Description

Field machine

The present invention relates to a field machine, and more particularly, to a field machine that connects a plurality of displays to a body portion.

In order to be able to operate the machine from multiple places, a plurality of displays installed in multiple places may be connected to one machine. When different operators operate multiple displays at the same time and the operation result of the first operator affects the operation status of the second operator, it is possible that the second operator misunderstands that the display or the machine is malfunctioning, which may consume the originally unnecessary work time.

In order to prevent such misunderstanding, there are methods for restricting operations that affect the state of the machine such as parameter setting to only one display, and making other displays only show the state of the machine. Regarding the method of limiting the display, there are a method of designating one display in advance, and a method of limiting one display to be operated first and starting another operation after the operation is completed. For example, in a plant monitoring and control device disclosed in Patent Document 1, a plant machine can be operated from any one of a plurality of operation input devices, but cannot be performed from another operation input device in an operation using one operation input device. operating.

However, the conventional method has the following problems (I) to (III). (I) The operable display is limited to one, so it cannot be operated from multiple places simultaneously. (II) In the case of a method in which one monitor is specified in advance, operations cannot be performed from other monitors. (III) In the case of the method of switching the operable display, the control of the switching becomes complicated, and there is a high possibility that the switching cannot be performed correctly for some reason.

Hereinafter, a conventional example is used to explain a conventional problem. Here, an explanation will be given by taking an adjustment meter as an example. FIG. 24 is a block diagram showing a configuration of a main body portion of a conventional regulator. In FIG. 24, only the structure related to the display 101A and the display 101B of the structure of the main body 100 of the adjustment meter is shown, and the structure related to the measurement, control, and operation terminal (external device) operation of the adjustment meter is not shown. . The data of the measurement, control and operation status of the regulator (external device) and the parameters of the main body unit 100 are stored in the main body information storage unit 10.

<Example 1-1> With reference to FIG. 25, an example of an operation when the control amount PV, the set value SP, the operation amount MV, and the state of the display 101B are displayed on the display 101A in the adjustment meter will be described. The control amount PV (process amount) is measurement data (for example, temperature measurement value), the set value SP is control data (for example, temperature setting value), and the operation amount MV is data for operation at the operating end. As a matter of course, the control object is controlled using the manipulated variable MV output from the control object.

Among the display states of the display 101A and the display 101B, there are a state in which a monitoring screen for monitoring the state of the main body section 100 is displayed by a user, and a state in which a parameter setting screen for changing or confirming parameters of the main body section 100 is displayed by a user. .

The ontology information processing section 11 receives the control amount PV from the measurement processing section (not shown) of the main body section 100 and stores it in the ontology information storage section 10 (step S1000 in FIG. 25).

The communication request acceptance processing unit 14 receives an update request of the status information of the display 101A from the communication message processing unit 13A, and transmits the update request to the display information processing unit 15 (step S1006 in FIG. 25). The display information processing unit 15 that has accepted this update request updates the status information of the display 101A stored in the display information storage unit 16 (step S1007 in FIG. 25).

The display information processing section 15 takes out the status information of the display 101A from the display information storage section 16 and passes it to the communication information providing processing section 12 (step S1008 in FIG. 25). The communication information providing processing section 12 transmits the control amount PV, the set value SP and the operation amount MV received from the main body information processing section 11 and the status information of the display 101A received from the display information processing section 15 to the communication message processing section 13B (FIG. 25 Step S1009).

The communication message processing unit 13B receives the control information PV, the set value SP, the operation value MV, and the status information of the display 101A from the communication information providing processing unit 12, and generates a communication message including these information (step S1010 in FIG. 25), The communication message is sent to the display 101B (step S1011 in FIG. 25).

<Example 1-3> Next, an example of the operation when the user operates the display 101A in the adjustment meter to set the set value SP to a value of 100 will be described with reference to FIG. 26. There are many parameters in the adjusting meter, and the set value SP as the control data is also a kind of parameter.

The communication message processing unit 13A receives a communication message with the set value SP set to 100 from the display 101A (step S1100 in FIG. 26), interprets the communication message, and generates a setting request for setting the set value SP to 100 (step S1101 in FIG. 26). ). The communication request acceptance processing unit 14 receives a setting request from the communication message processing unit 13A, and transmits the request to the main body information processing unit 11 (step S1102 in FIG. 26). The body information processing unit 11 that has accepted the setting request sets the setting value SP stored in the body information storage unit 10 to 100 (step S1103 in FIG. 26).

<Example 1-4> Next, an example of an operation when the user operates the display 101B in the adjustment meter and sets the set value SP to a value of 100 will be described. The flow of processing is the same as in the case of Example 1-3, and therefore, the symbols in FIG. 26 will be used for explanation.

The communication message processing unit 13B receives a communication message with the set value SP set to 100 from the display 101B (step S1100 in FIG. 26), interprets the communication message, and generates a setting request to set the set value SP to 100 (step S1101 in FIG. 26). ). The communication request acceptance processing unit 14 and the body information processing unit 11 operate in the same manner as in Example 1-3 (steps S1102 and S1103 in FIG. 26).

FIG. 27 is a block diagram showing a configuration of a conventional display 101A. Although the configuration of the display 101A is shown in FIG. 27, the configuration of the display 101B is the same as that of the display 101A.

<Example 2-1> An example of the operation when the monitoring screen is displayed on the display 101A in the adjustment meter will be described with reference to FIG. 28. On the monitoring screen of the display 101A, the control amount PV, the set value SP, the operation amount MV, and the state of the display 101B are displayed.

