JP, 2016-181454, A

  As described above, in the communication in the lighting control system, a signal standard dedicated to lighting control such as DMX signal and a signal standard capable of lighting control and setting processing such as RDM signal exist. Under the former standard, in order to enable manual setting of various settings such as the address of the lighting device, it is necessary to provide a switch or the like in the power supply circuit device of the lighting device. When it is necessary to change the setting after installing the lighting device, it is necessary to open the cover of the case of the power supply circuit device and switch the switch. The power supply circuit of the lighting device is usually installed at a high place, and it is often laborious to operate the switch of the power supply circuit every time the setting is changed. On the other hand, under the RDM standard or the like, since remote processing of setting change becomes possible, it can be said that the above switch is unnecessary.

  By the way, when constructing a lighting control system, a lighting device compatible with the RDM standard and a controller compatible with the RDM standard are not necessarily introduced at the same time. In other words, there are cases where the controller does not support the RDM standard (that is, it supports only the DMX 512) even though the lighting apparatus side supports the RDM standard. In such a case, various settings on the lighting device side need to be manually set by a switch or the like also provided in the power supply circuit device of the lighting device, and the configuration for manual setting may be left on the lighting device side. desirable. However, when the lighting device side has a configuration for manual setting such as a switch while complying with the RDM standard, if the remote setting by the RDM signal and the manual setting by the switch etc. are not properly adjusted, confusion in the setting will occur for the user. There is a possibility that

  Therefore, it is an object of the present invention to provide a slave circuit capable of suitably performing various settings relating to illumination control, even when connected to either a controller dedicated to illumination control or a controller capable of performing illumination control and setting processing. Do. Another object of the present invention is to provide a lighting power supply device and a lighting control system using such a slave circuit.

  The slave circuit to the controller in the lighting control system according to the present invention includes a switch unit capable of manually selecting a switch priority mode or a remote priority mode and manually specifying setting values for the lighting control system, and a lighting control signal from the controller or setting processing In the case where the communication section capable of receiving the signal based on the setting value, the illumination control section that causes the illumination power circuit to execute the illumination control based on the illumination control signal, and the setting processing signal includes a new setting value, the switch priority A setting processing unit is provided that does not process a new set value when the mode is selected, and changes the current set value to a new set value when the remote priority mode is selected.

  According to the slave circuit having the above configuration, the switch processing unit enables manual selection of the switch priority mode or the remote priority mode and manual specification of the set value, and the setting processing unit is configured to include the new set value. When the switch priority mode is selected, the new set value is not processed, and when the remote priority mode is selected, the current set value is changed to the new set value. As a result, a slave circuit capable of suitably performing various settings relating to lighting control is realized even when connected to either a controller dedicated to lighting control or a controller capable of lighting control and setting processing.

  Furthermore, the slave circuit stores the contents of selection and designation by the switch unit, and the switch priority mode when the setting processing signal includes the switch enable command and the switch priority mode is selected by the switch unit. Is stored in the memory, and when the setting processing signal includes the switch activation command and the remote priority mode is selected by the switch unit, the remote priority mode is maintained and stored in the memory, setting processing When the signal includes the switch invalidation command, the remote enable / disable unit determines the remote priority mode and stores it in the memory regardless of the selection by the switch unit, and the setting processing signal includes a new setting value In the case where the switch priority mode is stored, the setting processing unit does not process the new setting value and If the previous mode is stored is configured to change the current settings to the new settings. Thus, the switch priority mode or the remote priority mode can be switched by the setting processing signal from the controller, and the selection of the remote setting processing and the manual setting processing can be performed in a simple and appropriate manner.

  In particular, the present invention is suitably applicable when the illumination control signal is a signal conforming to the DMX 512 standard and the setting processing signal is a signal conforming to the RDM standard.

  The setting value may indicate an illumination control signal and an address for receiving the setting processing signal. This facilitates handling of the address change accompanying the change of the connection configuration of the plurality of slave circuits to the controller.

  Further, the setting value may indicate designation of illumination control performed when reception of the illumination control signal is stopped. This makes it possible to flexibly specify the illumination control when the illumination control signal is not received at the time of a power failure of the controller or the like before or after the installation of the slave circuit.

  Further, a plurality of output channels to which the lighting power supply circuit is connected may be provided, and the setting value may indicate designation of the output channel to be used among the plurality of output channels. Thus, the response to the change in the connection configuration of the lighting power supply circuit with respect to the slave circuit is facilitated.

