory, etc. and implements predetermined functions using software, or may be configured as a hardware circuit that performs dedicated arithmetic processing. Further, the control section 65 is not limited to being configured with one board, and for example, the communication section 73 and the operation panel 79 may be formed on separate boards. In that case, the control section 65, communication section 73, and operation panel 79 are connected by serial communication, wired communication such as a signal line, or wireless communication.

The setting unit 71 is used to set various parameters (setting information) by external operation (setting input). Specifically, the setting section 71 includes operation buttons, a touch panel, etc. (not shown), and various parameters set in the setting section 71 are stored in the control memory 66. As an example, a user or a worker inputs, as setting information (setting input), the stopping pressure, starting pressure, the content of the signal output from the external output, and other information necessary for control via the setting unit 71, Changes can be made at the installation site.

The display unit 72 displays various data such as control parameters stored in the control memory 66, the current operating status (operating information) of the pumps 30A and 30B, for example, the operation or stop of each of the pumps 30A and 30B, and the operating frequency. , current, inflow pressure, discharge pressure, trip of the inverter that drives the motor sections 33A and 33B, suction pressure drop alarm, water tank alarm, etc. are displayed.

In this embodiment, as the display section 72, a simple display such as a 7-segment LED and an indicator light can be used. However, the display section 72 is not limited to this example, and may be a dot matrix liquid crystal display or the like. Further, as the external display device 80, a high-performance display device using a liquid crystal screen using a touch input method or a push button method can be employed. In this case, simple information can be displayed on the display section 72, and a large amount of information can be displayed on the external display 80. With this configuration, the external display 80 displays information regarding the operating status of the pumps 30A, 30B by the control unit 65 (for example, target pressure SV, current pressure PV, operation/stop of the pumps 30A, 30B, 30B rotation speed, etc.) on the same screen, even users who are unfamiliar with water supply devices can recognize the status of the water supply device 10 and change settings without misunderstanding. Moreover, the water supply device 10 may be installed in an environment with a lot of electrical noise, such as a machine room or a pump room. In preparation for such a case, the display unit 72 may include a 7-segment LED, an indicator light, a mechanical push button, or the like, which is more resistant to electrical noise than a liquid crystal display or a touch panel. As a result, even if an abnormality occurs in the liquid crystal display or touch panel operation of the external display 80 due to electrical noise generated from the external environment, the display unit 72 can display and operate the minimum necessary for the operation of the water supply device 10. It can be performed. Therefore, the water supply device 10 can be installed even in an environment with a lot of electrical noise.

Note that the control section 65 may be provided with only the external display 80 without the operation panel 79 or the display section 72. In this case, all the functions of the operation panel 79 described above can be performed on the external display 80. Since there is no need to provide the water supply device 10 with the display itself, it is possible to further reduce the cost of the entire water supply device 10.

The control memory 66 stores a control program for controlling the water supply device 10, device information of the water supply device 10, failure history, operation history, control parameters input through the setting unit 71, external display 80, etc. Stored. When a failure occurs, information such as the failure history and the operation history of the water supply device 10 are periodically stored in the control memory 66. The control memory 66 also includes a first storage area 66a (first storage means) in which current control parameters and/or user information based on the parameters are stored. Furthermore, the control memory 66 has a second storage area 66b (second storage means) that stores control parameters and/or user information that are changed by the change request when a predetermined change request is made. Equipped with Here, "control parameters that are changed by a change request" means the object for which a control parameter change request is made (e.g., control code) and the changed value of the object (e.g., reassigned value) due to the change request. . The control parameters to be changed by the change request indicate information that is at least partially different from the current control parameters until the change by the change request is finalized.

As the control memory 66, nonvolatile memories such as ROM, HDD, EEPROM, FeRAM, and flash memory, and volatile memories such as RAM are used. The control memory 66 stores various data, such as calculation result data (operating time, integrated value, etc.) in the calculation unit 69, pressure values (inflow pressure, discharge pressure), setting value information input through the setting unit 71, And data input through the I/O unit 70 or output through the I/O unit 70 are stored.

The communication unit 73 is configured to be able to communicate with the external display 80 by wired or wireless communication. As the wireless communication, for example, near field communication (NFC) technology can be used. Further, any type of wireless communication such as Bluetooth (registered trademark) and Wi-Fi can be used. However, NFC is advantageous in that communication can be completed simply by bringing the control unit 65 and external display 80 close together. In addition, as wired communication, for example, the control unit 65 may be provided with an external connection terminal such as a USB (Universal Serial Bus), and the external display 80 may be connected to the communication terminal, or RS422, Serial communication such as RS232C or RS485 may also be used.

As the I/O section (input/output section) 70, a port or the like is used. The I/O section 70 receives signals from the pressure sensor 48, signals from the flow switches 49A, 49B, etc., and sends the input signals to the calculation section 69. As the calculation unit 69, a CPU is used. The calculation unit 69 sets various data for operating the pumps 30A and 30B based on the program and various data stored in the control memory 66 and signals input from the I/O unit 70, and Calculations and the like are performed, and a control command is output from the I/O section 70.

Further, as described above, the I/O unit 70 receives the signal from the electrode level switch 162 when the water supply device 10 is used in the water tank type, and when the water supply device 10 is used in the direct water supply type. A signal from pressure sensor 175 is input. The I/O section 70 has an input terminal 70b including at least one terminal, and receives other signals, such as signals from the pressure sensor 48, flow switches 49A, 49B, and temperature sensors 36A, 36B.

The I/O section 70 and the inverters that drive the pumps 30A and 30B are connected to each other by communication means such as RS422, RS232C, and RS485. Control signals such as various setting values, frequency command values, start/stop signals (run/stop signals) are sent to the inverter from the I/O section 70, and actual frequency values are sent from the inverter to the I/O section 70. The operating status (operating information) such as current and electric current values are sent sequentially.

Note that analog signals and/or digital signals can be used as control signals transmitted and received between the I/O section 70 and the inverters that drive the pumps 30A and 30B.
For example, an analog signal can be used for the rotation frequency, etc., and a digital signal can be used for the operation stop command, etc. Further, if variable speed control of 30A and 30B is not performed, the inverter may not be provided.

Further, the I/O section 70 has an external output terminal 70a including at least one terminal, and the external output terminal 70a is, for example, a terminal block and is mounted on a board constituting the control section 65.

Ru. In other words, a signal indicating the content of the signal to be output in response to various states of the water supply device 10 is sent to the control parameters assigned to each of the plurality of terminals A1, A2, B1, B2, B3, C1, and C2.

Note that the external display 280 has the same or the same function as the external display 80 described later, and the same terminal may be used as the external display 280 and the external display 80.

For example, the monitoring device 210 can have a simple configuration that simply turns on/off a lamp based on a signal from the external output terminal 70a of the water supply device 10. In this case, the lamp corresponds to an example of the display section 213. Furthermore, the monitoring device 210 may be configured as a microcomputer that includes a CPU, memory, etc. and implements predetermined functions using software, or may be configured as a hardware circuit that performs dedicated arithmetic processing.

Further, the monitoring device 210 is not limited to being configured by a single device, but may be configured by, for example, a plurality of devices provided apart from each other.

The external display 80 (external terminal) has an operation display section 80A, and is configured to communicate with the communication section 73 of the water supply device 10 to display and change various data regarding the water supply device 10. Specifically, the external display 80 receives various data stored in the control memory 66 from the communication section 73 of the water supply device 10 and displays it on the operation display section 80A. Further, the external display device 80 transmits a request to change various data inputted by the user by operating the operation display section 80A to the communication section 73 of the water supply device 10.

In this case, the display unit 72 of the water supply device 10 may display simple information, and the external display 80 may display a large amount of information. With this configuration, the external display device 80 can display a plurality of pieces of information among the various data stored in the control memory 66 on the same screen of the operation display section 80A. Therefore, even a user who is unfamiliar with the water supply device 10 can recognize the state of the water supply device 10 and input settings without misunderstanding, rather than displaying the operation only on the operation display section 80A.

Note that all the functions of the operation panel 79 described above may be implemented on the external display 80. In this way, even if the water supply device 10 is installed in a place where it is difficult to operate (for example, the operation panel 79 is near the operator's feet), operations such as checking the status of the water supply device 10 and changing setting value information become easy. . Further, all the functions of the external display device 80 described above may be implemented on the operation panel 79.

