Description

The present invention relates to a module system used for temperature control of multiple heating points (control targets) set on a mold in a large hot press machine, i.e., multiple-point temperature control, when the mold is heated uniformly or with an intentional distribution, for example.

Conventionally, a system similar to the module system used for multi-point temperature control as described above is described, for example, in Patent Document 1.

This multi-channel control system includes a host control device such as a personal computer that sends control conditions to multiple control objects and receives control status data, multiple slave control units, and a master control unit.

The multiple slave control units each control multiple control objects based on control conditions given to them by a higher-level control device, and send control status data for each of the multiple control objects to the higher-level control device.

On the other hand, the master control unit is connected to a higher-level control device and multiple slave control units, and transmits the control conditions from the higher-level control device to each slave control unit, and also transmits the control status data of each control object transmitted from each slave control unit to the higher-level control device.

In such a multi-channel control system, communication between the master control unit and each of the multiple slave control units is carried out based on communication identification information set for each of the multiple slave control units.

Japanese Patent Application Laid-Open No. 62-176295

In the multi-channel control system described above, when the communication identification information of each of the multiple slave control units is set using a mechanical setting means, such as a trimmer, if the number of slave control units is small, the setting can be done by a simple mechanical operation such as operating the trimmer.

However, increasing the number of slave control units will correspondingly increase the number of trimmers and the number of operations required. Increasing the number of trimmers and the number of operations required in this way can actually make machine operation more complicated, which can lead to setting errors, and also increases the space taken up by the trimmers.
Therefore, in the above-mentioned multi-channel control system, the number of slave control units can only be increased to the extent that the setting of the identification information for communication can be completed by a simple mechanical operation, and solving this problem has been a conventional problem.

The present invention was made to solve the above-mentioned problems of the conventional technology, and aims to provide a module system that can handle the control of a large number of control objects, by which pre-operation setup operations can be performed with simple mechanical operations when there are a small number of control objects, and by which pre-operation setup operations can be performed while saving space and minimizing setup errors even when there are a large number of control objects.

In order to solve the above problems, the present invention provides the following module system.
That is, a first aspect of the present invention is a module system composed of a dual-purpose module that can be set as either a master module or a slave module, and consisting of one master module and another slave module connected to the master module via a communication path, in which the dual-purpose module has a switch section having a first mechanical switch provided on a housing for setting and retaining whether it is to be used as a master or a slave, and a visually operable second mechanical switch provided on the housing for setting and retaining communication identification information that identifies the module for communication with other dual-purpose modules, a communication individual setting section for setting the communication identification information via individual communication without going through a connected communication path, and a communication setting identification information retention section for retaining the communication identification information set by the communication individual setting section.

In a second aspect of the present invention, the dual-use modules that are in communication with each other are connected to each other by an internal bus, and the second mechanical switch and the communication setting identification information storage unit are connected to the internal bus that is shared between the dual-use modules that are in communication with each other.

Furthermore, in a third aspect of the present invention, the communication path is configured as a serial communication path that is commonly used by all dual-purpose modules.

Furthermore, in a fourth aspect of the present invention, the first mechanical switch is arranged in a dual-use module and is arranged in a position where the setting cannot be changed while the module is in operation.

Furthermore, in a fifth aspect of the present invention, the dual-use module is further configured to have a light-emitting unit that flashes in synchronization with the master and the slaves subordinate to the same master.

Furthermore, the sixth aspect of the present invention is configured such that the individual communication setting unit can set the identification information only when the second mechanical switch is set to a specific setting common to both modules.

Furthermore, the seventh aspect of the present invention is configured to further include a device address determination unit having a second machine module setting value determination means for determining whether the setting of the second machine switch is a specific setting common to the dual-use module or another setting when the module is started up, and a communication individual setting unit function means for causing the communication individual setting unit to make a setting when the setting of the second machine switch is the specific setting.

The present invention has the extremely advantageous effect of being able to handle the control of a large number of control objects.

Note that the present invention is not limited to these embodiments, and may be embodied in various forms without departing from the spirit of the present invention.
<Embodiment 1>
＜Overview＞

This embodiment is a module system that includes one master module and multiple slave modules that are connected to the master module via a communication path, and is mainly characterized in that the master module and the slave module are configured as dual-purpose modules that can be set to either module, and the master is configured in hardware, while the slaves are configured and identified in both hardware and software.