  Further, the setting processing unit may be configured to reset a part or all of the current setting values to the setting value designated by the switch unit in response to a predetermined command included in the setting processing signal. As a result, when the use of the slave circuit is finished, the actual set value is made to coincide with the set value indicated by the switch section, and smooth handling at the time of reuse of the slave circuit becomes possible.

  Furthermore, a response generation unit for transmitting a response signal to the setting processing signal from the communication unit to the controller is further provided, and when the setting processing signal includes a predetermined command, the response generation unit includes the current own machine address and the switch unit. May be configured to generate a response signal associated with a part or all of the setting values designated by. Thus, each setting value can be confirmed from the controller side even after changing the setting of the slave circuit or after changing the connection configuration of the plurality of slave circuits with respect to the controller. In particular, when the set value is an address, the connection position of each slave circuit can be traced, and the manageability is improved.

  Further, a lighting power supply device according to the present invention includes any one of the slave circuits described above and the lighting power supply circuit. Furthermore, the lighting control system of the present invention includes the lighting power supply device and a controller capable of outputting a lighting control signal and a setting processing signal. As a result, a lighting power supply device and a lighting control system that achieve the above respective effects are realized.

FIG. 2 is a block diagram of a slave circuit and a lighting control system including the same according to an embodiment of the present invention. 5 is a flowchart illustrating the operation of a slave circuit according to an embodiment of the present invention.

Embodiment
FIG. 1 shows a block diagram of a lighting control system 1 according to an embodiment of the present invention. The lighting control system 1 includes a control device 2, a controller 3, and lighting devices 4-1 to 4-n. The lighting devices 4-1 to 4-n will be collectively referred to as the lighting device 4 generically or on behalf of any one. Each lighting device 4 includes the LED power supply 5 and the lighting fixture 8 and has the same configuration in the block diagram. Each LED power supply device 5 includes a slave circuit 6 (slave substrate) and an LED power supply circuit 7 in, for example, one housing. The control device 2 and the controller 3 are connected by a LAN communication line, the controller 3 and the lighting devices 4 are connected by an appropriate communication line, and the lighting devices 4-1 to 4-n are daisy chained. Alternatively, the controller 3 and each lighting fixture 4 may be wirelessly connected. The lighting fixture 8 is an LED lighting fixture having an LED array in this embodiment.

  The control device 2 is, for example, an ITACS manufactured by Iwasaki Electric Co., Ltd., and includes a processing unit 21, a storage unit 22, a user I / F 23, and an input / output unit 24. The processing unit 21 is configured by a processor or the like that integrally controls the entire control device 2, and the storage unit 22 stores programs and data. The user I / F 23 is, for example, a graphical user interface (GUI) on a touch panel. The input / output unit 24 is a LAN port or the like, and is connected to the controller 3 (input / output unit 31) via a LAN cable. The control device 2 outputs a control command to the controller 3 based on the information stored in the storage unit 22 or the information input from the user I / F 23.

  The controller 3 is a lighting controller corresponding to the DMX 512 standard (hereinafter referred to as “DMX controller”) or a lighting controller corresponding to the RDM (Remote Device Management) standard (hereinafter referred to as “RDM controller”). The controller 3 includes an input / output unit 31, a CPU 32, a memory 35, and a communication unit 36. The controller 3 functions as a master device for each lighting device 4, and transmits a control signal to each lighting device 4 based on a control command input from the control device 2.

  When the controller 3 is a DMX controller, the CPU 32 includes a signal generation unit 33. When the controller 3 is an RDM controller, the CPU 32 includes a signal generation unit 33 and a response processing unit 34. These units are connected in such a manner that they can exchange signals and data with one another via a bus. The CPU 32 and the memory 35 can be included in one microcomputer. The CPU 32 can execute not only the functions of the units included therein but also general control functions such as communication control of the communication unit 36, overall control of the signal generation unit 33 and the response processing unit 34, etc. Do. The memory 35 is a storage unit such as a RAM, a ROM, or the like that stores programs, files, and data. The communication unit 36 functions as a master communication unit for the slave circuit 6 (communication unit 61) of each lighting device 4. Hereinafter, the configuration of each part will be described as the controller 3 is an RDM controller unless otherwise noted.