The communication message processing section 20 of the display 101A receives a communication message indicating the state of the body section 100 from the body section 100 (step S1200 in FIG. 28), interprets the communication message, and extracts a message including the control amount PV, the set value SP, and the operation amount MV. The status information of the main body unit 100 is transmitted to the main body information processing unit 21 of the display 101A (step S1201 in FIG. 28). The body information processing unit 21 of the display 101A stores the received state information of the body unit 100 in the body information storage unit 22 of the display 101A (step S1202 in FIG. 28).

Further, the communication message processing unit 20 of the display 101A receives a communication message indicating the status of the display 101B from the main body 100 (step S1203 in FIG. 28), interprets the communication message, takes out the status information of the display 101B, and transmits it to the display of the display 101A. The information processing unit 23 (step S1204 in FIG. 28). The display information processing unit 23 of the display 101A stores the received status information of the display 101B in the display information storage unit 24 of the display 101A (step S1205 in FIG. 28).

On the monitor screen of the display 101A, there are a first display area that displays the values of the control amount PV, the set value SP, and an operation amount MV, a second display area that shows the status of the display 101B, and a third display that displays buttons and the like described later. region.

The screen control processing section 25 of the display 101A reads the control amount PV, the set value SP, and the operation amount MV from the main body information storage section 22, and reads the status information of the display 101B from the display information storage section 24 to generate screen display data The information is transmitted to the display processing unit 26 of the display 101A. The screen display data is used to display the control amount PV, the set value SP, and the operation amount MV in the first display area, and the state of the display 101B in the second display area. And a button type described later is displayed in the third display area (step S1206 in FIG. 28).

The display processing unit 26 of the display 101A controls the liquid crystal display 27 in accordance with the received screen display data. Accordingly, the control amount PV, the set value SP, and the operation amount MV are displayed in the first display area of the screen of the liquid crystal display 27 of the display 101A, the state of the display 101B is displayed in the second display area, and the third display is displayed in the third display area. Buttons are displayed in the area (step S1207 in FIG. 28).

<Example 2-2> Next, an example of an operation of transmitting state information of the display 101A from the display 101A to the main body 100 in the adjustment meter will be described with reference to FIG. 29. The screen control processing unit 25 of the display 101A notifies the state of the screen of the liquid crystal display 27 to the display information processing unit 23 of the display 101A (step S1300 in FIG. 29).

The display information processing unit 23 that has received the notification generates status information of the display 101A (step S1301 in FIG. 29), and transmits the generated status information to the communication message processing unit 20 of the display 101A (step S1302 in FIG. 29). The communication message processing unit 20 that has received the status information creates a communication message indicating the status of the display 101A (step S1303 in FIG. 29), and sends the created communication message to the main body unit 100 (step S1304 in FIG. 29). The operation of transmitting the status information of the display 101B from the display 101B to the main body section 100 is the same as the operation described above with reference to FIG. 29.

<Example 2-3> Next, an example of an operation when the parameter setting screen is displayed on the display 101A in the adjustment meter will be described with reference to FIG. 30. On the parameter setting screen of the display 101A, the parameter setting value and the state of the display 101B are displayed.

The screen control processing section 25 of the display 101A requests the parameter processing section 28 of the display 101A to acquire a parameter setting value (step S1400 in FIG. 30). The parameter processing unit 28 of the display 101A transmits a request for acquiring a set value of the parameter to the communication message processing unit 20 of the display 101A (step S1401 in FIG. 30). The communication message processing unit 20 of the display 101A creates a communication message requesting a set value of a parameter (step S1402 in FIG. 30), and sends the created communication message to the main body unit 100 (step S1403 in FIG. 30).

When the communication message processing unit 20 of the display 101A receives a communication message indicating the setting value of a parameter from the main body 100 (YES in step S1404 in FIG. 30), it interprets the communication message, extracts the setting value of the parameter, and transmits it to the display 101A. The parameter processing unit 28 (step S1405 in FIG. 30). The parameter processing section 28 of the display 101A stores the set values of the received parameters in the parameter storage section 29 of the display 101A (step S1406 in FIG. 30).

Further, the communication message processing unit 20 of the display 101A receives a communication message indicating the status of the display 101B from the main body 100 (step S1407 in FIG. 30), interprets the communication message, takes out the status information of the display 101B, and transmits it to the display of the display 101A The information processing unit 23 (step S1408 in FIG. 30). The display information processing unit 23 of the display 101A stores the received status information of the display 101B in the display information storage unit 24 of the display 101A (step S1409 in FIG. 30).

In the parameter setting screen of the display 101A, there are a first display area that displays the set value of the parameter, a second display area that displays the state of the display 101B, and a third display area that displays buttons and the like described later.

The screen control processing section 25 of the display 101A reads the parameter setting values from the parameter storage section 29, and reads the status information of the display 101B from the display information storage section 24, generates screen display data, and transmits the data to the display processing section 26 of the display 101A. The screen display data is used to display the name or number of the parameter used to identify the parameter and the set value of the parameter in the first display area, the status of the display 101B in the second display area, and the later-mentioned Buttons are displayed in the third display area (step S1410 in FIG. 30).

The display processing unit 26 of the display 101A controls the liquid crystal display 27 in accordance with the received screen display data. As a result, the parameter setting value is displayed in the first display area of the screen of the liquid crystal display 27 of the display 101A, the state of the display 101B is displayed in the second display area, and the buttons and the like are displayed in the third display area (Fig. Step S1411 of 30). The operation of displaying the parameter setting screen on the display 101B is the same as the operation described above with reference to FIG. 30.