When this module system is used, for example, for multi-point temperature control of a mold in a large hot press machine when the mold is heated uniformly or with an intentional distribution, it has the advantage of saving space and enabling pre-operation setting operations to be performed while minimizing setting errors.
<Configuration>

As shown in FIG. 1A, the module system of this embodiment includes a PC (personal computer) 0101, a PLC (program logic controller) 0102, and a recorder 0103 as a host control device that sends control conditions to a plurality of control objects (for example, heaters arranged at multiple heating points of a mold in a large hot press machine) H1, H2, ..., Hn and receives control state data of the plurality of control objects H1, H2, ..., Hn, a communication module 0110 for Ethernet (registered trademark) communication, and a dual-purpose module 0120 that is provided corresponding to the plurality of control objects H1, H2, ..., Hn and is capable of multi-channel control of one control object, and the PC 0101, PLC 0102, and recorder 0103 are connected to the communication module 0110 via a hub 0105.

The communication module 0110 and multiple dual-purpose modules 0120 are arranged in sequence from the left side of the figure on a DIN rail (a metal rail of a standard defined by German Industrial Standards, equivalent to the Japanese JIS standard) R installed on the inner wall of the factory, and these modules 0110, 0120 can be attached and detached to appropriate positions on the DIN rail R using known attachment and detachment methods.

As shown in FIG. 1B, the dual-use module 0120 is composed of a base 0130, a module body 0140, and a terminal block 0150, and the base 0130 is fixed in an appropriate position relative to the DIN rail R as described above.

A pair of arms 0131, 0131 extending toward the module body 0140 are provided at the bottom of the base 0130 fixed to the DIN rail R, while a pair of bearings 0142 (only one side is shown in FIG. 1B) are formed on the bottom base side of the module body 0140, which are rotatably fitted with upwardly protruding shafts 0132, 0132 formed at the ends of the pair of arms 0131, 0131 on the base 0130. In other words, the module body 0140 is connected to the base 0130 by rotating the pair of bearings 0142 counterclockwise in the figure with the pair of bearings 0142 fitted to the shafts 0132, 0132 of the pair of arms 0131, 0131 on the base 0130, and fixing the abutting base 0130 and module body 0140 to each other with a locking mechanism (not shown).

The base 0130 is also provided with a main body connection connector 0133, and when the module main body 0140 is rotated to connect to the base 0130 as described above, the main body connection connector 0133 of the base 0130 is fitted with a base connection connector (not shown) provided on the module main body 0140, thereby establishing an electrical connection between the two.

Furthermore, the module body 0140 is provided with a terminal connection connector 0144, and by fitting and connecting a body connection connector (not shown) provided on the terminal block 0150 to the terminal connection connector 0144 of the module body 0140, both the mechanical connection and the electrical connection of the terminal block 0150 to the module body 0140 are achieved.

In this case, the base 0130 of the dual-use module 0120 has a male connector 0135 on one side (the right side in the figure) and a female connector 0136 on the other side (the left side in the figure). The dual-use modules 0120, 0120 adjacent to each other are arranged side by side on the DIN rail R, and the dual-use module 0120 located on the right side in the figure is moved in the direction of the thick white arrow in Figure 1B relative to the dual-use module 0120 located on the left side in the figure fixed to the DIN rail R, and the male connector 0135 and the female connector 0136 facing each other are fitted together, thereby electrically connecting the two.

The communication module 0110 and the adjacent dual-purpose module 0120 are also electrically connected to each other in the same manner as the adjacent dual-purpose modules 0120, 0120 described above.

The power supply P for the dual-purpose modules 0120 thus arranged on the DIN rail R and connected and fixed to each other is supplied sequentially to each base 0130 of the dual-purpose modules 0120 through the communication module 0110. If Ethernet (registered trademark) communication is not used, the communication module 0110 is omitted, and the power supply P is supplied sequentially to each base 0130 of the subsequent dual-purpose modules 0120 through the dual-purpose module 0120 located closest to the higher-level control device among the dual-purpose modules 0120 connected and fixed to each other on the DIN rail R.

In the module system of this embodiment, as shown by the white arrows in Figures 1A and 1B, the dual-purpose modules 0120 that are connected to each other are connected to each other by an internal bus by connecting the male connectors 0135 and the female connectors 0136. In addition, serial communication is performed between the dual-purpose modules 0120 via a commonly used serial communication path shown by a thin line in Figure 1A, and the communication module 0110 converts such serial communication between the dual-purpose modules 0120 into Ethernet (registered trademark) communication.

In the module system of this embodiment, the dual-purpose module 0120 located at the leftmost position among the dual-purpose modules 0120 is the master module 0120M, and the dual-purpose modules 0120 arranged sequentially to the right of the master module 0120M are the slave modules 0120S.