  The signal generation unit 33 generates a control signal based on the control command from the control device 2, and transmits the control signal from the communication unit 36 to the lighting device 4. This control signal is a signal conforming to the DMX 512 standard for illumination control (hereinafter referred to as "DMX signal") or a signal conforming to the RDM standard for setting processing (hereinafter referred to as "RDM signal" or "command") . That is, the signal generation unit 33 generates a DMX signal when performing lighting control such as lighting, extinguishing, dimming of each lighting device 4, and generates an RDM signal when performing setting processing of each lighting device 4. Do.

  The DMX signal is a one-way signal, whereas the RDM signal is a two-way signal. Therefore, in the communication of the RDM signal, a command is transmitted from the controller 3 to the lighting device 4, and a response to the command is sent back from the lighting device 4 to the controller 3 (the lighting device 4 spontaneously transmits a response signal to the controller 3). Can not send). In the setting process, the setting or changing (SET) of the setting value of the lighting device 4 to be processed, the acquisition (GET) of the setting value of the lighting device 4 to be processing, or a search in the entire lighting devices 4-1 to 4-n (DISCOVERY) is included. The set values will be described later. The DMX frame constituting the DMX signal and the RDM frame constituting the RDM signal are identified by the difference in the value of the predetermined field. Specifically, the value of the start code of the ASC (Alternative Start Code) field common to both frames differs between the DMX frame and the RDM frame, and this is appropriately identified in the slave circuit 6.

  The response processing unit 34 processes the response received from each lighting device 4 via the communication unit 36. The response processing unit 34 converts the format of the response to the command generated by the signal generation unit 33 or analyzes it as necessary, and outputs the response to the control device 2. Thereby, the control device 2 can output information related to the setting of the lighting device 4 to the user I / F 23 based on the response.

  The slave circuit 6 is a circuit board (slave board) including the switch unit 60, the communication unit 61, the CPU 62, and the output channel 68. The CPU 62 includes a lighting control unit 63, a switch validation / deactivation unit 64, a setting processing unit 65, a response generation unit 66, and a memory 67. These units are connected in such a manner that they can exchange signals and data with one another via a bus. The CPU 62 can be one microcomputer. The CPU 62 performs the communication control of the communication unit 61, the illumination control unit 63, the switch enable / disable unit 64, the setting processing unit 65, the overall control of the response generation unit 66, the memory 67, etc. It is assumed that a general CPU function not specified is also executable. The memory 67 is a storage unit such as a RAM, a ROM, etc., which stores programs, files and data, and includes a non-volatile memory. The memory 67 may be external to the CPU 62. In this case, the CPU 62 and the memory 67 may be included in one microcomputer.

  The communication unit 61 functions as a slave communication unit for the communication unit 36 as a master communication unit. The communication units 61 of the lighting devices 4-1 to 4- (n-1) are daisy-chained, and when they receive the DMX signal or RDM signal, they capture the DATA field corresponding to the start address of the own device and receive the received DMX signal. Or transmit the RDM signal to the subsequent lighting device 4.

  The output channel 68 includes a plurality of channels (for example, 4 channels), one LED power supply circuit 7 may be connected to each channel, and one LED power supply circuit 7 may be connected to multiple channels. . For example, the four color LEDs of red (R), green (G), blue (B) and white (W) may be controlled to be lit corresponding to the four channels. In this embodiment, an example in which only one channel is used (that is, an example in which one LED power circuit 7 is connected to one slave circuit 6) is shown, but the number of channels used is not limited thereto. . Further, the number of channels provided in one slave circuit 6 is not particularly limited. An address is set to each of the output channels 68. That is, for example, if four output channels 68 can be used in a given lighting device 4, that lighting device 4 will use four addresses from its start address.

  The switch unit 60 is configured by a dip switch, a rotary switch, and the like. For example, with dip switches, setting values of about 1 bit (binary) to 3 bits (eight values) can be efficiently set for each of predetermined setting values. In addition, larger numbers can be efficiently set by the plurality of rotary switches. Each value selected or designated by the switch unit 60 is stored in the memory 67. Hereinafter, various setting values will be described.

