Embodiment 1 FIG.
FIG. 1 is a diagram illustrating a configuration example of the illumination control system 10. The illumination control system 10 includes a setting device 1 and an illumination controller 2 that is a control device. The setting device 1 and at least one lighting controller 2 are connected to a LAN 11 that is a wired or wireless communication network. At least one terminal device is connected to the lighting controller 2 via the communication line 12. In FIG. 1, three terminals 3 </ b> A, 3 </ b> B, 3 </ b> C are connected to the illumination controller 2. A plurality of terminals can be provided, and the number of terminals may be two or four or more. Terminal unit 3A, 3B, 3C is a control terminal unit which controls a lighting fixture. A sensor 4 such as an illuminance sensor or a human sensor, a wall switch 5 and the like can be connected to the illumination controller 2 via a communication line 12.

  The lighting controller 2 and the devices connected to the lighting controller 2 are connected by wiring over a pair of communication lines 12. The lighting controller 2 connected by the communication line 12 and each device connected to the lighting controller 2 can communicate with each other by, for example, ± 24V bipolar time-division multiplexed signals.

  The illumination control system 10 of FIG. 1 further includes a remote control relay 6 and a remote control transformer 7. A control signal line 31 extending from the terminals 3A, 3B, 3C is connected to one end of the remote control relay 6 on the input side. In the example of FIG. 1, one terminal device and one end on the input side of four remote control relays 6 are connected via a control signal line 31 extending from the terminal device. Instead of the terminals 3 </ b> A, 3 </ b> B, and 3 </ b> C in FIG. 1, a terminal with a built-in remote control relay 6 may be connected to the lighting control system 10.

  The input side of the remote control transformer 7 is connected to an external power supply, and relay drive power of the remote control relay 6 is supplied to the control side of the terminals 3A, 3B, 3C and the input side of the remote control relay 6. The relay driving power is supplied by, for example, AC 24V. One end on the output side of the remote control transformer 7 is connected to a common terminal of the terminals 3A, 3B, 3C. Further, the other end portion on the output side of the remote control transformer 7 is connected to the other end on the input side of the remote control relay 6.

  The setting device 1 is a part that performs setting operations such as simultaneous lighting or schedule lighting of the lighting control system 10, visualization of power consumption, management of a failure location, and the like. The setting device 1 is composed of a personal computer, for example.

  The lighting controller 2 performs bidirectional communication with the terminals 3A, 3B, 3C, the sensor 4, and the wall switch 5 via the communication line 12. The communication signal transmitted / received by the lighting controller 2 includes, for example, an address data area and a control command data area shown in FIG.

  The terminals 3A, 3B, and 3C are provided with an address setting unit configured by a dip switch or the like. By operating this address setting unit, unique addresses are assigned to the terminals 3A, 3B, and 3C. Addresses unique to the terminals 3A, 3B, and 3C using the address receivers of the terminals 3A, 3B, and 3C and the setting device 1 or the remote controller setting device instead of the operation of the address setting units of the terminals 3A, 3B, and 3C Can also be assigned.

  Different addresses are set in the terminals 3A, 3B, and 3C in order to specify individual terminals. Each of the terminals 3A, 3B, and 3C has a receiving unit that receives a communication signal transmitted from the lighting controller 2 through the communication line 12, and address data of the communication signal is assigned to each of the terminals 3A, 3B, and 3C. A comparison unit for comparing with the address is included. When the comparison unit determines that the address data of the communication signal matches the unique address assigned to the terminal device, the terminal device executes the control command for the communication signal and controls the remote control relay 6. When ON data is transmitted by the control command command of the communication signal, the terminals 3A, 3B, and 3C are connected between the common terminal of the terminals 3A, 3B, and 3C for controlling the remote control relay 6 and one end on the input side of the remote control relay 6. Connect them electrically. Due to the operation on the control side of the terminals 3A, 3B, and 3C, a relay drive voltage of, for example, 24V AC is supplied from the remote control transformer 7 to the input side of the remote control relay 6. When a relay drive voltage is input to the input side of the remote control relay 6, the remote control relay 6 connects the two terminals on the load side. By connecting an external power source and a load such as a lighting fixture in series between the terminals on the load side of the remote control relay 6, the power of the external power source supplied to the load such as the lighting fixture can be intermittent. In this way, the terminals 3A, 3B, 3C control the operation of the load such as the lighting fixture.

  The human sensor HS of the sensor 4 detects the presence / absence of a person within the detection range. When the human sensor HS detects a change in the presence / absence of a person, the human sensor HS transmits the information to the lighting controller 2. The illuminance sensor LS of the sensor 4 has a light receiving unit and measures illuminance. When the illuminance sensor LS receives an illuminance monitor signal requesting illuminance from the illumination controller 2, the illuminance sensor LS transmits the measured illuminance.