The initial mode for displaying and/or changing the status and control parameters of the water supply device 10 is the first mode, in which predetermined personal identification methods such as password input by the operator and fingerprint authentication are used. The mode changes from the first mode to the second mode by a predetermined restriction release operation, and returns from the second mode to the first mode by a lapse of time due to no operation by the operator or by a predetermined initialization operation. Restriction release operation methods such as passwords and password entry procedures are disclosed only to specific operators, the first mode can be used even by users who have not been disclosed the restriction release operation method, and the second mode is for restriction release operation.

In this embodiment, the control parameter setting value information includes a signal type (input/output signal type) indicating the content of the signal of each terminal. For the input/output signal type, a setting code is assigned to each terminal in the I/O section 70, and the user can input/output a signal indicating which content from which terminal by changing the "value" of the setting code. You can set Furthermore, as shown in FIG. 7B, data table B may store terminal names, terminal types, AR markers, and the like as control parameters whose settings can be changed.

Data table C shown in FIG. 7C is a control parameter indicating the relationship between the "value" in FIG. 7B and the signal type (input/output signal type) indicating the content of the signal. Specifically, in FIG. 7B, the value 1 is set in the setting code P11. In FIG. 7C, the value 1 means that the signal type 1 is "all-operation", and therefore the all-operation signal is output from the terminal A1. Furthermore, the data table C may store a plurality of signal types as changeable control parameters, as shown in FIG. 7C.

Here, an example of the content of the signal to be output corresponding to the value set for signal type 1 will be explained. Note that the following example also includes signal types not shown in FIG. 7C.

The contents of the signals corresponding to "full water" and "drought" of the elevated water tank are as follows: When the water supply method is the elevated water tank method, the ON signal is activated when the elevated water tank (not shown) is in the full water state and in the dry state, respectively. This is a signal that is output as an OFF signal when the elevated water tank is not in a full water state or in a dry state.
Further, an example of the contents of the input signal (signal type 3=input) corresponding to the value set for signal type 1 is shown below.

[Water supply control by water supply device 10]
An example of water supply control of the water supply device 10 by the control unit 65 will be described. When the discharge pressure decreases to a predetermined starting pressure while the pumps 30A and 30B are stopped, the control unit 65 starts at least one of the pumps 30A and 30B. Specifically, the control unit 65 issues a command to the motor units 33A, 33B (or the inverter if an inverter is provided) to start driving the pumps 30A, 30B. While the pumps 30A and 30B are in operation, control such as estimated terminal pressure constant control or target pressure constant control is performed based on the set pressure (set pressure). Specifically, in the case of estimated terminal pressure constant control, the target pressure (SV
), and in the case of constant target pressure control, the set pressure is set as the target pressure (SV). Further, the discharge pressure is defined as the current pressure (PV). Then, a PI calculation or a PID calculation is performed based on the deviation between SV and PV, and the command rotation speed of the pumps 30A and 30B is set. In addition, when performing estimated terminal pressure constant control with direct water supply, the target pressure control curve may be corrected based on the inflow pressure. Specifically, the target pressure (SV) is calculated by adding the inflow pressure to the target pressure control curve. Further, when there are a plurality of pumps as in this embodiment, the control unit 65 also controls the number of pumps according to the water amount by determining the number of pumps that can be started at the same time (the number of pumps operating in parallel). In the water supply device 10 of this embodiment, the settings of control parameters related to pump control, such as the set pressure, the number of pumps, and whether to perform constant estimated terminal pressure control or constant pressure control, can also be changed.

When the water usage in the building decreases while the pumps 30A, 30B are in operation, the flow switches 49A, 49B detect the insufficient amount of water and send the detection signal to the control unit 65. When the control unit 65 receives this detection signal, it issues a command to the pumps 30A, 30B to operate the pumps 30A, 30B at a predetermined rotation speed. When the control unit 65 determines that pressure has accumulated in the pressure tank 50 when the discharge pressure reaches a predetermined operation stop pressure, the control unit 65 stops the pumps 30A and 30B (stops the small amount of water). When water is used again in the building after the pumps 30A and 30B stop producing a small amount of water, the discharge pressure decreases to below the starting pressure and the pumps 30A and 30B start. In addition, when there are multiple pumps as in this embodiment, it is preferable to rotate the pumps 30A, 30B to be started to prevent water from accumulating in the pumps 30A, 30B. Moreover, as a method of detecting the small amount of water, other means such as a low load based on the current value of the motor sections 33A and 33B or a shutoff pressure may be used instead of using the flow switches 49A and 49B.

Further, in this embodiment, the control unit 65 determines the water supply method etc. by referring to the control parameters stored in the control memory 66, for example, various information shown in FIGS. 7A to 7D. Particularly in the case of the water tank system, water tank control is executed by determining information such as the number of water tanks and the number of electrodes of the electrode level switch 162 from the control parameters. Specifically, if the control unit 65 determines from the control parameters that the water tank is a single tank type and the number of electrode rods is five, when the electrode rod connected to the input terminal E14 is exposed from the water surface, the water tank is closed. It is determined that the water level at 160 has become lower than the drought water level, and the water level state is set as a drought state. In the drought state, the control unit 65 forcibly stops the pumps 30A and 30B and issues a drought alarm, and thereafter, when a part of the electrode rod connected to the input terminal E13 is submerged in water, it determines that the water level is above the drought recovery level, Both the forced stop of the pumps 30A and 30B and the drought alarm are canceled. Further, when a part of the electrode rod connected to the input terminal E11 is submerged in water, the control unit 65 determines that the water level in the water tank 160 has become higher than the full water level, sets the water level state to the full water state, and issues a full water alarm. emits. Further, when the electrode rod connected to the input terminal E12 is exposed from the water surface, the control unit 65 determines that the water level in the water tank 160 has become lower than the water reduction level, sets the water level state to the water reduction state, and issues a water reduction alarm. After that, when a part of the electrode rod connected to the input terminal E1 is submerged in water, it is determined that the water level is higher than the low water recovery level, and the low water state and low water level alarm are canceled. The control unit 65 sets the water level state to a normal state when none of a full water state, a low water state, and a drought state occur.

[Control parameter settings]
Next, setting of control parameters in the system 1000 will be explained. By displaying user information based on the control parameters when changing the settings of the control parameters stored in the water supply device 10, the user can confirm what will be affected by the settings change. Furthermore, in this embodiment, the change in the setting of the control parameters is finalized after a predetermined operation is performed by the user with reference to the user information. In a pump device such as the water supply device 10, if the setting code and the value of the control parameter are disclosed to the user so that the user can easily change the value of the control parameter, it is possible for a user unfamiliar with the pump device to change the value to an incorrect value. Settings may be changed, and in the worst case, water may be cut off. Therefore, it is preferable to ensure security to prevent incorrect settings. Therefore, in this embodiment, different disclosure contents are displayed for the first operator and the second operator. Settings can be changed without the user having to know the setting code or specific value of the control parameter. That is, the user information is disclosed to the first operator in place of or in addition to the setting code and specific value of the control parameter, and the setting code and specific value of the control parameter is disclosed to the second operator. Therefore, security can be ensured to prevent incorrect settings. Furthermore, when control parameters are changed, if the change information is not shared with workers who perform maintenance work, inquiries from users and work by workers may become complicated. In this embodiment, since the management device 310 stores the change history of the control parameters, a worker can check the change information during maintenance, inspection, emergency response in case of an abnormality, etc.

In this embodiment, when resetting the input/output signal type when an abnormality occurs in some of the external output terminals 70a and/or input terminals 70b (hereinafter also simply referred to as "terminals") of the input/output section, We will explain the method. In the water supply device 10, some terminals may become abnormal due to deterioration of the device over time or a lightning strike. In the system 1000 of this embodiment, when such an abnormality occurs, the user refers to the user information displayed on the external display 80 and performs a predetermined operation, thereby generating input/output signals of the terminals stored in the water supply device 10. The configuration is such that control parameters for each type can be reset.