(1) Selection of switch priority mode / remote priority mode The dip switch selects the switch priority mode or the remote priority mode. The switch priority mode is a mode in which the setting value designated by the dip switch is prioritized over the setting value designated by the RDM signal (hereinafter also referred to as “SW priority mode”). The remote priority mode is a mode in which the setting value designated by the RDM signal is prioritized over the setting value designated by the dip switch (hereinafter also referred to as “RDM priority mode”). For example, "0" is assigned to the RDM priority mode and "1" is assigned to the SW priority mode by the 1-bit dip switch. The process at the time of receiving the DMX signal is the same regardless of whether the SW priority mode or the RDM priority mode is selected.

(2) Designation of Start Address The start address of the slave circuit 6 is set by the rotary switch. For example, by providing three rotary switches for setting numerical values in the hundreds, tens and ones places, respectively, it is possible to respectively specify numerical values corresponding to one universe (512 addresses).

(3) Specification of lighting control when DMX signal is not received While lighting apparatus 4 is supplied with power, lighting control of lighting apparatus 4 is performed when controller 3 (and control apparatus 2) fails or communication failure occurs. Situations may occur where DMX signals are not received despite possible states. As described above, it is necessary to determine in advance the lighting control to be performed by the lighting device 4 in a state in which the DMX signal is interrupted or stopped (discontinued state). As illumination control when no such DMX signal is received, for example, all light on / off, maintenance of the final state (reproduction of the state immediately before the interruption of the illumination control signal) or 2-state dip switch (ie 4-value) Other controls (conditional control, lighting at a predetermined dimming rate, etc.) may be specified.

(4) Designation of Output Channel 68 The dip switch designates which of the output channels 68 is to be used. For example, when channels CH1 to CH4 are provided as output channel 68, use of CH1, use of CH1 and CH2, use of CH1 to CH3, or use of all CH1 to CH4 is made by a 2-bit dip switch (ie 4-value). The use may be specified.

  When the DMX signal is received, the illumination control unit 63 causes the LED power supply circuit 7 connected to the output channel 68 to execute illumination control specified by the DMX signal. The LED power supply circuit 7 controls the lighting state of the lighting fixture 8 according to the lighting control. For example, in illumination control, dimming of 256 gradations can be represented by 8-bit data of the DATA field of the DMX signal.

  When the RDM signal includes a switch enable command or a switch disable command, switch enable / disable unit 64 determines and determines the SW priority mode or RDM priority mode in relation to the mode selection by switch unit 60. The stored mode is stored in the memory 67.

Specifically, the switch enable / disable unit 64
· When the RDM signal includes a "switch activation command" and "SW priority mode" 1 "is selected by switch unit 60," SW priority mode "is determined and stored (ie, switch Maintain selection by section 60)
· If the RDM signal includes a "switch activation command" and "RDM priority mode" 0 "is selected by switch unit 60," RDM priority mode "is determined and stored (ie, switch Maintain selection by section 60)
· When the RDM signal includes the "switch invalidation command" and the "SW priority mode" 1 "is selected by the switch unit 60, the" RDM priority mode "is determined and stored (ie, the switch Change from selection by part 60)
When the RDM signal includes the “switch invalidation command” and the “RDM priority mode“ 0 ”” is selected by the switch unit 60, the “RDM priority mode” is determined and stored (ie, the switch Maintain the selection by section 60).
In other words, when the RDM signal includes the “switch invalidation command”, the “RDM priority mode” is “regardless of the selection of the switch unit 60 (that is, both“ 1 ”and“ 0 ”). Determined and stored.

  If the RDM signal (command) includes a new setting value, and the RDM priority mode is stored, the setting processing unit 65 changes the current setting value to a new setting value. On the other hand, even when the RDM signal includes a new setting value, setting processing unit 65 ignores the new setting value included in the RDM signal and stores the current setting if the SW priority mode is stored. Maintain the value. The new setting values may include values indicating (2) setting of the start address, (3) designation of illumination control when no DMX signal is received, and (4) designation of an output channel to be used.

  Further, the RDM signal may include a reset command for returning each setting value to the setting value designated by the switch unit 60. Specifically, when the reset command is received, the setting processing unit 65 reads the setting value (hereinafter referred to as "manual setting value") designated by the switch unit 60, and sets the current setting value to this manual setting value. Change to The reset command may be for all manual setting values or may be for some manual setting values.

  The response generation unit 66 generates a response to the received command, and transmits the response from the communication unit 61 to the controller 3. The response may include an acknowledgment for the command, a current setting value, and the like. As described above, the response processing unit 34 of the controller 3 processes this response. Also, a switch confirmation command may be provided to request acquisition of part or all of the manual setting values, in which case the requested manual setting values are included in the response.