Next, the liquid crystal display 27 and the touch sensor 30 of the displays 101A and 101B will be described. In the following example, the display 101A is described, but the configuration of the display 101B is the same as that of the display 101A. When the display 101A is viewed from the front, as shown in FIG. 31, there are an area where the touch sensor 30 is arranged on the surface of the liquid crystal display 27 and a bezel 2012 surrounding these.

The display 101A displays digits, characters, and graphics on the liquid crystal display 27. Further, the display 101A displays a graphic of a button on the liquid crystal display 27, and when the touch sensor 30 detects that the vicinity of the graphic of the button is pressed, it is interpreted that the button is pressed to operate. FIG. 32 is a diagram showing button operations and screen transitions on the display 101A.

<Example 3-1> An example of a monitoring screen displayed on the display 101A will be described. Since it is a monitor screen, the display of the screen switch button is as shown in FIG. 33, which means that the MONI button 2020 of the monitor screen becomes the selection state of white characters on a black background, and the PARA button 2021 of the parameter setting becomes a black character on a white background Non-selected state. On the monitoring screen, each value of the control amount PV, the set value SP, and the operation amount MV is displayed as the status information of the main body portion 100.

Further, status information 2022 of the display 101B is displayed at the lowermost part of the monitoring screen. In the example of FIG. 33, “HMI-B” which means the display 101B and “Monitoring” which means the monitoring screen are displayed, and thus it is known that the monitor 101B is displaying the monitoring screen. Therefore, the user viewing the monitoring screen of the display 101A knows that the parameter setting operation is not performed on the display 101B, and therefore, even if the parameter setting operation is performed on the display 101A, the operations will not conflict.

<Example 3-2> Next, another example of a monitoring screen displayed on the display 101A will be described. In the example of FIG. 34, as the status information 2022 of the display 101B displayed on the lowermost part of the monitoring screen, "HMI-B" which means the display 101B and "Para setting" which means the parameter setting screen are displayed, Therefore, it is known that the display 101B is displaying a parameter setting screen. Therefore, the user viewing the monitoring screen of the display 101A knows that the parameter setting operation is being performed on the display 101B. Therefore, if the parameter setting operation is performed on the display 101A, there is a possibility that the operation conflicts.

<Example 3-3> Next, an example of an operation when the monitor screen of the display 101A is switched to the parameter setting screen will be described. When the user presses the PARA button 2021 while the monitor screen is displayed on the display 101A as shown in FIG. 33, a parameter setting screen as shown in FIG. 35 (transition of 300 in FIG. 32) is performed.

Because it is a parameter setting screen, the display of the screen switching button means that the MONI button 2020 of the monitoring screen becomes a non-selected state of black characters on a white background, and the parameter setting PARA button 2021 becomes a selected state of white characters on a black background. In the parameter setting screen, a parameter value is displayed from a plurality of parameters. In the example of FIG. 35, the value of the set value SP as a parameter is displayed.

In the parameter setting screen, as a button for setting operation, a left arrow (←) button 2023 for displaying the setting value of the previous parameter and a right arrow (→) button for displaying the setting value of the next parameter are displayed. 2024, and a Change button 2025 for displaying a parameter setting change screen.

Further, at the bottom of the parameter setting screen, status information 2022 of the display 101B is displayed. In the example of FIG. 35, "HMI-B" which means the display 101B and "monitoring" which means the monitoring screen are displayed, and it is known that the display 101B is displaying the monitoring screen. Therefore, a user viewing the parameter setting screen of the display 101A knows that the parameter setting operation is not performed on the display 101B, and therefore, even if the parameter setting operation is performed on the display 101A, the operations do not conflict.

<Example 3-4> Next, an example of a parameter setting change screen displayed on the display 101A will be described. When the user presses the change button 2025 while the parameter setting screen is displayed on the display 101A as shown in FIG. 35, the parameter setting changing screen as shown in FIG. 36 is changed (transition of 301 in FIG. 32). Here, since the set value SP is displayed in the state of FIG. 35, it is a parameter setting change screen for changing the set value SP.

The parameter setting change screen displays a numerical value of a parameter for setting a change object and a plurality of buttons called a ten key. In the keypad, there are digit buttons 2026, "0" to "9", decimal point button 2027, reverse button 2028 to reverse the sign, C button 2029 to delete all the inputs, and the last button to delete the last input. The BS button 2030, the ENT button 2031 for completing the input and returning to the parameter setting screen, and the CAN button 2032 for canceling the input and returning to the parameter setting screen.

When the user presses the ENT button 2031 or the CAN button 2032 while the parameter setting change screen is displayed on the display 101A as shown in FIG. 36, the parameter setting screen is displayed (transition of 302 in FIG. 32). When the user presses the MONI button 2020 while the parameter setting screen is displayed on the display 101A, the monitor screen is displayed (transition of 303 in FIG. 32).

An example of the operation when the parameter setting change screen is displayed on the display 101A will be described with reference to FIG. 37. The screen control processing unit 25 of the display 101A generates screen display data for displaying the buttons and the like shown in FIG. 36 and transmits the data to the display processing unit 26 of the display 101A (step S1500 in FIG. 37). The display processing unit 26 of the display 101A controls the liquid crystal display 27 in accordance with the received screen display data. Thereby, the parameter setting change screen as shown in FIG. 36 is displayed on the display 101A (step S1501 of FIG. 37).

The screen control processing unit 25 of the display 101A generates screen display data in which the value of a parameter is changed in accordance with a user's operation of the buttons 2026 to 2030 (steps S1502 and S1503 in FIG. 37). The display processing unit 26 of the display 101A controls the liquid crystal display 27 in accordance with the received screen display data. Thereby, the numerical value of the parameter of the setting change object displayed on the parameter setting change screen is changed (step S1504 of FIG. 37).