There is a possibility that an abnormality may occur in the water supply device 10, such as a terminal for inputting or outputting a signal not being able to input/output a correct signal due to deterioration of the device over time or a lightning strike. If the abnormality occurs in only some of the terminals, a control parameter that allows you to change the input/output signal type of the terminal where the abnormality has occurred without replacing the input/output section or the entire control section 65 having the input/output section. It may be possible to use the device by reconfiguring the settings. However, if the control parameters of the pump device can be easily changed, there is a risk that the settings may be changed erroneously by someone unfamiliar with the pump device, which may affect the water supply, such as causing the pumps 30A and B to not operate correctly. Therefore, in this embodiment, instead of the user checking the corresponding setting code and changing the control parameters related to external input/output, connection information related to external input/output is created as user information, and the user information is transferred to the external display 80. to be displayed. Then, the user who has confirmed the user information is allowed to select whether or not to change the information, and when the user selects the change, the control unit 65 changes the corresponding control parameter through communication. By doing so, the user can change the input/output signal type to a desired configuration without being aware of the control parameters. Here, the connection information related to external input/output displayed as user information is information related to a water level signal input from the water tank 160, which is an external device, to the control unit 65, and/or information from the control unit 65 to the external device. This is information related to the output signal output to the monitoring device 210.

Furthermore, if the control section 65 loses the setting information of the input/output signal type in the device due to lightning or the like, it is replaced with a new one. At the time of this replacement, in the conventional device, it is required to reset the input/output signal type for each of the plurality of terminals one by one, which makes the setting work complicated. Therefore, in response to a predetermined change request, the management device 310 creates connection information regarding external input/output as user information based on the stored change history of control parameters, and transmits it to the control unit 65. The control unit 65 displays the user information on the external display 80. Then, the user or worker who has confirmed the user information is allowed to select whether or not to change the information, and when the user or worker selects the change, the control unit 65 changes the setting of the corresponding control parameter through communication. By doing so, the user or worker can change the input/output signal type to the desired configuration without being aware of the control parameters, and recovery can be achieved faster than changing the settings of the control parameters from the operation panel 79 or the like. Can be done.

The operation when resetting the input/output signal type of the I/O unit 70 in the system 1000 will be explained using FIG. 8A and FIG. 8B.
FIG. 8A is a functional block diagram showing the main functions when resetting the input/output signal type of the I/O unit 70 in the system 1000. FIG. 8B shows the I/O unit 7 in the system 1000.
FIG. 7 is a diagram illustrating an example of an operation when resetting an input/output signal type of 0; FIG. 8B is executed by the system 1000, for example, when a failure occurs in some of the terminals or in response to a request from the user to display the terminal status.

In this embodiment, as shown in FIG. 8A, the control unit 65 includes a pump control means 530 that performs control based on control parameters (for example, discharge pressure control, water tank control, external output, etc.). The management device 310 includes a control parameter management unit 511 that manages control parameters for each of the plurality of water supply devices 10 to be managed, and a change history creation unit 512 that creates a change history of the control parameters. The external display 80 displays a change confirmation input means 521 for the user to confirm a change in the control parameters of the water supply device 10, an abnormal terminal identification means 522 for the user to input a faulty terminal, and predetermined user information. and user information display means 523. Furthermore, the management device 310 includes a control parameter reassignment creating means 501 and a user information creating means 502.

The external display device 80 acquires the current value of the control parameter from the management device 310 at a predetermined timing such as a request from the user to display user information regarding the external output terminal (step SB02). Then, an abnormality information input screen whose details are shown in FIG. 9B is displayed on the operation display section 80A (step SB04), and an input of abnormality information from the user is waited for (step SB10: No). In step SB10, when at least one of the selection sections 807a1 to 807c2 and the abnormality input button 809, which will be described later with reference to FIG. 9B, are selected (step SB10: Yes), the external display 80 displays abnormality information of the selected terminal. is transmitted to the management device 310 (step SB12). As mentioned above, if an abnormality occurs in only some terminals, it is possible to change the type of signal input or output from multiple terminals without replacing the input/output section or the entire control section that has the input/output section. It is possible that the device can be used by resetting certain input/output signal types. Therefore, the abnormal input to the terminal in step SB10 functions as a control parameter change request.

When the management device 310 receives the terminal abnormality information transmitted in step SB12 from the external display device 80, it creates control parameter reassignment based on the received abnormality information. Specifically, the reassignment creating means 501 of the management device 310 creates a reassignment of the input/output signal types of the plurality of terminals of the I/O unit 70 (step SC20). The reassignment creation means 501 creates control parameters to be changed in response to a user's change request. Specifically, the reassignment creating means 501, which has received the terminal abnormality input as a change request, excludes the terminal in which the abnormality has occurred based on the abnormality information from the external display 80, and adjusts the input/output of a plurality of terminals. It is a good idea to create a signal type reassignment. For example, assume that the user inputs to the external display 80 an input indicating that an abnormality has occurred in the external display terminal B1. In this case, upon receiving the information from the external display device 80, the reassignment creating means 501 removes the assignment of the signal type to be output from the external display terminal B1, and assigns the removed signal type to another external display terminal. Good too.

In this embodiment, as an example of reassignment of control parameters by the reassignment creating means 501, the signal type ("full water ” shall be assigned. Specifically, in this embodiment, the storage unit 366 of the management device 310 has the same data as data tables A to D stored in the control memory 66 of the water supply device 10. When the management device 310 receives information indicating that an abnormality has occurred in the external display terminal B1 from the external display device 80, the reassignment creation means 501 refers to the data table B stored in the storage unit 366, and Confirm that "3" indicating full water is currently assigned to the value of external display terminal B1 (value of setting code P13). Subsequently, the management device 310 determines that the value of the external display terminal B1 becomes "0" and that the value of the external display terminals A1 to C2 is set to "0" (no assignment) (as an example, The reallocation information is created so that the value of the terminal C1) (as an example, the value of the setting code P16) becomes "3". Note that the management device 310 may change the value of the external display terminal B1 to the value "999" indicating an abnormality instead of the value "0" corresponding to no assignment. Due to the reassignment of control parameters by the reassignment creation means 501, the input/output signal types for terminals other than the terminal where the abnormality has occurred do not change, so the water supply device 10 changes the input/output signal types of the I/O section 70. When resetting, wiring changes between the I/O unit 70 and the monitoring device 210 can be minimized.

Subsequently, the management device 310 creates user information based on the created control parameter reassignment (step SC22), and transmits the created user information to the external display device 80 (step SC24). In this manner, in the present embodiment, the management device 310 does not transmit the reassigned control parameters to the external display device 80 before the user confirms the change of the control parameters, and the management device 310 transmits the reassigned control parameters to the external display 80. Send information to external display 80. The external display device 80 then stores the user information received from the management device 310 in the second storage means (step SB28).

The external display 80 displays the user information stored in the second storage means on the operation display section 80A (step SB30). The display of the user information in step SB30 corresponds to an example of the display in the "first display step." In step SB30, the user information is set with access rights that restrict both downloading and printing. That is, when displaying user information on the operation display unit 80A before changing the settings of control parameters in the water supply device 10, both downloading and printing of the user information are restricted.

In the present embodiment, the operation display unit 80A also includes a confirmation input means (change confirmation button in FIG. 830). When a change confirmation input is input by the user using the change confirmation input means (step SB34), information indicating the change confirmation input is transmitted from the external display 80 to the management device 310 (step SB36: Yes). Since the external display device 80 has the final input means for accepting the final input from the user, unintended changes in the control parameters can be suppressed. Further, a company that provides a remote monitoring service for the management device 310 can use the timing of this change confirmation input to indicate to the user the charges that will be incurred, the terms of use, and the like. This makes it possible to prevent trouble between the vendor and the user when changing control parameters remotely from the management device 310.

When information indicating a change confirmation input is transmitted from the external display device 80 to the management device 310 (step SB36), the management device 310 stores in the storage unit 366 that the change confirmation input has been received, and sets the reallocation control parameters. is converted into transmission data (step SC40). Then, the management device 310 transmits the control parameters for reallocation to the external display device 80 (step SC42). Here, the management device 310 may transmit only the control parameters to be changed by reassignment, or may transmit a series of control parameters including the control parameters to be changed. As described above, in this embodiment, the management device 310 transmits the reassigned control parameters to the external display device 80 after the user confirms the change of the control parameters. That is, the management device 310 first transmits user information based on the control parameters for reassignment to the external display 80 (step SC22), and after the user confirms the change in the control parameters (step SB34: Yes), the management device 310 The control parameters are transmitted to the external display device 80 (step SC42). Upon receiving the reallocation control parameters from the management device 310, the external display device 80 transmits the received reallocation control parameters to the water supply device 10 without displaying them (SB50). In addition, the management device 310 and the water supply device 1
0 can communicate directly with the water supply device 10 via a network or the like, the management device 310 may directly transmit the control parameters to be changed to the water supply device 10 without going through the external display device 80.