  The LED power supply circuit 7 converts the voltage supplied from the input power supply (not shown) into a current suitable for lighting the lighting device 8 (a current waveform, a current whose current value is controlled, etc.), and the lighting device 8 Supply to When the input power supply is an AC power supply and the lighting fixture 8 is an LED lighting fixture, the LED power supply circuit 7 generates a DC constant current from a rectifier circuit that full-wave rectifies the AC power supply and an output voltage of the rectifier circuit. It has a DC / DC converter that outputs it to the lighting fixture 8. Thereby, the LED power supply circuit 7 supplies power to the lighting fixture 8 according to the signal input from the slave circuit 6 (output channel 68), and controls lighting of the lighting fixture 8.

  FIG. 2 shows a flowchart regarding processing of illumination control and setting processing in the slave circuit 6. It is assumed that each manual setting value by the switch unit 60 is stored in the memory 67 before the start of the flowchart. Then, in step S100, the communication unit 61 receives the control signal from the controller 3.

  In step S110, the illumination control unit 63 determines whether the control signal is a DMX signal. If the control signal is a DMX signal (Yes at step S110), the illumination control unit 63 causes the LED power supply circuit 7 to perform illumination control specified by the DMX signal at step S112. Thereafter, the process returns to step S100. On the other hand, when the control signal is not the DMX signal, that is, when the control signal is the RDM signal (No in step S110), the process proceeds to step S120.

In step S120, the switch enabling / disabling unit 64 determines whether the RDM signal includes a switch enabling command. If the RDM signal includes a switch activation command (step S120, Yes), the process proceeds to step S124.
In step S124, switch validation / deactivation unit 64 determines whether or not the SW priority mode is selected by switch unit 60. When the SW priority mode is selected (Yes in step S124), the switch validation / invalidation unit 64 maintains the SW priority mode in step S126. On the other hand, when the SW priority mode is not selected, that is, when the RDM priority mode is selected (No in step S124), the switch enable / disable unit 64 maintains the RDM priority mode in step S128.

On the other hand, when the RDM signal does not include the switch activation command in step S120 (step S120, No), the process proceeds to step S122.
In step S122, the switch enable / disable unit 64 determines whether the RDM signal includes a switch disable command. If the RDM signal includes a switch invalidation command (step S120, Yes), the process proceeds to step S128. On the other hand, when the RDM signal does not include the switch invalidation command (No in step S120), the process proceeds to step S130.
In step S128, the switch enabling / disabling unit 64 determines the RDM priority mode regardless of whether the SW priority mode is selected or the RDM priority mode is selected by the switch unit 60, and stores it in the memory 67. Remember. After step S126 or S128, the process proceeds to step S130.

  In step S130, the setting processing unit 65 determines whether the RDM signal includes a new setting value. If the RDM signal includes a new setting value (Yes at step S130), the process proceeds to step S132. On the other hand, when the RDM signal does not include a new setting value (No at step S130), at step S140, setting processing unit 65 (and response generation unit 66) performs other processing, ie, setting value acquisition or various searches or Execute appropriate processing such as reset. Thereafter, the process returns to step S100.

  In step S132, the setting processing unit 65 determines whether the RDM priority mode is stored. When the RDM priority mode is stored (Yes in step S132), in step S134, the setting processing unit 65 updates the current setting value to a new setting value. When the RDM priority mode is not stored, that is, when the SW priority mode is stored (No in step S132), the setting processing unit 65 maintains the current setting value in step S136. After step S134 or S136, the process returns to step S100.

  As described above, in the slave circuit 6 according to the present embodiment, the switch unit 60 capable of manually selecting the SW priority mode or the RDM priority mode and manually specifying the setting value for the lighting control system 1; In the case where the communication unit 61 capable of receiving the RDM signal based on the set value, the illumination control unit 63 that causes the LED power circuit 7 to execute illumination control based on the DMX signal, and the RDM signal includes a new set value When the priority mode is selected, a new setting value is not processed, and when the RDM priority mode is selected, the setting processing unit 65 changes the current setting value to a new setting value.