Until the user presses the ENT button 2031 or the CAN button 2032, the processes of steps S1502 to S1504 are repeatedly executed. When the user presses the ENT button 2031 (YES in step S1505 of FIG. 37), the screen control processing section 25 of the display 101A transmits the value of the parameter after the setting is changed to the parameter processing section 28 of the display 101A. The parameter processing unit 28 changes the numerical value of the parameter stored in the parameter storage unit 29 of the display 101A (step S1506 in FIG. 37). Then, the parameter processing section 28 notifies the main body section 100 of the value of the parameter after the setting is changed, and transmits it to the communication message processing section 20 of the display 101A.

The communication message processing unit 20 of the display 101A creates a communication message indicating the numerical value of the parameter after the setting is changed (step S1507 in FIG. 37), and sends the created communication message to the main unit 100 (step S1508 in FIG. 37). Then, the screen control processing unit 25 of the display 101A displays a parameter setting screen (step S1509 in FIG. 37).

When the user presses the CAN button 2032 (YES in step S1510 in FIG. 37), the screen control processing unit 25 of the display 101A displays the parameter setting screen without changing the parameters (step S1509 in FIG. 37).

In the example shown in FIG. 36, the small-sized liquid crystal display 27 has a narrow display area. If the keypad is displayed, the remaining space is insufficient, and other display states are not displayed. However, it takes a short time to change the parameter setting. When the parameter setting change is completed, it returns to the parameter setting screen or monitoring screen to display the status of other displays, which rarely causes a major problem. The large-sized liquid crystal display 27 can display the status of other displays.

As described above, for the existing regulator, a user viewing one display can recognize whether the status of the other display is a monitoring screen or a parameter setting screen. In some cases, the adjustment meter may have a lock function such that a display cannot display a parameter setting screen while a display is displaying a parameter setting screen or a parameter setting changing screen. At this time, the user can view the status information of other displays and know the reason why the display that they operate does not become the parameter setting screen, and the lock function can be released if necessary.

However, in order to release the lock function, one of the following measures is required: (a) go to the display where the parameter setting screen is being displayed, meet the operator of this display and delegate to switch to the monitoring screen; (b) use the telephone or electronic Mail and the like contact the operator of the display that is displaying the parameter setting screen and request to switch to the monitoring screen; (c) Forcibly set the display that is displaying the parameter setting screen to the monitoring screen.

In order to implement (a), it is necessary to go to the display where the parameter setting screen is displayed. In the case where this display is located at a distant place, much time is required. It is difficult to implement (a) without going to where this display is located.

(B) Measures Although it is not necessary to go to the display where the parameter setting screen is displayed, the operator of this display needs to be identified and contacted. When the operator cannot be identified, the candidate of the operator needs to be contacted to determine the operator. It is difficult to implement (b) without an operator.

(C) Measures need to improve other methods such as forcibly setting other monitors to monitor screens, so the operation sequence of the monitors becomes complicated, and the design of the hardware or software of the monitors becomes complicated.

When the adjustment meter does not have the lock function, the user can view status information of other displays and recognize the possibility of conflicting operation of parameter setting. In order to avoid conflicts, any of the following measures are required: (α) go to the display where the parameter setting screen is being displayed, meet with the operator of this display and decide how to avoid conflicts; (β) use telephone or email to communicate with The operator of the display that is displaying the parameter setting screen contacts to determine how to avoid conflicts; (γ) Forcibly sets the display that is displaying the parameter setting screen to the monitoring screen. The problems of (α) measure, (β) measure, and (γ) measure are the same as those when the regulator has a lock function. In addition, the above problems also occur for field devices other than regulators. [Prior Art Literature] [Patent Literature]

[Examples] Hereinafter, examples of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing a connection method of a regulator in this embodiment. In the example of FIG. 1, two displays 2A and 2B are connected to one body portion 1. The main body unit 1 performs measurement (input processing), control (calculation processing), and operator-side operation (output processing). The user monitors the state of the main body unit 1 by viewing the screen of the display 2A or the display 2B, and operates the display 2A or 2B to set the parameters of the main body unit 1. The main body portion 1 is connected to the display 2A and the display 2B through communication signal lines 3A and 3B of a separate system. It is also possible to connect three or more displays to the main body section 1, but the main body section 1 requires the same number of communication ports as the display connected to the main body section 1.

FIG. 2 is a diagram showing another connection method of the regulator in this embodiment. In the example of FIG. 2, four displays 2A, 2B, 2C, and 2D are connected to one main body unit 1 through a communication signal line 3 of a system. In this example, a communication port is required in the main body portion 1.

The present invention can be applied to any of the connection modes of FIGS. 1 and 2. Further, the main body portion and the display may be connected via a wireless line instead of a communication signal line. Therefore, the following description is not limited to the connection method between the main body portion and the display. Moreover, in this embodiment, a case where there are two displays is described, but three or more displays may be used.

FIG. 3 is a block diagram showing the configuration of the main body unit 1 of the adjustment meter of the present embodiment, and the same configuration as in FIG. 24 is denoted by the same reference numeral. The main body unit 1 includes a main body information storage unit 10, a main body information processing unit 11, a communication information providing processing unit 12, a communication message processing unit 13A, a communication message processing unit 13B, a communication request acceptance processing unit 14, a display information processing unit 15, and display information.