  The wall switch 5 includes buttons for operating lighting (ON), extinguishing (OFF), and dimming rate of the lighting fixture. Information such as an address assigned to the sensor 4 and the wall switch 5 is set using a setting device 1 or a remote control setting device not connected to the lighting control system 10 when energized.

  FIG. 2 is a conceptual diagram of a communication frame that is a unit of communication signals transmitted and received by the lighting controller 2. The communication frame includes, for example, an address data area and a control command area. The address data area includes a transmission destination address DA and a transmission source address SA. In the transmission destination address DA, address information of a transmission destination device can be designated. Specify device address A if there is one intended destination, specify group number B if the intended destination is a group containing multiple devices, and simultaneously if the intended destination is all devices. Broadcast D, which is a transmission, can be specified. The broadcast-transmitted communication signal is broadcast to all devices other than the transmission source connected to the communication line 12. A unique address is assigned as a broadcast destination address.

  The lighting controller 2 can individually operate each device by designating an address of the device and transmitting a control command. The lighting controller 2 can also operate the devices set as a group simultaneously by designating a group number and transmitting a group control command. By storing device address information and setting information such as a group number in the non-volatile memory of the lighting controller 2, a control command for an individual device or a control command for a group can be transmitted.

  Each of the terminals 3A, 3B, and 3C has a first memory, and each address information and setting information can be stored in the first memory. For example, the address information and setting information shown in Table 1 below can be registered in each device. In the example of Table 1, address information 1, 2, 3, 4, and 5 are registered in five terminals 3A, 3B, 3C, 3D, and 3E, respectively. In the example of Table 1, group information and a controller ID are listed as registration information. Group information is information for managing a plurality of terminals as a group. The illumination controller ID is ID (identification) information of the illumination controller 2. The lighting controller 2 can be provided with a second memory that stores address information and setting information of the terminals 3A, 3B, 3C, 3D, and 3E. The lighting controller 2 can store address information and setting information of all devices. The first memory and the second memory described above are, for example, nonvolatile memories.

  Here, it is assumed that since the terminal device 3E has failed, the terminal device 3E has been replaced with a replacement that is a replacement terminal device. The second memory of the lighting controller 2 stores address information and setting information of each device shown in Table 1. On the other hand, since the address information and the setting information of the exchange terminal 3F are not set, “0” is stored in each setting item in the first memory of the terminal 3F as shown in Table 1. ing.

  FIG. 3 is a communication sequence diagram of the lighting control system. Communication 1-9 shown in FIG. 3 is performed in this order. First, a signal periodically broadcast from the lighting controller 2 will be described. The signal periodically broadcast from the lighting controller 2 includes, for example, a controller ID and a terminal transmission request.

(Controller ID)
A controller ID is periodically transmitted from the lighting controller 2. The controller ID is ID information of the lighting controller 2. The controller ID is transmitted by communication 6, for example. For example, the controller ID is transmitted every minute. This controller ID is a communication signal transmitted from the lighting controller 2 by broadcast communication. Each device that has received the controller ID compares the received controller ID with the stored controller ID. When the controller ID received by each device is different from the stored controller ID, each device stores the received controller ID in the first memory. Furthermore, each device transmits a communication signal, which will be described later, to the illumination controller 2 with the change of the controller ID as a trigger.

(Terminal transmission request)
The lighting controller 2 periodically transmits a terminal transmission request by broadcast communication. The terminal transmission request can be transmitted, for example, every 3 seconds. The terminal transmission request is a request for transmission to each device connected to the communication line 12. In other words, it is a command that permits transmission of a signal from each device such as a terminal to the illumination controller 2. Each device that has received the terminal transmission request performs one of the following operations (1) to (3).
(1) Request setting information from the lighting controller 2.
(2) Request to transmit a command for monitoring the setting information of the lighting controller 2 in order to register the setting information of the lighting controller 2.
(3) Do nothing.

In the case of (1), the lighting controller 2 transmits the setting information stored in the second memory of the lighting controller 2 to the target device.
In the case of (2), the illumination controller 2 transmits a setting information monitor signal to the target device. The target device that has received the setting information monitor signal transmits the setting information in the first memory to the illumination controller 2. The lighting controller 2 that has received the setting information updates the setting information of the target device stored in the second memory with the received setting information.

  As described above, when the setting information stored in the second memory of the lighting controller 2 is updated, the lighting controller 2 that has received the setting information monitoring request from the target device first outputs a monitor signal of the setting information. Send. Then, setting information is transmitted from the target device that has received the monitor signal. Finally, the setting information received by the lighting controller 2 is stored. As described above, an increase in communication traffic is suppressed by a configuration in which the lighting controller 2 synchronizes in response to the trigger condition that the setting information received after transmitting two types of communication commands is stored in the second memory.