  As described above, when the switch unit 60 enables manual selection of the SW priority mode or the RDM priority mode and manual specification of the setting value, and the RDM signal includes a new setting value, the setting processing unit 65 performs the SW priority mode. When is selected, the new set value is not processed, and when the RDM priority mode is selected, the current set value is changed to the new set value. Therefore, the slave circuit 6 capable of suitably performing various settings relating to lighting control is realized even when connected to either the DMX controller dedicated to lighting control or the RDM controller capable of performing lighting control and setting processing.

  Furthermore, the slave circuit 6 stores the contents of selection and designation by the switch unit 60, and when the RDM signal includes the switch enable command, and the SW priority mode is selected by the switch unit 60. The SW priority mode is maintained and stored in the memory 67, and the RDM priority mode is maintained when the RDM signal includes the switch enable command and the RDM priority mode is selected by the switch unit 60. And the switch enable / disable unit 64 determines the RDM priority mode regardless of the selection by the switch unit 60 and stores it in the memory 67 regardless of the selection by the switch unit 60, and the RDM signal is new If the setting processing unit 65 stores the SW priority mode, the setting processing unit 65 And Do not process the set value, if the RDM priority mode is stored is configured to change the current settings to the new settings.

  Thus, in this manner, the SW priority mode or the RDM priority mode can be switched by the setting processing signal from the controller 3, and the selection of the remote setting processing and the manual setting processing can be performed in a simple and appropriate manner. .

  The above configuration is particularly useful, for example, in the following cases. For example, it is assumed that the LED power supply device 5 (or the lighting device 4) is shipped or installed in a state where the SW priority mode is selected by the switch unit 60. If the switch invalidation is not performed, the application of the SW priority mode is maintained, and the setting value can not be changed by the RDM signal (the casing of the LED power supply 5 at the high place as described above) It is necessary to open the lid and operate the switch section 60). However, by using the switch invalidation command as described above, the application of the RDM priority mode becomes possible, and the setting value can be changed by the RDM signal.

  Also, for example, it is assumed that the controller 3 is initially configured by the DMX controller (that is, the manual setting by the switch unit 60 is performed under the SW priority mode) and the DMX controller is replaced by the RDM controller thereafter. In this case, the controller 3 (RDM controller) sends a switch overriding command to each slave circuit 6 after replacement, which makes it possible to change the setting using the RDM signal thereafter, and the RDM signal function can be used without problems. Become.

  Conversely, it is assumed that the controller 3 is replaced by the RDM controller with the DMX controller. In this case, by processing the switch activation command as described above, application of the SW priority mode becomes possible, and manual setting of setting values using the switch unit 60 becomes possible again.

  Here, the setting value may indicate an address for receiving the DMX signal and the RDM signal. Thereby, the response to the address change accompanying the change of the connection configuration of the plurality of slave circuits 6 to the controller 3 is facilitated.

  Further, the setting value may indicate designation of illumination control to be performed when reception of the DMX signal is stopped. As a result, it becomes possible to flexibly specify the illumination control when the illumination control signal is not received at the time of a power failure or the like of the controller 3 before or after the installation of the slave circuit 6.

  Further, a plurality of output channels 68 to which the LED power supply circuit 7 is connected may be provided, and the setting value may indicate the designation of the output channel 68 to be used among the plurality of output channels 68. Thus, the response to the change in the connection configuration of the LED power supply circuit 7 to the slave circuit 6 is facilitated.

  In addition, the setting processing unit 65 may be configured to reset a part or all of the current setting values to the manual setting values in accordance with a reset command included in the RDM signal. As a result, when the use of the slave circuit 6 is finished, the actual set value is made to coincide with the set value indicated by the switch section 60, and the smooth handling at the time of reuse of the slave circuit 6 becomes possible. For example, the subsequent use with a DMX controller or a smooth transition to stand-alone use after recovering the LED power supply 5 is possible.

  Furthermore, a response generation unit 66 is further provided to transmit a response signal (response) to the RDM signal (command) from the communication unit 61 to the controller 3, and when the RDM signal includes a switch confirmation command, the response generation unit 66 The present invention may be configured to generate a response signal in which the current own-machine address is associated with part or all of the manual setting values. Thus, each setting value can be confirmed from the controller 3 side even after the setting change of the slave circuit 6 or the connection configuration of the plurality of slave circuits 6 with respect to the controller 3. In particular, when the set value is an address, it is possible to track the connection position of each slave circuit 6 and the like, and its manageability is improved.