As before, data (control amount PV, set value SP, operation amount MV) of the measurement, control, and operation side (external device) operation of the regulator and parameters of the main body unit 1 are stored in the main body information storage unit 10 . As is well known, the operation-side operation processing unit (not shown) of the main body unit 1 calculates the operation amount MV based on the control amount PV and the set value SP. As a matter of course, the control object is controlled using the manipulated variable MV output from the control object.

In this embodiment, an inter-display coordination processing unit 17 is added to the existing adjustment meter to perform processing of information between the display 2A and the display 2B. In addition, although the status information or requirements of the display of the related art are transmitted through the display coordination processing unit 17, the display information processing unit 15 stores or retrieves the display information storage unit 16 in the same manner as the conventional technology.

<Example 4-1> Next, an example of an operation when the information from the display 2B is displayed on the display 2A in the adjustment meter of the present embodiment will be described with reference to FIG. 4. The types of information between displays are WHO, IAM, TEL, and QUIT.

WHO asks users who are monitoring or operating other displays to ask who the person is. IAM is a response message that indicates to the user who is monitoring or operating other displays by sending the user's own identification (ID).

TEL is a request message that sends a user's own phone number to a user who is monitoring or operating another display to call himself. QUIT is a request message for a user who is currently operating another display to suspend operation. In addition, each message includes the identifier of the display of the source and the identifier of the target display.

When the communication message processing unit 13B receives a communication message containing information from the display 2B to the display 2A (step S100 in FIG. 4), it interprets the communication message and extracts the information to generate a display request for the information sent from the display 2B to the display 2A ( Step S101 in FIG. 4).

The communication request acceptance processing unit 14 receives the information display request generated by the communication message processing unit 13B, and transmits the information display request to the inter-display coordination processing unit 17 (step S102 in FIG. 4). In order to forward the information sent from the display 2B to the target display 2A, the inter-display coordination processing unit 17 transmits the information display request sent from the communication request acceptance processing unit 14 to the communication information providing processing unit 12 (step S103 in FIG. 4). ). The communication information providing processing unit 12 transmits the information display request to the communication message processing unit 13A corresponding to the destination of the information (step S104 in FIG. 4).

When the communication message processing unit 13A receives an information display request from the communication information providing processing unit 12, it creates a communication message including the information sent from the display 2B to the display 2A (step S105 in FIG. 4), and sends the created communication message to Display 2A (step S106 in FIG. 4).

<Example 4-2> Next, an example of an operation when the information from the display 2A is displayed on the display 2B in the adjustment meter of the present embodiment will be described. The flow of processing is the same as in the case of Example 4-1, and therefore the description is given using the symbols in FIG. 4.

When the communication message processing unit 13A receives a communication message containing information from the display 2A to the display 2B (step S100 in FIG. 4), it interprets the communication message and extracts the information to generate a display request for the information sent from the display 2A to the display 2B ( Step S101 in FIG. 4).

The communication request acceptance processing unit 14 receives the information display request generated by the communication message processing unit 13A, and passes the information display request to the inter-display coordination processing unit 17 (step S102 in FIG. 4). The inter-display coordination processing unit 17 passes this information display request to the communication information providing processing unit 12 (step S103 in FIG. 4). The communication information providing processing section 12 transmits this information display request to the communication message processing section 13B corresponding to the destination of the information (step S104 in FIG. 4).

When the communication message processing unit 13B receives an information display request from the communication information providing processing unit 12, it creates a communication message including information sent from the display 2A to the display 2B (step S105 in FIG. 4), and sends the created communication message to Display 2B (step S106 in FIG. 4).

The structure of the body portion 1 shown in FIG. 3 corresponds to the connection manner shown in FIG. 1. The structure of the main body part 1 corresponding to the connection method shown in FIG. 2 is shown in FIG. 5. In the configuration of the main body unit 1 shown in FIG. 5, a communication transmission / reception processing unit 18 is added to the configuration shown in FIG. 3.

The communication transmission / reception processing unit 18 sends a communication message to be transmitted from the display 2A to the main unit 1 to a communication message processing unit 13A corresponding to the display 2A. The communication transmission / reception processing unit 18 sends a communication message from the communication message processing unit 13A to the display 2A corresponding to the communication message processing unit 13A. Similarly, the communication transmission / reception processing unit 18 sends a communication message to be transmitted from the display 2B to the main unit 1 to a communication message processing unit 13B corresponding to the display 2B. The communication transmission / reception processing unit 18 sends a communication message from the communication message processing unit 13B to the display 2B corresponding to the communication message processing unit 13B.

FIG. 6 is a block diagram showing the configuration of the display 2A of the present embodiment, and the same configuration as in FIG. 27 is denoted by the same reference numeral. The display 2A includes a communication message processing unit 20, a body information processing unit 21, a body information storage unit 22, a display information processing unit 23, a display information storage unit 24, a screen control processing unit 25a, a display processing unit 26, a liquid crystal display 27, and parameter processing. The unit 28, the parameter storage unit 29, the touch sensor 30 (operation unit), the operation input processing unit 31, the inter-display coordination processing unit 32, and the information creation unit 33. The screen control processing section 25a of this embodiment performs the processing described in this embodiment in addition to the processing of the existing screen control processing section 25.

Although the structure of the display 2A is shown in FIG. 6, the structure of the display 2B is the same as that of the display 2A. Compared with the conventional technology, an inter-display coordination processing unit 32 and an information production unit 33 are added to transmit information to other displays, thereby enabling simple communication between users via the display.