Next, the water supply device 10 changes the setting parameters stored in the control memory 66 according to the received reallocation control parameters (step SA60), and sends a change completion signal indicating completion of the change to the external display. 80 (step SA62).

Upon receiving the change completion signal, external display 80 transmits the received change completion signal to management device 310 (step SB70). Upon receiving the change completion signal, the management device 310 determines the control parameters for reallocation (step SC72) and creates a change history (step SC74). Note that if the management device 310 and the water supply device 10 can communicate directly via a network or the like, the water supply device 10 may directly transmit the change completion signal to the management device 310 without going through the external display 80. .

Furthermore, upon receiving the change completion signal in step S62A, external display 80 displays user information based on the changed control parameters on operation display unit 80A (step SB80). The display of the user information in step SB80 corresponds to an example of the display in the "second display step." At step SB80, the user information is displayed with access rights set for the user to allow downloading and/or printing. That is, when the user information is displayed on the operation display unit 80A after changing the settings of the control parameters in the water supply device 10, downloading and/or printing of the user information is permitted. This allows users to manage user information on their own computers (storage devices) or paper media.

At step SB30, where the change of the control parameters is not completed, both downloading and printing of user information is disabled, and at step SB80, when the change of the control parameters is complete, downloading and/or printing of the user information is permitted. The water supply device 10 may be installed in a poor communication environment, such as being subject to electrical noise from a pump room or the like, having difficulty in receiving radio waves, or being affected by vibrations of the pumps 30A and 30B. Therefore, after the user confirms the change, there is a concern that the change of the control parameter to the control unit 65 may fail in any one of steps SB36 to SB62. However, in the present embodiment, downloading and/or printing is permitted in step SB80 after receiving the completion of change in step SB62, so the user can receive user information based on the control parameters executed in the control unit 65. can be managed on a separate storage device or paper medium.

Further, in this embodiment, the operation display section 80A includes a history display requesting means that allows the user to request whether or not to display the history on the operation display section 80A. When a history display request is made by the user using the history display request means (step SB90: Yes), a change history transmission request signal for requesting transmission of the change history is transmitted to the management device 310 (step SB92). Then, the management device 310 that has received the change history request signal transmits the change history created in step SC74 to the external display device 80 (step SC100), and the external display device 80 that has received the change history Based on this, the operation display unit 80A displays the information (step SB110).

In this way, the present embodiment includes a water supply device 10 that includes the pumps 30A and 30B, a control section 65 that performs pump control based on control parameters that can be set, and an external display of the water supply device 10 that is a display section. A system 1000 including a display unit 80 and a management device 310 provides a management method for managing control parameters of the water supply device 10. In this management method, when a predetermined change request (for example, input of abnormality information of an input/output terminal in step SB10) is made, a control parameter changed by the change request and user information based on the changed control parameter are made. and a first display step (step SB30) of displaying user information based on the control parameters to be changed on the external display 80. The process further includes a changing step (step SA60) of changing the control parameters of the control unit 65 after displaying the user information in the first display step. The system 1000 includes a confirmation input means (change confirmation button 830) for determining whether or not the user changes the control parameters based on the user information shown in the first display step. When the change of the control parameters is confirmed in the confirmed input receiving step (step SB34) of accepting input, the control section 65 executes the changing step (step SA60).

Next, control parameters and user information based on the control parameters will be explained.
The user information is used on the external display 80 to display to the user information that may affect the user in relation to the control parameters. Therefore, in the following, the display on the external display 80 will be explained, as well as the control parameters and user information.

The external display 80 displays, as display information, a graphic indicating the arrangement of the terminals and the type of signal input/output by the terminal (input/output signal type). The external display 80 has user information display means 523. The user information display means 523 displays graphics based on the control parameters of the water supply device 10 on the operation display section 80A.

9A and 9B show examples of displays in the system 1000. FIG. 9A is a diagram showing an example of display of control parameters. FIG. 9B shows an example of a display of user information. Specifically, in FIG. 9A, control parameters and their values are displayed, and FIG. 9B is an example of display of user information when setting codes P11 to P17, which are control parameters, have the values shown in FIG. 9A. In the first mode, FIG. 9B is displayed, and in the second mode, FIG. 9A is displayed in addition to or instead of FIG. 9B.

FIG. 9B shows an example of the display of user information on the external display 80 in step SB10 of FIG. 8B.
FIG. 9B shows a graphic display of the arrangement of the external output terminals 70a and the signal types (input/output signal types) output from the external output terminals 70a. The arrangement of these external output terminals 70a and the input/output signal types are an example of user information related to the output signal output from the control unit 65 to the monitoring device 210, which is an external device. As described above, this user information is created by the user information creation means 502. The user information creation means 502 has a plurality of user information associated with each setting code and setting value as a user information group, and selects user information to be displayed from the user information group at a predetermined timing. When a signal type is included in the control parameters changed by a change request, the user information created by the user information creation unit 502 includes the arrangement order of the plurality of terminals of the external output terminal 70a and the respective signal types in the arrangement order. It is preferable that the wiring diagram shows the following. Specifically, the user information creation means 502 first draws the arrangement order of each terminal of the external output terminal 70a based on the information in the data table D of the control memory 66, and then draws it in the same order as the arrangement order. The arranged input/output signal types are plotted based on the information in data table B. In this way, the user information creation means 502 creates the graphic shown in FIG. 9 as user information. The user information creation means 502 stores the created user information as a user information group in association with the control parameter setting code and its value. Alternatively, the external display device 80 may have in advance a plurality of graphics corresponding to the arrangement order of all the external output terminals 70a and input/output signal types created by the user information creation means 502 as a user information group.

Here, the graphical display of the terminal may include graphically displaying identification information for identifying the terminal. By displaying such user information, the user may:
The wiring between the control section 65 and the monitoring device 210 can be easily recognized compared to checking the operation display section 80A in which only the control parameter setting code and its value are displayed as shown in FIG. 9A. Note that in the example shown in FIG. 9B and the display described later, the arrangement of signals and input/output signal types of the external output terminal 70a are shown, but instead of or in addition to this, the arrangement of signals and the input/output signal of the input terminal 70b are shown. The signal type may also be displayed in the same way.

The display on the operation display section 80A will be described in detail. In the example shown in FIG. 9B, a terminal graphic section 802 that graphically displays the arrangement order of each terminal of the external output terminal 70a, a connection diagram graphic section 806 that indicates the conduction inside the water supply device 10 at the external output terminal 70a with a connection, and an external output A signal type text information section 808 that indicates the signal type indicating the content of the signal output from each of the terminals 70a using text information is displayed on the operation display section 80A of the external display 80. Note that the signal type character information section 808 may be displayed based on the information of the data table B acquired from the water supply device 10 and also based on each value of the data table C, for example.

The arrangement order of each terminal of the external output terminal 70a shown in the terminal graphic section 802 is shown in the same order as the arrangement of the terminals on the actual board shown in FIG. This makes it easy to perform correct wiring by referring to the user information. Specifically, the terminal graphic unit 802 graphically displays the arrangement of the external output terminals 70a in the same order as in the data table D of FIG. 7D, that is, external display terminals A1, A2, external display terminal A1. , A2 common terminal ACM, external display terminals B1, B2, B3, external display terminals B1, B2, B3 common terminal BCM, external display terminals C1, C2, and external display terminals C1, C2 common terminal They are displayed in order of CCM. In addition, the terminal graphic part 802 is a graphic in an arrangement that matches or corresponds to the arrangement order of the external display terminals A1, A2, B1, B2, B3, C1, C2, ACM, BCM, and CCM in the actual water supply device 10. It would be nice if it were displayed. Further, the arrangement order of the terminals may be a fixed value stored in the external display 80 and/or the control unit 65 as device information instead of setting information. Further, in the example shown in FIG. 9B, a terminal type text information section 804 is displayed next to the terminal graphic section 802, which indicates "external display terminal" as text information. The terminal type character information section 804 may be displayed based on, for example, each value of the terminal type in the data table B acquired in step SB02. This makes it easier for the user to understand that the display in the terminal graphic section 802 indicates an external display terminal.