The master module 0120M transmits control conditions from the higher-level control devices PC0101, PLC0102, and recorder 0103 to each slave module 0120S, and also transmits the control status data of each control object H1, H2, ..., Hn transmitted from each slave module 0120S to PC0101, PLC0102, and recorder 0103.

On the other hand, the slave module 0120S controls the multiple control objects H1, H2, ..., Hn based on the control conditions given to them by the higher-level control devices PC0101, PLC0102, and recorder 0103 via the master module 0120M, and sends the control status data of each of the multiple control objects H1, H2, ..., Hn to PC0101, PLC0102, and recorder 0103.

In other words, in the module system of this embodiment, the dual-purpose module 0120 can be set as either a master module 0120M or a slave module 0120S, and the base 0130 of the dual-purpose module 0120 is provided with a dip switch (first mechanical switch) 0137 that mechanically performs the process of setting it to be either a master or a slave.

As shown enlarged in the circle on the left side of FIG. 1B, the dip switch 0137 is designed to select the master by positioning it on the M mark side, and to select the slave by positioning it on the S mark side. In this case, by arranging the dip switch 0137 on the surface of the base 0130 facing the module main body 0140 (the surface hidden by the module main body 0140), problems caused by changing settings while the device is in operation are prevented.

The module body 0140 of the dual-use module 0120 is also provided with a trimmer (second mechanical switch) 0147 that mechanically performs other steps such as setting the module as master or slave.

This trimmer 0147 is provided so as to be visually operable in a switch box 0148 installed at the upper front part of the module main body 0140, and the master is selected by aligning the arrow engraved in the center of the centrally located disk 0147a with a predetermined character around it, as shown enlarged in the circle on the right side of Fig. 1B, after selecting the master with the dip switch 0137. In this embodiment, the master is selected by matching the character "1" engraved around the disk 0147a with the setting of the dip switch 0137 described above.
The switch box 0148 is provided with a port 0149 for connecting a communication cable together with a trimmer 0147, and reference numeral 0160 in FIG. 1A denotes a cable.

In addition to setting whether a module is a master or a slave, this trimmer 0147 also sets and holds communication identification information (module number = device address) for identifying each of the multiple slave modules 0120S during communication. In this embodiment, the module numbers of each of the multiple slave modules 0120S are set and held by mechanically aligning the arrow of the disk 0147a with the 14 characters "2-9, A-F" (excluding the character "1") engraved around the circumference of the disk 0147a.

In other words, in this embodiment, the trimmer 0147 sets and holds the module numbers of the slave modules 0120S, the number of which is 14, and can be assigned using the characters "2-9, A-F" around the disk 0147a.

The master module 0120M and the slave module 0120S are made up of a dual-use module 0120 that can be used in either way, i.e., they have the same structure and appearance. Therefore, to prevent simple connection errors, the master module 0120M and the slave module 0120S may be configured to have labels of different colors affixed or colored.

Furthermore, as shown in FIG. 2, the dual-use module 0220 includes a switch section 0260 consisting of a dip switch, which is a first mechanical switch, and a trimmer, which is a second mechanical switch, as well as a communication individual setting section 0270, a communication setting identification information storage section 0280, and a module number determination section (device address determination section) 0290.

The individual communication setting unit 0270 sets communication identification information (module number) for individually identifying multiple slave modules during communication via individual communication without going through the above-mentioned serial communication path, in other words, sets the communication identification information by software without performing mechanical operation of the trimmer.
Specifically, as shown in FIG. 1A, for example, a setting communication device 0170 is connected to the port 0149 of the switch box 0148 described above via a cable 0160, and setting is performed through communication.

In this embodiment, the communication identification information is set by the communication individual setting unit 0270 when the arrow on the trimmer disk is aligned with the letter "0", i.e., when the trimmer is aligned with a specific setting common to the dual-use module. However, at the initial setting stage of the dual-use module, the arrow on the trimmer disk is aligned with the surrounding letter "0", so as a result, it is possible to set the communication identification information by software without touching the trimmer.

Therefore, by aligning the arrow of each disk in each trimmer in multiple slave modules with the character "0", which is a specific setting common to dual-purpose modules, all communication identification information can be set by the individual communication setting unit 0270.

The communication setting identification information holding unit 0280 is configured to hold the communication identification information of each of the multiple slave modules that are set by the individual communication setting unit 0270 via individual communication without going through a serial communication path.