<Example 5-1> In the adjustment meter of this embodiment, the operation of displaying the control amount PV, the set value SP, the operation amount MV, and the state of the display 2B on the monitoring screen of the display 2A is similar to that of Example 1-1 (Fig. 25) Example 2-1 (Figure 28) is the same. In the adjustment meter of this embodiment, the operation of transmitting the state information of the display 2A from the display 2A to the main body unit 1 is the same as that of Example 2-2 (FIG. 29). In the adjustment meter of this embodiment, the operation of displaying the parameter setting value and the state of the display 2B on the parameter setting screen of the display 2A is the same as that of Example 2-3 (FIG. 30). The operation of changing the parameter setting is the same as that of FIGS. 26 and 37.

Next, an example of an operation when the information setting screen is displayed on the display 2A in the adjustment meter of the present embodiment will be described. When the user sets the information setting screen on the display 2A, the user can operate the touch sensor 30 of the display 2A to select the information receiving target, and then switch to the information creation screen to create and send information. An example of an operation of transmitting information from the display 2A to the display 2B in the adjustment meter will be described with reference to FIG. 7.

When the operation input processing unit 31 of the display 2A detects the user's operation on the touch sensor 30 of the display 2A (YES in step S200 in FIG. 7), the operation of the user is transmitted to the screen control processing unit 25 a of the display 2A. . The screen control processing unit 25 a transmits the operation of the user to the information creation unit 33.

The information creation unit 33 of the display 2A performs information creation processing (step S201 in FIG. 7) according to the operation of the user, and after the creation is completed, it generates information for the information received by the display 2B including the content of the information created by the user. (Step S202 of FIG. 7), the generated information material is transferred to the inter-display coordination processing unit 32 of the display 2A (step S203 of FIG. 7). As described above, the information includes the identifier of the display 2A of the transmission source and the identifier of the target display 2B. The identification characters of the local and other displays 2B are stored in the display information storage unit 24 of the display 2A in advance. The details of the information creation processing will be described later.

The inter-display coordination processing unit 32 of the display 2A generates an information transmission request from the display 2A to the display 2B based on the information materials received from the screen control processing unit 25a (step S204 in FIG. 7), and transmits the generated information transmission request The communication message processing unit 20 transmitted to the display 2A (step S205 in FIG. 7).

When the communication message processing unit 20 of the display 2A receives the information transmission request from the inter-display coordination processing unit 32, it creates a communication message including the information sent from the display 2A to the display 2B (step S206 in FIG. 7), and transmits the created communication The message is sent to the main body unit 1 (step S207 in FIG. 7).

The operation of the display 2B when information is sent from the display 2B to the display 2A is the same as the operation of the display 2A described with reference to FIG. 7, and therefore description thereof is omitted.

<Example 5-2> Next, an example of an operation of displaying information sent from the display 2B on the display 2A in the adjustment meter of the present embodiment will be described with reference to FIG. 8. The display 2A displays information from the display 2B in the second display area of the monitor setting screen or the second display area of the parameter setting screen in the same manner as the status information of the display 2B.

If the communication message processing unit 20 of the display 2A receives a communication message containing the information sent from the display 2B-the display 2A from the main unit 1 (YES in step S300 of FIG. 8), it interprets the communication message and extracts the information to generate the display 2B. The information display request received by the display 2A (step S301 in FIG. 8).

When the inter-display coordination processing unit 32 of the display 2A receives the information display request from the display 2B-the display 2A received from the communication message processing unit 20, it generates the information material from the display 2B including the content of the information (step S302 in FIG. 8) , The generated information material is stored in the display information storage unit 24 (step S303 in FIG. 8).

The screen control processing section 25a of the display 2A reads out the information materials sent from the display 2B from the display information storage section 24, and generates screen display materials for displaying the information sent from the display 2B in the second display area (shown in FIG. 8). Step S304), and the generated screen display material is transferred to the display processing unit 26 of the display 2A (step S305 in FIG. 8).

The display processing unit 26 of the display 2A controls the liquid crystal display 27 in accordance with the received screen display data. Thereby, in the second display area of the monitor screen of the liquid crystal display 27 or the second display area of the parameter setting screen, the information transmitted from the display 2B to the display 2A is displayed (step S306 in FIG. 8).

The operation of the display 2B when the information sent from the display 2A is displayed on the display 2B is the same as the operation of the display 2A described with reference to FIG.

Next, the liquid crystal display 27 and the touch sensor 30 of the display 2A and the display 2B will be described. In the following example, the display 2A is described, but the configuration of the display 2B is the same as that of the display 2A. When the display 2A is viewed from the front, as in FIG. 31, there are a region where the touch sensor 30 is arranged on the surface of the liquid crystal display 27 and a frame 2012 surrounding these. FIG. 9 is a diagram showing button operations and screen transitions of the display 2A.

<Example 6-1> An example of a monitoring screen displayed on the display 2A will be described. Because it is a monitoring screen, the display of the screen switching button is shown in FIG. 10, which means that the MONI button 204 on the monitoring screen is in a state of selecting white characters on a black background, and the PARA button 205 that is used for parameter setting and the information that is set for information are displayed. The MESS button 206 is in a non-selected state with black characters on a white background. On the monitoring screen, each value of the control amount PV, the set value SP, and the operation amount MV is displayed as the status information of the main body unit 1.

Further, the status information 207 of the display 2B is displayed at the bottom of the monitoring screen. In the example of FIG. 10, “HMI-B” which means the display 2B and “monitoring” which means the monitoring screen are displayed, and thus it is known that the display 2B is displaying the monitoring screen. Therefore, the user viewing the monitoring screen of the display 2A knows that the parameter setting operation is not performed on the display 2B, and therefore, even if the parameter setting operation is performed on the display 2A, the operations will not conflict.