In the example shown in FIG. 9B, the terminal graphic unit 802 graphically displays the external output terminal 70a using figures and characters; however, the present invention is not limited to this example, and for example, the external output terminal of the actual water supply device The external output terminal 70a may be graphically displayed using the image 70a. Further, the external display device 80 may graphically display the external output terminal 70a using augmented reality (AR). Specifically, in the control unit 65, identification marks M1 and M2 for identifying the external output terminal 70a are printed on a board on which the external output terminal 70a is mounted. By disposing the identification marks M1 and M2 on the side of the external output terminal 70a, the imaged external display 80 can identify the arrangement order, size, etc. of the external output terminal 70a. The external display device 80 further includes an imaging device that captures an image of the control unit 65 including the identification marks M1 and M2 and the external output terminal 70a, and displays the captured image of the external output terminal 70a and the image obtained from the identification marks M1 and M2. The information, a connection diagram graphic section 806 based on the information acquired from the water supply device 10, and a signal type character information section 808 are combined and displayed on the operation display section 80A. Furthermore, when the AR display button 810 provided on the operation display section 80A is pressed, the external display device 80 graphically displays the external output terminal 70a using augmented reality, and the AR release button provided on the operation display section 80A is pressed. When 812 is pressed, the augmented reality display may be canceled and the terminal graphic section 802 may be used to graphically display the external output terminal 70a. In addition, when graphically displaying the external output terminal 70a using augmented reality, external outputs such as "A1", "A2", "B1", "B2", "B3", "C1", and "C2" are displayed. At least one of the text information for identifying the terminal 70a, the wiring diagram graphic section 806, and the signal type text information section 808 may be shown together with the captured image of the external output terminal 70a.

As shown in FIG. 9C, the external display 80 has the following steps as a display method using augmented reality.
(Step 141)
an imaging step of imaging any terminal of the input/output unit 70; At this time, identification marks (AR markers) M1 and M2 corresponding to the input/output units to be imaged are also imaged.
(Step 142)
In the captured image of the terminal of the input/output unit 70, a graphic (terminal graphic unit 802) indicating the arrangement of signals in the input/output unit 70, a signal type (terminal type character information unit 804, a wiring diagram graphic unit 806, An image synthesis step of synthesizing the signal type character information section 808).
Specifically, the captured image of each terminal of the input/output section 70 and each terminal of the terminal graphic section 802 are synthesized so as to overlap, and next to the synthesized terminal graphic section 802 is a terminal type character information section. 804, the connection diagram graphic section 806, and the signal type character information section 808, at least one of them is synthesized so that they are displayed together. Further, in this step, it is preferable that a highlighted display section 849, which will be described later, is also synthesized.
(Step 143)
a display step of displaying the combined image of the input/output unit;

Since the control unit 65 has identification marks M1 and M2 corresponding to each input terminal of the input/output unit 70 on the same board as the input/output unit 70, in the above-mentioned imaging step, the terminal to be imaged and the identification marks corresponding to the terminal are identified. The identification marks M1 and M2 can be imaged simultaneously. Then, in a synthesis step, information based on the imaged identification marks M1 and M2 is synthesized with the image of the input/output unit 70. In addition, in this embodiment, the identification marks M1 and M2 are arranged on both sides of the corresponding terminals, as shown in FIG. This makes it easy to simultaneously image the terminal to be imaged and the identification marks M1 and M2 corresponding to the terminal. In one embodiment, the identification marks are not limited to being placed at both ends of the corresponding terminals, but may be placed near the corresponding terminals so that the same image can be captured in step 141.

The connection diagram graphic section 806 graphically displays a connection diagram showing a connection state due to conduction between the external output terminal 70a and the water supply device 10. Specifically, in the example shown in FIG. 9, the connection diagram graphic part 806 indicates that the external display terminals A1 and A2 indicate ON/OFF signals indicating whether or not they are electrically connected to the common terminal ACM, and the external display terminal B1 , B2, and B3 indicate ON/OFF signals indicating whether or not conduction is established with the common terminal BCM, and external display terminals C1 and C2 indicate ON/OFF signals indicating whether conduction is established with the common terminal CCM. The connection diagram graphic section 806 may be displayed based on, for example, each common value of the data table B acquired in step SB02.

The signal type character information section 808 is displayed adjacent to the terminal graphic section 802. Specifically, in the example shown in FIG. 9, a signal indicating "all operations" is output from the external display terminal A1 based on the values of P11 to P17 of the data table B acquired in step SB02, and the external A signal indicating "failure all at once" is output from the display terminal A2, a "full water" signal is output from the external display terminal B1, a signal indicating "low water" is output from the external display terminal B2, and the external display terminal B1 outputs a signal indicating "low water". A signal indicating "drought" is output from terminal B3, and it is shown that no output signal is assigned to external display terminals C1 and C2. In this way, the terminal graphic section 802 is arranged in an order that matches or corresponds to the arrangement order of the external display terminals A1, A2, ACM, B1, B2, B3, BCM, C1, C2, and CCM in the actual water supply device 10. In addition, the signal type indicating the content of the signal output from the external output terminal 70a is also displayed adjacent to the terminal graphic section 802, so that the user can easily understand the external output terminal of the water supply device 10. Wiring work between the 70a and the monitoring device 210 and confirmation of the wiring connections can be easily performed.

The external display 80 displays, in at least one of the terminal graphic section 802, the wiring diagram graphic section 806, and the signal type character information section 808, the signal type corresponding to the external output terminal 70a that is currently in the ON state in a highlighted display section 849. Highlight. The highlighted display section 849 indicating the ON signal in the conductive state may be displayed based on the value acquired in step SA0, for example. Specifically, here, in the control unit 65, since the terminal A1 is outputting an ON signal, the words "all operations" are highlighted with a thick frame line. Thereby, the user can easily understand by looking at the external display 80 that the external display terminal A1 is outputting an ON signal. Note that in the highlighted display, instead of or in addition to the thick frame in the highlighted display section 849, it is sufficient to distinguish the terminal from the OFF state by lighting, blinking, font, character size, display color, etc. The highlighting section 849 graphically displays the external output terminal 70a that is currently ON and the external output terminal 70a that is currently OFF, and graphically displays the state of the signal output from the external output terminal 70a. This is an example of "input/output information display".

Further, the operation display section 80A is provided with selection sections 807a1 to 807c2 corresponding to the external output terminals 70a and a terminal abnormality input button 809. 809 is selected, the external display 80 determines that abnormality information of the selected terminal has been input. Note that the abnormality input button 809 is not limited to one that is always provided on the operation display section 80A, but may be displayed on the operation display section 80A when the user performs a predetermined operation on the external display 80.

Note that the name used for the type of signal of the external output terminal 70a displayed on the external display 80 may be stored as setting value information in the management device 310, the control memory 66, and/or the external display 80. Alternatively, it may be stored as a fixed value as device information. However, if it is stored as setting value information, it becomes easy to change the display, etc. In this way, the user information creation means creates display information based on each value of the data tables A to D, which are control parameters.

10A and 10B show examples of displays in the system 1000.
FIG. 10A is a diagram illustrating an example of a display of the reassignment control parameters created by the reassignment creating means 501 of the management device 310. FIG. 10B shows an example of a display of user information. Specifically, in FIG. 10A, control parameters and their values are displayed, and FIG. 10B is an example of the display of user information when the setting codes P11 to P17, which are control parameters, have the values shown in FIG. 9A. In the first mode, FIG. 9B is displayed, and in the second mode, FIG. 9A is displayed in addition to or instead of FIG. 10B. FIG. 10B is a diagram showing an example of the display on the external display 80 in step SB30 of FIG. 8B.

FIG. 10A shows an example in which the control parameters stored in the second storage means at step SB30 in FIG. 8B are displayed on the external display 80 in the second mode. As shown in FIG. 10A, in the second mode, control parameter setting codes and their setting values are displayed. Furthermore, in the second mode, user information, which will be described later, may be displayed in addition to the setting code and its setting value.

Each value shown in FIG. 10A indicates a control parameter reallocated by the reallocation creation means 501 described with reference to FIG. 8B. The reallocation creation means 501 selects an appropriate value for the setting code of FIG. 7B from among the values shown in FIG. 7C based on the information input in step SB10 of FIG. 8B. For example, when terminal B1 is selected as an abnormal terminal by selecting selection section 807b1 shown in FIG. 9B and pressing terminal abnormality input button 809, the output assigned to setting code P13 corresponding to the terminal B1 is It is assigned to another terminal (here, terminal C1, which is set to no output). Specifically, in step SC, the reallocation creation means 501 changes the control parameters shown in (1) and (2) below from the example shown in FIG. 9A. (See Figure 7B and Figure 7C for the setting code and each value.)
(1) The value of setting code P13 was changed from "3" indicating full water to "999" indicating an abnormal terminal.
(2) The value of setting code P16 is changed from "0" indicating no output to "3" indicating full water.