The module number determination unit 0290 has a second machine module setting value determination means for determining whether the trimmer setting is a specific setting common to dual-use modules or another setting when the module is started up, and a communication individual setting unit function means for causing the communication individual setting unit 0270 to set the trimmer setting if the trimmer setting is a specific setting common to dual-use modules.

In other words, the module number determination unit 0290 reads the setting information for whether the dual-purpose module is to be the master or slave, and determines the module number from either the trimmer's communication identification information or the communication identification information in the communication setting identification information storage unit 0280.

In this embodiment, when the module is started, if the arrow on the trimmer disk is pointing to the letter "0", the module number is determined from the communication identification information in the communication setting identification information storage unit 0280, and if the arrow on the trimmer disk is pointing to a letter other than "0", the module number is determined from the letter the arrow is pointing to. Then, during system start-up, the master-slave information and module number information are stored in a non-volatile memory, which will be described later, and communication via the internal bus is performed based on the stored module number.

As shown in Fig. 3, the dual-use module 0320 is composed of a CPU 0301, a non-volatile memory 0302 such as a flash memory or a ROM, and a main memory 0303 such as a D-RAM. The non-volatile memory 0302 stores programs such as a communication individual setting program and a communication setting identification information holding program, and in some cases stores a switch operation reception program that accepts the operation of the switch unit to set the master and the communication identification information of the slave, and further stores a module number determination program having a trimmer module setting value judgment subprogram and a communication individual setting unit function subprogram. The data includes signals and various information, and these programs and data are read into the holding area of the main memory 0303 and executed in the operation area. The interface 0304 includes a display interface 0305 and a communication interface 0306.
<Processing flow>

In the module system according to this embodiment, if the dual-purpose module adjacent to the communication module is to be used as the master module, first operate the dip switch to select master use and align the arrow on the trimmer disk with the surrounding letter "1".

In this way, when the mechanical operation for master use is performed using the switch section, in the dual-use module, as shown in FIG. 4A, a setting reception step (step S0401) is executed by the switch operation reception program, the settings made using the dip switches and trimmers are accepted, and the module is set as a master module after a judgment step (step S0402) (Yes).

On the other hand, if you want to use the dual-purpose module adjacent to this master module as a slave module with a module number "2" (communication identification information), first operate the dip switch to select slave use and align the arrow on the trimmer disk with the surrounding letter "2".

When such mechanical operations are performed, a setting reception step (step S0401) is executed by the switch operation reception program in the dual-purpose module adjacent to the master module, the settings made using the dip switches and trimmers are accepted, and after a judgment step (step S0402) (No), the module is set as a slave module.

Next, in the dual-purpose module that has been set as a slave module, a step of accepting settings by the trimmer (step S0403) is executed, and the setting by the trimmer, i.e., the letter "2" that the trimmer's arrow is pointing to, is accepted, and the dual-purpose module is set as a slave module with module number "2."

When this sort of allocation operation using the trimmer of the switch section is performed sequentially on multiple slave modules connected under the master module (connected to the right side of Figure 1A), each slave module accepts the character that the arrow of the trimmer is pointing to, and an individual module number is set for each.

In other words, for the number of slave modules (14 units) that can be assigned using the letters "2-9, A-F" around the trimmer's disk, module numbers, which are identification information for communication by hardware using the trimmer, are set.

When the module number exceeds "15" (the letters around the trimmer are "F" but for convenience we use "15") and a dual-purpose module is connected, the arrow on the trimmer's disk is aligned with the letter "0", which is a specific setting common to dual-purpose modules, and the following process is performed.

In other words, if the dual-purpose module located, for example, at the 15th position (16th if the master module is included) under the master module is to be made the slave module with the module number "16", first connect the setting communication device to a port on the switch box with a cable and set the module number "16" via individual communication without going through a serial communication path. As shown in FIG. 4B, the setting reception step (step S0411) is executed in the dual-purpose module located at the 15th position under the master module.

By executing this setting reception step (step S0411), the setting by the individual communication setting unit, i.e., the character "16" written via individual communication, is accepted, and then the information acquisition step (step S0412) by the communication setting identification information storage unit is executed, whereby the character "16" is stored, and the dual-use module located 15th under the master module is set as the slave module with module number "16."

For the 15th and subsequent slave modules under the master module, individual module numbers are set by sequentially setting the module numbers via individual communication using a setting communication device that does not use such a serial communication path.

In other words, for the 15th and subsequent slave modules under the master module, module numbers are set as software-based communication identification information using individual communication that does not go through a serial communication path. Note that the module system according to this embodiment is designed to connect a total of 25 dual-purpose modules.