<Example 6-2> Next, another example of a monitoring screen displayed on the display 2A will be described. In the example of FIG. 11, as the status information 207 of the display 2B displayed on the lowermost part of the monitoring screen, “HMI-B” which means the display 2B and “Parameter setting” which means the parameter setting screen are displayed, so that the display 2B is known The parameter setting screen is displayed. Therefore, a user viewing the monitoring screen of the display 2A knows that a parameter setting operation is being performed on the display 2B, and therefore, if a parameter setting operation is performed on the display 2A, there is a possibility of an operation conflict.

The operations of the main unit 1 and the display 2A when the monitor screen is displayed on the display 2A are described with reference to FIGS. 25 and 28 except that the buttons displayed in the third display area are different. The screen control processing unit 25a of the display 2A reads the control amount PV, the set value SP, and the operation amount MV from the main body information storage unit 22, and reads the status information of the display 2B from the display information storage unit 24 to generate screen display data The data is transmitted to the display processing unit 26 of the display 2A. The screen display data is used to display the control amount PV, the set value SP, and the operation amount MV in the first display area, and the status of the display 2B in the second display area. And the MONI button 204, the PARA button 205, and the MESS button 206 are displayed in the third display area (step S1206 in FIG. 28).

<Example 6-3> Next, an example of an operation when the monitor screen of the display 2A is switched to the parameter setting screen will be described. When the user presses the PARA button 205 in a state where the monitor screen is displayed on the display 2A as shown in FIG. 10, a parameter setting screen as shown in FIG. 12 is displayed (transition of 300 in FIG. 9).

When the screen control processing unit 25a of the display 2A detects that the PARA button 205 is operated via the operation input processing unit 31 of the display 2A, it switches from the monitoring screen to the parameter setting screen. The operations of the main unit 1 and the display 2A when the parameter setting screen is displayed on the display 2A are described with reference to FIGS. 25 and 30 except for the different types of buttons displayed in the third display area.

The screen control processing section 25a of the display 2A reads the parameter setting values from the parameter storage section 29, and reads the status information of the display 2B from the display information storage section 24, generates screen display data, and transmits the data to the display processing of the display 2A. Section 26. The screen display data is used to display a name or number of a parameter for identifying a parameter and a set value of the parameter in a first display area, and display a state of the display 2B in a second display area, and The MONI button 204, PARA button 205, MESS button 206, left arrow (←) button 208, right arrow (→) button 209, and change button 210 are displayed in the third display area (step S1410 in FIG. 30).

Since it is a parameter setting screen, during the display of the screen switching buttons, the MONI button 204 and the MESS button 206 are in a non-selected state with black characters on a white background, and the PARA button 205 is in a selected state with white characters on a black background. In the parameter setting screen, a parameter value is displayed from a plurality of parameters. In the example of FIG. 12, the value of the set value SP is displayed.

Furthermore, status information 207 of the display 2B is displayed at the bottom of the parameter setting screen. In the example of FIG. 12, “HMI-B” which means the display 2B and “monitoring” which means the monitoring screen are displayed, and it is known that the display 2B is displaying the monitoring screen.

<Example 6-4> Next, an example of a parameter setting change screen displayed on the display 2A will be described. When the user presses the change button 210 in a state where the parameter setting screen is displayed on the display 2A as shown in FIG. 12, the parameter setting changing screen shown in FIG. 13 is changed (transition of 301 in FIG. 9). Here, since the set value SP is displayed in the state of FIG. 12, it is a parameter setting change screen for changing the set value SP.

The parameter setting change screen displays a numerical value of a parameter of a setting change object and a plurality of buttons called a keypad. In the keypad, there are digit buttons 211 from "0" to "9", decimal point button 212, a reverse button 213 for reversing the sign, a C button 214 for deleting all the inputs, and a button for deleting the last input. BS button 215, ENT button 216 for completing the input and returning to the parameter setting screen, and CAN button 217 for canceling the input and returning to the parameter setting screen.

As before, when the user presses the ENT button 216 or the CAN button 217 while the parameter setting change screen is displayed on the display 2A, the parameter setting screen is displayed (transition of 302 in FIG. 9). When the user presses the MONI button 204 in a state where the parameter setting screen is displayed on the display 2A, the monitor screen is displayed (transition of 303 in FIG. 9).

<Example 6-5> Next, an example of an information setting screen displayed on the display 2A will be described. When the user presses the MESS button 206 with the monitoring screen or the parameter setting screen displayed on the display 2A, the information setting screen shown in FIG. 14 is changed (transition of 304 in FIG. 9). The example in FIG. 14 shows a case where four displays 2A, 2B, 2C, and 2D are connected to the main body unit 1.

An example of the operation when the information setting screen is displayed on the display 2A will be described with reference to FIG. 15. The communication message processing unit 20 of the display 2A receives a communication message indicating the status of the display 2B from the main unit 1 (step S400 in FIG. 15), interprets the communication message, takes out the status information of the display 2B, and transmits it to the display information processing of the display 2A. Unit 23 (step S401 in FIG. 15). The display information processing unit 23 of the display 2A stores the received status information of the display 2B in the display information storage unit 24 of the display 2A (step S402 in FIG. 15).

The screen control processing unit 25 a of the display 2A generates status information for displaying the display 2B and screen display data of buttons and the like shown in FIG. 14, and transfers the data to the display processing unit 26 of the display 2A (step S403 in FIG. 15).

The display processing unit 26 of the display 2A controls the liquid crystal display 27 in accordance with the received screen display data. Thereby, the information setting screen shown in FIG. 14 is displayed on the display 2A (step S404 of FIG. 15).