The user information creation means 502 of the management device 310 creates user information to be displayed on the operation display section 80A of the external display 80 based on the reallocation control parameters. As an example, the user information creation means 502 creates a display of user information based on the reallocation control parameters, similar to FIG. 9A described above. Furthermore, the user information shown in FIG. 10B created by the user information creation means 502 and the user information display means 523 may include information indicating changes from the control parameters in the current water supply device 10. As a result, by making the external output to be changed more clear, it is possible to prevent the user from making a mistake in determining whether or not to make a change or making a connection mistake.

In the example shown in FIG. 10B, similarly to the example shown in FIG. 9B, a terminal graphic section 802, a wiring diagram graphic section 806, and a signal type character information section 808 are displayed on the operation display section 80A of the external display 80. . Note that explanations of parts that overlap with those in FIG. 9 will be omitted. In the example shown in FIG. 10, an abnormality display section 822 is also shown for an external display terminal in which an abnormality has occurred in the terminal graphic section 802. Specifically, here, since an abnormality has occurred in terminal B1, a double line is superimposed on the letters "B1" to indicate the abnormality. The abnormality display section 822 is displayed based on the user information received from the management device 310. That is, in this embodiment, the user information includes information indicating the external display terminal in which the abnormality has occurred.

Furthermore, in the example shown in FIG. 10B, the signal type character information section 808 also includes highlighted display sections 824 and 826, so that the input/output signal type that is newly changed by the reallocation is highlighted. Specifically, here, a double line (highlighted display section 824) is superimposed on the word "Full" indicating the full water signal output from terminal B1, indicating that the assignment will be deleted. The text "Full of water" indicating a new full-of-water signal output from the terminal C1 is highlighted with a thick frame (highlighted display section 826). Highlight display sections 824 and 826 are displayed based on the user information received from management device 310 in step SC24. The highlighted display parts 824 and 826 correspond to an example of what shows a change part from the control parameter in the current water supply apparatus 10. That is, in the present embodiment, the user information includes information indicating changes from the current control parameters in the water supply device 10. These highlighted display sections 824 and 826 allow the user to easily confirm the reassignment of input/output signal types.

FIG. 11 is a diagram showing an example of the display on the external display 80 at step SB80 in FIG. 8B. In FIG. 11, description of parts that overlap with FIG. 10B will be omitted. In FIG. 11, instead of the change confirmation button 830 and change cancel button 832 shown in FIG. 10B, a download button 840 for downloading user information and a print button 842 for printing user information are displayed. In this embodiment, as described with reference to FIG. 8, in the display at step SB30 (first display step) before the user confirms the control parameter change (step SB34), the user information is Downloading and/or printing is restricted. This allows the user to download, print, and refer to user information based on control parameters that have not actually been changed, thereby preventing the user from erroneously operating or wiring the water supply device 10. Then, in the display at step SB80 (second display step) after the user confirms the control parameter change (step SB34: Yes), a download button 840 and a print button 842 are displayed on the operation display section 80A, and the user Information can be downloaded and/or printed. This allows the user to save user information based on the determined control parameters in data or paper media.

Note that in the second mode display of the external display 80, the control parameter setting code and its value corresponding to the user information shown in FIG. 11 are also displayed. Specifically, the display shows the control parameter setting code and its value at step SB80 in FIG. 8B, and is, for example, the same display as in FIG. 10A.

FIG. 12 is a diagram showing an example of the display on the external display 80 in step S110 of FIG. 8B. In the example shown in FIG. 12, in the area above the operation display section 80A of the external display 80, there is a change date and time information section 871 that shows the date and time of the change in text information, and a worker information section 872 that shows the operator in text information. are also shown. In addition, the operation display section 80A shows a change information display section 873 that indicates the input of the terminal where the abnormality has occurred and the change of the input/output signal type using text information. Note that this information is preferably stored in the storage unit 366 by the change history creation means 512 of the management device 310. In the example shown in FIG. 12, in the area below the operation display section 80A, a graphic indicating the arrangement order of the signal types of each terminal in the I/O section 70 after the change, and letters indicating the input/output signal types after the change are displayed. Information is also displayed. In the example shown in FIG. 12, these displays use a terminal graphic section 802, a terminal type text information section 804, and a signal type text information section 808, similar to the example shown in FIG. 10B. Further, regarding the terminal B1 where an abnormality has occurred, the fact that an abnormality has occurred is highlighted and displayed in the abnormality display section 822. Similarly, in the subsequent display of the display state showing the state of the water supply device 10 on the external display 80, the abnormality display section 822 may be displayed. In this way, the user can recognize the abnormality of the terminal by looking at the display on the external display 80. Note that the display on the abnormality display section 822 by the external display 80 may be performed by referring to the failure history or maintenance history stored in the control memory 66, or may be performed by referring to the failure history or maintenance history stored in the control memory 66, or when an abnormality in the data table B has occurred. This may be done by referring to a setting value indicating .

Note that when displaying the change history, in the first mode, instead of displaying the changed setting code and its value, the changed terminal name and signal type are displayed in the change information display section, as shown in Figure 12. 873, and the setting code and its value changed in the second mode may be displayed.

In the system 1000 described above, when a predetermined change request is made, the control parameter to be changed (in the above example, the control parameter to be reassigned) and the user information based on the control parameter are stored in the management device 310. Then, user information based on the control parameters to be changed is displayed on the display section (in the above example, on the operation display section 80A of the external display 80). Thereby, when changing the settings of the control parameters, it is possible to indicate to the user the content that is likely to affect the user due to the setting change, and the user can easily deal with the impact of the setting change.

Furthermore, in the system 1000 described above, terminal abnormalities are input through the external display 80, and the management device 310 creates reassignments of input/output signal types based on the input information. Then, the control unit 65 of the water supply device 10 changes the input/output signal type based on the created reallocation. According to such a system 1000, if an abnormality occurs in a terminal in the I/O section 70, it can be easily dealt with.

Note that the control unit 65, external display 80, or management device 310 of the water supply device 10 in the system 1000 may be configured to be able to notify information regarding maintenance of the control unit 65. In this case, if a terminal abnormality is input (identified) or if the input/output signal type is changed by the control unit 65, it is determined that the next maintenance time will be earlier, and the maintenance time is set in the maintenance information. It is also possible to notify as follows. For example, if there is no abnormality in the terminal, the control unit 65 counts the time since the last replacement of the control unit 65 as the usage period, and the count is set to the first time (for example, 5 years). ) has elapsed, it is determined that the maintenance time has come, and a message is displayed on the display unit 72 to prompt replacement of the control unit 65. On the other hand, if a terminal abnormality occurs and the input/output signal type is changed, the control unit 65 counts the time since the previous replacement of the control unit 65 as the usage period, and the usage period is longer than the first time. When a second shorter period of time (for example, 3 years) has elapsed, it is determined that the maintenance period has come, and a message is displayed on the display unit 72 to prompt replacement of the control unit 65. With such a display, maintenance of the control unit 65 can be appropriately notified according to the actual status of the control unit 65.

As shown in FIG. 5A, the system 1000 includes an abnormal terminal identification unit 1002 for identifying a terminal in which an abnormality has occurred among a plurality of terminals of the I/O unit 70, and a reassignment unit 1002 for creating a reassignment of input/output signal types. A creation unit 1040 is provided. Note that in the example shown in FIG. 5A, the abnormal terminal identifying unit 1002 and the reassignment creating unit 1040 are provided in the management device 310, but the present invention is not limited to this example. That is, at least one of the abnormal terminal identification unit 1002 and the reassignment creation unit 1040 is provided in at least one of the external display device 80 and the water supply device 10 instead of or in addition to being provided in the management device 310. Good too.

Here, in the example shown in FIG. 8B, the communication unit 373 that receives abnormality information from the external display 80 and/or the calculation unit 369 that processes the received abnormality information correspond to the abnormal terminal identification unit 1002. Further, in the example shown in FIG. 8B, the calculation unit 369 and the like that execute the process of step SC3 correspond to the reallocation creation unit 1004. Note that the abnormal terminal identifying unit 1002 is not limited to identifying an abnormality in a terminal based on the input to the external display 80 by the user, but also identifies an abnormality in the terminal based on the input to the water supply device 10 or the management device 310. may be specified.