In a dual-use module with the module number set as described above, when the module is started up, first the master or slave setting is read out, then the trimmer's communication identification information is read out, and if the arrow on the disk is pointing to the letter "0", the module number is determined from the communication identification information in the communication setting identification information storage unit, and if the arrow on the trimmer's disk is pointing to a letter other than "0", the module number is determined from the letter the arrow is pointing to.

Then, while the system is running, the master/slave information and module number information are stored in non-volatile memory, and communication via the internal bus is carried out based on the stored module number.

In this way, in the module system according to this embodiment, even when used for multi-point temperature control of a mold in a large hot press machine when the mold is heated uniformly or with an intentional distribution, the master is set in hardware and the slave is set and identified in both hardware and software, so that it is possible to save space and perform pre-operation setting operations while minimizing setting errors.

In addition, in the module system according to this embodiment, the second mechanical switch, the trimmer, and the communication setting identification information storage unit are both connected to an internal bus shared between the dual-purpose modules that are in communication with each other, which speeds up information processing.

Furthermore, in the module system according to this embodiment, the communication path shared by the dual-purpose modules is a serial communication path, which makes it easy to achieve synchronous communication.

Furthermore, in the module system according to this embodiment, the dip switch serving as the first mechanical switch is located in an invisible location, which makes it possible to avoid malfunctions caused by changing settings when the system is in an operational state.

Furthermore, in the module system according to this embodiment, the master module constantly monitors the multiple slave modules connected to it, i.e., it keeps track of the cooperation between the multiple slave modules and the attachment and detachment of each slave module, making it possible to replace slave modules while the system is running.

The module system according to this embodiment is configured with a communication module 0110 for Ethernet (registered trademark) communication, but if Ethernet (registered trademark) communication is not used, this communication module 0110 can be omitted and the PC0101, PLC0102, and recorder 0103 as higher-level control devices can be serially connected to the master module 0120M, as shown by the virtual lines in FIG. 1A.

In addition, in this embodiment, a case has been shown in which all of the multiple slave modules 0120S are connected to the master module 0120M, but this is not limited to this. As shown at the right end of FIG. 1A, the dual-purpose module 0120 may be placed away from the other slave modules 0120S, in which case the dual-purpose module 0120 can be used as a single control module (stand-alone module) 0120Sa. In this case, the control module 0120Sa that is not connected to the master module 0120M can also exchange control conditions and control state data with the PC 0101 as the upper control device via serial communication.

In the module system according to this embodiment, if the master module 0120M is not required, the dip switch of the dual-purpose module located at the position of the master module, i.e., the position closest to the higher-level control device, can be positioned on the S mark side, so that the multiple dual-purpose modules that follow it can each be used as a standalone control module.
＜Effects＞

According to this embodiment, when there are only a few control objects, it is of course possible to perform pre-operation setting operations with simple mechanical operations, and even when there are many control objects, it is possible to perform pre-operation setting operations while saving space and minimizing setting errors, thereby obtaining the extremely excellent effect of being able to handle the control of a large number of control objects.
<Embodiment 2>
＜Overview＞

This embodiment is based on embodiment 1, and is characterized in that the dual-purpose module further has an light-emitting unit, and the light-emitting unit of the master module and the light-emitting unit of the slave module under the same control flash in sync with each other.
In this way, by making the light emitting section of the master module and the light emitting section of the slave module flash in synchronization with each other, it is possible to easily find a module that has a communication problem.
<Configuration>

This embodiment differs from the previous embodiment in that, as partially shown in FIG. 5, a group of LEDs (light-emitting units) 0580 is provided in a switch box 0548 installed at the top front of the dual-use module 0520; the other configurations are the same as those of the previous embodiment.

In other words, in the module system according to this embodiment, when multiple slave modules 0520S are connected under a master module 0520M, the LED group 0580 of the master module 0520M and each LED group 0580 of the slave modules 0520S under the same master module 0520M blink in sync with each other upon receiving a command from a higher-level control device via the internal bus.

In this case, the LED group 0580 of the slave module 0520S having a communication problem (slave module 0520S having module number "4" in FIG. 5) will naturally blink out of sync with the LED groups 0580 of the other modules that are communicating normally, making it easy to find the module failure.
＜Effects＞

In this embodiment, the light-emitting elements of the master module and the multiple slave modules blink in sync with each other during operation, so that the difference in the blinking cycle of the light-emitting elements of a module that has a communication abnormality becomes noticeable, and as a result, the module in which the abnormality occurs can be quickly discovered.