Since the screen is set for information, during the display of the screen switching buttons, the MONI button 204 and the PARA button 205 are in a non-selected state with black characters on a white background, and the MESS button 206 is in a selected state with white characters on a black background. A message receiving destination selection button is displayed on the message setting screen. Among the information receiving target selection buttons, there are HMI-A button 218 of display 2A, HMI-B button 219 of display 2B, HMI-C button 220 of display 2C, and HMI-D button 221 of display 2D. .

Here, since the information setting screen is being displayed on the display 2A, it means that the HMI-A button 218 of this machine is in a non-selectable state with black characters on a gray background. The display 2C and the display 2D are neither the local device nor the receiving target, so the HMI-C button 220 and the HMI-D button 221 are in a non-selected state with black characters on a white background. The user can press any of the HMI-B button 219, HMI-C button 220, and HMI-D button 221 to select any of the display 2B, display 2C, and display 2D other than the device as the destination for receiving information. . In the example of FIG. 14, the user selects the display 2B as the destination for receiving information and presses the HMI-B button 219, so the HMI-B button 219 is in a state of selecting white characters on a black background. Furthermore, a message button 222 for setting a message is displayed on the message setting screen.

<Example 6-6> Next, an example of an information creation screen displayed on the display 2A will be described. When the user presses the information button 222 while the information setting screen is displayed on the display 2A as shown in FIG. 14, the information creation screen shown in FIG. 16 is changed (transition of 305 in FIG. 9).

A plurality of buttons called information input keys are displayed on the information creation screen. In the example of FIG. 16, the small-sized liquid crystal display 27 has a narrow display area and cannot display English or Japanese character keyboards, and the number of information input keys is limited. Specifically, among the four information type selection keys and keypad information type selection keys displayed as information input keys, there are a WHO button 223 for selecting information WHO, an IAM button 224 for selecting information IAM, and a TEL button for selecting information TEL. 225, and a QUIT button 226 for selecting the information QUIT.

In the keypad, there are numeric buttons 227 of "0" to "9", a space button 228 for entering a blank space, a hyphen button 229 for entering a hyphen (-), and a C button 230 for deleting all the input BS button 231 for deleting the last input, ENT button 232 for completing the input and returning to the information setting screen, and CAN button 233 for canceling the input and returning to the information setting screen.

As mentioned above, Information WHO is a questioning message asking a user who is monitoring or operating another display who this person is. The message IAM is a message indicating to the user who is monitoring or operating another display by including the user's own ID in the message. Therefore, the information IAM can also be used as a response to the question information WHO. The ID is an employee number or a telephone number agreed in advance among users. If the ID is known, the users can communicate with each other by telephone, email, or the like.

The message TEL is a request message requesting a user who is monitoring or operating another display to call himself by including the user's own telephone number in the message. The message QUIT is a request message requesting the user who is operating another display to suspend the operation.

In the lowest area 234 of the information creation screen, information that the user is creating is displayed. If the user presses the ENT button 232, the input is completed and a message is sent. When the user presses the CAN button 233, the input is aborted without sending a message. When the user presses the ENT button 232 or the CAN button 233, the screen returns to the information setting screen (transition of 306 in FIG. 9).

When the user presses the MONI button 204 in a state where the information setting screen is displayed on the display 2A, the monitor screen is displayed (transition of 307 in FIG. 9). When the user presses the MESS button 206 with the monitoring screen displayed on the display 2A, the information setting screen is displayed (transition of 308 in FIG. 9). When the user presses the PARA button 205 in a state where the information setting screen is displayed on the display 2A, it becomes a parameter setting screen (transition of 309 in FIG. 9).

An example of an operation when the information creation screen is displayed on the display 2A will be described with reference to FIG. 17. The screen control processing unit 25 a of the display 2A generates screen display data for displaying the buttons and the like shown in FIG. 16, and transmits the data to the display processing unit 26 of the display 2A (step S500 of FIG. 17).

When the user presses the ENT button 232 (YES in step S506 in FIG. 17), the information creation unit 33 of the display 2A generates information for display 2B including information content created by the user (step in FIG. 17). S507), the screen control processing unit 25a of the display 2A displays the information setting screen (step S508 in FIG. 17). The operation after the information material is generated is described in FIG. 7.

When the user presses the CAN button 233 (YES in step S509 of FIG. 17), the screen control processing unit 25 a of the display 2A displays the information setting screen without generating the information material (step S508 of FIG. 17). ). In addition, if the liquid crystal display 27 is large, it is naturally possible to display an English or Japanese character keyboard.

<Example 6-7> Next, an example of a screen displayed on the display 2B when information is sent from the display 2A to the display 2B will be described. The example of FIG. 18 shows an example of transmitting information from the display 2A to the display 2B when the display 2B is displaying a parameter setting screen. Status information 207 of the display 2A is displayed at the bottom of the parameter setting screen. In the example of FIG. 18, “HMI-A” which means the display 2A and “Messaging” which means the transmission of information are displayed. Therefore, a user viewing the parameter setting screen of the display 2B can recognize that the information is transmitted from the display 2A.

The operation of sending status information to the main body unit 1 when transmitting information from the display 2A is the same as in Example 2-2 (FIG. 29). The operation of displaying the parameter setting value and the state of the display 2A on the parameter setting screen of the display 2B is the same as that of Example 2-3 (FIG. 30).

Next, after the screen shown in FIG. 18 is displayed for a certain period of time, as shown in FIG. 19, the content of the information transmitted from the display 2A is displayed on the parameter setting screen. In the example shown in FIG. 19, "TEL" and a telephone number "7123456" are displayed in the second display area 235. The telephone number 7123456 is a telephone number of a user who is operating the display 2A.