Furthermore, the abnormal terminal identification unit 1002 is not limited to identifying an abnormality in a terminal based on user input, and may be performed using a method shown in the following example in any of the water supply device 10, the external display 80, or the management device 310. Terminal abnormalities may be automatically identified. When automatically identifying an abnormality in a terminal, it is preferable that the identification of the abnormality functions as a request to change the control parameter.

As a first example of a method for automatically identifying terminal abnormalities in the system 1000, the output section 215 of the monitoring device 210 and the I/O section 70 of the water supply device 10 are connected by wire or wirelessly, and the monitoring device 210 A signal input from the water supply device 10 to the input unit 214 may be fed back to the water supply device 10. In this way, the water supply device 10 can determine whether the signal that it should have transmitted is correctly input to the monitoring device 210. Then, if the signal that the water supply device 10 should have transmitted and the signal fed back from the monitoring device 210 are different, the water supply device 10 can identify that an abnormality has occurred in the target terminal.

Further, as a second example of a method for automatically identifying terminal abnormalities in the system 1000, the monitoring device 210 transmits a signal input from the water supply device 10 to the input unit 214 to the external display device 280. Good too. The external display device 80 receives a signal (supposed to be output) from the I/O section 70 of the water supply device 10 from the water supply device 10, and transmits the signal input to the input section 214 of the monitoring device 210 to the external display device 80. 280. Thereby, the external display 80 can determine whether the signal that should be output from the water supply device 10 is correctly input to the monitoring device 210. Then, if the signal that is supposed to be output from the water supply device 10 and the signal that is input to the monitoring device 210 are different, the external display device 80 can specify that an abnormality has occurred in the target terminal.

Further, as a third example of a method for automatically identifying a terminal abnormality in the system 1000, the management device 310 transmits a signal that is (supposed to be) output from the I/O section 70 of the water supply device 10 to the water supply device 10. The signal received from the external display device 280 and input to the input unit 214 of the monitoring device 210 may be received from the external display device 280 . In this way, similar to the external display device 80 in the second example, the management device 310 can determine whether the signal that should be output from the water supply device 10 is correctly input to the monitoring device 210. , it is possible to identify that an abnormality has occurred in the target terminal.

(Modification 1)
FIG. 13A is a functional block diagram showing a modification of the system 1000 of the present embodiment described above. FIG. 13B is a diagram showing a modified example of the operation when resetting the control parameters in the system 1000 of the present embodiment described above. In FIGS. 13A and 13B, explanations that overlap with those in FIGS. 8A and 8B will be omitted.

In FIG. 8A, the management device 310 includes reassignment creation means 501 and user information creation means 502, and in FIG. 13A, the control unit 65 has them.

In FIG. 13B, when the abnormality information is input to the external display 80 (step SB10), the external display 80 transmits the abnormality information to the water supply device instead of or in addition to transmitting the abnormality information based on the abnormality input to the management device 310. 10 (step SB12A). Note that when the management device 310 receives the abnormality information, it is preferable that the management device 310 stores the abnormality information in the storage unit 366 and manages the abnormality information. When the water supply device 10 receives the abnormality information from the external display 80, it stores the abnormality information in the control memory 66 and creates control parameter reassignment based on the received abnormality information (step SA20A). ). The control unit 65 of the water supply device 10 may create reassignment of control parameters in the same manner as the process of the management device 310 in step SC20 of FIG. 8B described above. That is, specifically, the control unit 65 may exclude the terminal in which the abnormality has occurred based on the abnormality information from the external display 80 and create a reassignment of the input/output signal types of the plurality of terminals. Then, the control unit 65 of the water supply device 10 creates user information based on the created reallocation control parameters (step SA22A), and transmits the created user information to the external display 80 (step SA24A). Then, the external display device 80 stores the user information received from the water supply device 10 in the second storage means (step SB28).

Subsequently, the external display device 80 displays the user information stored in the second storage means on the operation display section 80A (step SB30), and when a change confirmation input is made (step SB34), the user information received from the water supply device 10 is displayed on the operation display section 80A (step SB30). A signal indicating the user information and change confirmation input is transmitted to the management device 310 (step SB36A). Management device 310 stores the change confirmation input in storage unit 366 (step SC40A), and transmits an approval signal to external display 80 (step SC42A). The external display 80 then transmits the received approval signal to the water supply device 10 (step SB50A), and the control parameters are changed in the water supply device 10 that has received the approval signal (step SA60).

In this way, a reassignment of control parameters may be made in the water supply device 10. Even in such an example, the same effects as the example described with reference to FIG. 8B can be achieved. Here, in the first modification, the control unit 65 of the water supply device 10 that executes the process of step SA20A corresponds to a "reallocation creation unit".

In the example shown in FIG. 13, when the user inputs the change confirmation (step SB34: Yes), information indicating the change confirmation is transmitted from the external display device 80 to the management device 310. However, without being limited to such an example, user information may be transmitted from the external display device 80 to the management device 310 instead of or in addition to the information indicating that the change is confirmed, or from the external display device 80 to the management device 310. Control parameters for reassignment may also be sent. When transmitting the reassignment control parameters from the external display device 80 to the management device 310, the reassignment control parameters may be transmitted together with the user information in step SA24A, or when the user confirms the change. The external display 80 may acquire the reallocation control parameters from the water supply device 10. Note that if user information or reassignment control parameters are sent from the external display device 80 to the management device 310 before the change is confirmed, the management device 310 will approve the change based on the transmitted user information or reassignment control parameters. It may also be determined whether or not to transmit a signal.

(Modification 2)
FIG. 14A is a functional block diagram showing a modification of the system 1000 of the present embodiment described above. FIG. 14B is a diagram showing a modified example of the operation when resetting the control parameters in the system 1000 of the present embodiment described above. In FIGS. 14A and 14B, explanations that overlap with those in FIGS. 8A and 8B will be omitted.

In FIG. 8A, the management device 310 includes reassignment creation means 501 and user information creation means 502, and in FIG. 14A, the external display device 80 has them.

In FIG. 14, when abnormality information is input to external display 80 (step SB10), external display 80 creates control parameter reassignment based on the input information (step SB20B). It is preferable that the external display device 80 creates the reassignment of the control parameters, similar to the process of the management device 310 in step SC20 of FIG. 8B described above. That is, specifically, the external display device 80 may exclude the terminal input by the user in which the abnormality has occurred, and create a reassignment of the input/output signal types of the plurality of terminals. Then, the external display device 80 creates user information based on the created reallocation control parameters (step SB22B), and stores the created user information in the second storage means (step SB28). Next, the external display device 80 displays the user information stored in the second storage means on the operation display section 80A (step SB30), and when a change confirmation input is made (step SB34), the created reassignment control is performed. The parameters and change confirmation input are transmitted to the management device 310 (step SB40B). The management device 310 stores the received reallocation control parameters and change confirmation input in the storage unit 366 (step SC40B). Then, when an approval signal is transmitted from the management device 310 to the external display device 80 (step SC42B), control parameters for reassignment are transmitted from the external display device 80 to the water supply device 10, similar to the operation shown in FIG. 8B ( Step SB50), the input/output signal type is changed in the water supply device 10 (step SA60). Note that when the management device 310 receives the reassignment control parameters and the change confirmation input from the external display device 80, it is preferable to check whether there are any problems with the reassignment control parameters and send an approval signal.

In this manner, reassignments of control parameters may be made at external display 80. Even in such an example, the same effects as the example described with reference to FIGS. 8A and 8B can be achieved. Here, in the second modification, the external display device 80 that executes the process of step SB20B corresponds to a "reassignment creation unit".

(Modification 3)
In the system 1000 described above, the water supply device 10 is configured to be able to communicate with the management device 310 through the external display device 80, but the invention is not limited to this example. 310 may be configured to be capable of direct communication.

FIG. 15A is a functional block diagram showing a modification of the system 1000 of the present embodiment described above. FIG. 15B is a diagram illustrating an example of an operation when resetting control parameters in such a modified system 1000.

In FIG. 8A, the control unit 65 communicates with the management device 310 via the external display 80 (and the network 300), but in FIG. 15A, the control unit 65 can communicate directly with the management device 310 via the network 300. Connected. Note that also in the examples of FIGS. 13A and 14A, the control unit 65 may be directly communicably connected to the management device 310 via the network 300.

The example shown in FIG. 15B is generally the same as the example shown in FIG. 8B, and step SC42C is executed instead of steps SC42 and SB50 of the example shown in FIG. 8B, and step SA64C is executed instead of step SB70. That is, when the management device 310 receives the change confirmation input from the external display 80 (step SB36) and converts the reassignment control parameters into transmission data (step SC40), the management device 310 transmits the reassignment control parameters to the water supply device 10. Transmit directly (step SC42C). The water supply device 10 that has received the reallocated control parameters changes the control parameters (step SA60), transmits a change completion signal indicating completion of the control parameter change to the external display 80 (step SA62), and also sends a change completion signal to the management device 310 (step SA62). (step SA64C). In this way, by directly transmitting the control parameters for reassignment from the management device 310 to the water supply device 10, it is possible to prevent unintended or unauthorized setting changes of the water supply device 10 by the external display device 80.

(Modification 4)
In the system 1000 described above, user information based on control parameters is displayed on the operation display section 80A of the external display 80. However, the user information may be displayed on at least one of the display section 72 of the control section 65, the display section 380 of the management device 310, and the external display 280 instead of or in addition to the operation display section 80A. . Furthermore, the display and/or change in the first mode can be executed on all of the external display 80, the display section 72 of the control section 65, the display section 380 of the management device 310, and the external display 280, and The display and/or change in mode can be performed on any of the external display 80, the display 72 of the control unit 65, the display 380 of the management device 310, and the external display 280 (for example, only the display 72 and the display 380). ) may be executable.

(Modification 5)
FIG. 16 is a diagram showing a modification of the display in step SB30 (first display step) in FIG. 8B by the external display 80. In addition, in FIG. 16, the operation display section 80A is horizontally elongated, but it goes without saying that the aspect ratio of the operation display section 80A is arbitrary. In the example shown in FIG. 16, a user information display section 910 before the change shows user information based on the current control parameters of the control unit 65, and a user information display section 920 after the change shows user information based on the reallocation control parameters. are also shown on the operation display section 80A. Here, the before-change user information display section 910 is the same as the user information display in FIG. 9B, and the after-change user information display section 920 is the same as the user information display in FIG. 10B. Regarding the before-change user information display section 910 and the after-change user information display section 920, explanations that overlap with those in FIGS. 9B and 10B will be omitted.

In the example shown in FIG. 16, the pre-change user information display section 910 and the post-change user information display section 920 each indicate the current (pre-change) user information and the post-change user information using text information. A character information section 930 shown is shown on the operation display section 80A. In this way, by displaying the pre-change user information display section 910 and the after-change user information display section 920 together with the operation display section 80A, the user can more easily recognize changes due to changes in control parameters. can.

In the example shown in FIG. 16, similarly to the example shown in FIG. 10B, a change confirmation button 830 and a change cancel button 832 are shown on the operation display section 80A. Further, in the example shown in FIG. 16, a change option button 834 for the user to select an option when changing the control parameter is shown on the operation display section 80A. This change option button 834 is an example of an option input means by which the user can add options associated with changing control parameters.

When the change option button 834 is operated by the user, as shown in the lower part of FIG. It is preferable to display it on the display section 80A. As an example, the option information is created by the user information creation means 502 based on the reallocation control parameters and transmitted to the external display 80, similar to the user information described above. As an example, the user information creation unit 502 can generate option information corresponding to the control parameter to be reassigned by referring to a data table in which control parameters and option information are associated with each other, which is stored in advance in the storage unit 366 of the management device 310. Create. In the example shown in FIG. 16, the operator can select whether or not to request the operator to change the control parameters and to connect the wiring after changing the control parameters as an additional option that can be selected by the operator. This allows the operator to determine whether to confirm the change in the control parameters by himself or herself and select whether to make the wiring connection or to ask a worker to do so. Note that when changing control parameters is selected as an item to be requested to the worker, the change confirmation button 830 may be disabled. Thereby, it is possible to prevent the operator from inputting the final control parameters even though the operator has been requested to change the control parameters.

FIG. 17 shows a selection flow of the change confirmation button 830, change cancel button 832, or change option button 834 on the external display 80. This selection flow is performed, for example, when step SB30 in FIG. 8B is being executed on the external display 80. For example, when a user selection is made (step S220) while the external display device 80 is displaying as shown in FIG. 10B (step S210), the external display 80 executes a process in accordance with the user selection.

For example, when the user selects the change cancel button 832 (step S220: "change cancel"), the external display 80 does not finalize the reassigned control parameters, that is, the first storage area of the control unit 65 A process of returning the display of the operation display section 80A to a predetermined initial screen is executed without changing the control parameters stored in the control parameter 66a (step S230). Thereby, when the user does not wish to change the control parameters, the change in the control parameters can be canceled.

Further, when the change option button 834 is selected by the user (step S220: "Change option"), the external display 80 displays a message when the user changes the control parameters, as described with reference to FIG. 16. Information for selecting an option (option information) may be displayed on the operation display section 80A. Then, when the change confirmation button 830 is operated by the operator with the selection to request a worker made, the external display 80 sends a signal to the management device 310 indicating that a work request has been made to the worker. It is preferable to transmit it (step S240). Furthermore, the management device 310 may store information about option selections made by the user in the storage unit 366. Although not shown in FIG. 17, the configuration may be such that selection of an option can be canceled when option information is displayed on the operation display section 80A. If the option selection is canceled, the process may return to the initial screen and terminate the flow shown in FIG. 17, or may return to step S210.

Further, when the change confirmation button 830 is selected by the user (step S220: "change confirmation process"), the external display 80 executes a change confirmation process to confirm the reassigned control parameters (step S250), End the flow. A specific example of the change confirmation process is the process from step SB36 in FIG. 8B described above. Through the change confirmation process, the control parameters stored in the first storage area 66a of the control unit 65 are updated to the reallocated control parameters.

In this way, in the flow shown in FIG. 17, either the change option button 834 or the change confirmation button 830 is configured to be selectable. In other words, the optional input that allows the user to request work associated with changing the control parameters and the final input that allows the user to confirm whether or not to change the control parameters are configured such that either one can be selected. Ru. When the change option button 834 is selected, the change confirmation button 830 may be disabled. This can prevent the operator from performing incorrect operations.

As described above, the management device 310 manages various information such as the installation location, contact information, owner, administrator, control parameter change history, operation history, failure history, and work history for each water supply device 10, and It has information on the workers that can be dispatched for each region (scope of dispatch of workers, level of learning of workers, product groups that can be worked on, etc.). Therefore, when the management device 310 receives a signal indicating that a work request has been made to a worker from the external display device 80 according to the option settings, the management device 310 stores the requested work details, the installation location of the water supply device 10, and the worker information. A worker is selected based on the selected worker, and a work request is made to the selected worker with the control parameters for reassignment, user information based on the control parameters, and change history of the control parameters attached. This allows workers to understand the work details before heading to the site, thereby reducing work time.

Further, as described above, when a terminal abnormality is input (identified) or when the input/output signal type is changed by the control unit 65, the management device 310 determines that the next maintenance time is early. to decide. In other words, the management device 310 determines when to maintain the control unit 65 in accordance with changes in control parameters. When dispatching a worker to a water supply device 10 whose maintenance time is within a predetermined range, the management device 310 notifies the worker of the determined maintenance time and the current usage period count at the time of requesting the work. As a result, the notified operator can propose and/or carry out maintenance, thereby preventing abnormalities from occurring.

Note that although the above description has been made regarding the user information when changing the signal type, the user information group possessed by the user information creation means also includes user information regarding other control parameters related to operation and failure. As an example of the user information included in the user information group, user information associated with the control parameters A10 to A13 related to the inflow pressure reduction described in the description of FIG. 3 will be described here. The control parameter setting codes A10 to A13 and the user information corresponding to their values are: "If the inflow pressure is 7 mAq or less and 10 seconds have elapsed, a low inflow state will occur." "After the inflow pressure has decreased, the inflow pressure will be 10 mAq or more. After 15 seconds have elapsed, the inflow pressure drop state will be resolved.'' may be text information, or the values of setting codes A10 to A13 may be written on a graph where the horizontal axis is time and the vertical axis is inflow pressure. .