  As described above, when the lighting controller 2 periodically transmits a terminal transmission request, the setting information stored in the second memory of the lighting controller 2 and the setting information stored in the first memory by each device Are synchronized. In addition, although controller ID and the terminal transmission request were illustrated as a regular signal containing the address information transmitted regularly from a lighting controller to a terminal device, another signal may be included.

  Next, replacement of a terminal will be described with reference to FIG. Specifically, a process of replacing the failed terminal device 3E with the terminal device 3F will be described. First, the terminal device 3F is connected to the communication line 12 of the illumination controller 2 in an unset state. Thereafter, communication 1 in FIG. 3 is performed. In the communication 1, the operator sets the address information (5) of the terminal device 3E in the terminal device 3F using the setting device 1 or the remote control setting device. Thereby, the state 1 of FIG. 3 is implement | achieved. That is, the address information of the terminal device 3F becomes 5, and the setting information remains unset. The operator may set address information (5) by operating a dip switch provided in the terminal device 3F instead of the setting device 1 or the remote control setting device. However, the lighting control system 10 to which the terminal 3F is connected needs to be energized before and after setting the address information of the terminal 3F.

  Next, in communication 2, the terminal device 3F in the state 1 receives a terminal transmission request from the lighting controller 2. The terminal device 3F receives the terminal transmission request, and transmits a setting request to the lighting controller 2 using the change of its own device address information as a trigger. This transmission is communication 3. In the communication 3, the terminal device 3F returns a setting request to the lighting controller 2 triggered by a change in the address information stored in the first memory after the terminal device 3F receives the periodic signal. Here, the setting request is a communication command for requesting the lighting controller 2 to transmit setting information.

  In the communication 4, the lighting controller 2 that has received the setting request refers to the second memory and transmits setting information corresponding to the changed address information to the terminal 3 </ b> F. For example, the illumination controller 2 refers to the transmission source address (5) and reads the setting information of the terminal device 3E stored in the second memory. In this example, the group information (2) described in Table 1 is read. And the illumination controller 2 transmits the communication frame containing the transmission destination address and group information (2) of the terminal device 3F to the terminal device 3F.

  The terminal 3F that has received the group information (2) by the communication 4 rewrites its own setting information. Specifically, the group information in the first memory of the terminal 3F is rewritten from 0 to 2. As described above, the setting information of the terminal device 3E stored in the second memory of the lighting controller 2 is transmitted to the terminal device 3F which is the terminal device after replacement, so that the setting information can be set without the operator setting. Is possible.

  In communication 5, a terminal transmission request, which is a periodic signal, is transmitted to all devices. Here, since there is no device whose address information has been changed, there is no trigger for transmitting a setting request in each device. Therefore, all devices do nothing for the communication 5. Thus, the generation of unnecessary communication traffic is suppressed by configuring the communication of the lighting control system 10. Note that although the address information has been changed as a trigger, the change of the address information is an example, and this is defined as trigger condition 1 in FIG.

  The communication 6 is a controller ID periodically transmitted from the lighting controller 2. Here, the controller ID (1) is transmitted. The terminal device 3F that has received the controller ID (1) compares the received controller ID (1) with the controller ID (0) stored in the first memory of the terminal device 3F. When both are different, the terminal device 3F stores the controller ID (1) transmitted from the illumination controller 2 in the first memory of the terminal device 3F. Thereby, as shown in the state 3 of FIG. 3, the controller ID of the terminal 3 </ b> F is set to 1.

  The communication 7 is a terminal transmission request that is periodically transmitted from the lighting controller 2. Upon receiving the terminal transmission request, the terminal device 3F is triggered by the change of the controller ID, and designates the illumination controller 2 as a transmission destination address and transmits a setting request. This transmission is communication 7. In FIG. 3, this trigger is defined as trigger condition 2. The lighting controller 2 that has received the setting request through the communication 7 refers to the address information (5) of the transmission source, and reads the setting information (group information = 2) of the terminal 3E stored in the second memory.

  The communication 8 is for transmitting a communication frame including the address information (5) of the terminal 3F in the transmission destination address and the group information (2) in the control command from the lighting controller 2 to the terminal 3F. Receiving this, the terminal device 3F overwrites the group information (2) in the first memory of the terminal device 3F. The communication 9 is a controller ID periodically transmitted from the lighting controller 2.

  Thus, after connecting the terminal device 3F which has not been set to the lighting controller 2, the worker simply changes the address information of the terminal device 3F to the address information (5) of the terminal device 3E before the replacement, and the lighting controller 2 The setting information of the terminal 3E stored in the terminal 3F can be set in the terminal 3F. Thereby, the address information and setting information stored in the second memory of the lighting controller 2 and the address information and setting information stored in the first memory of the terminal device 3F can be synchronized. Therefore, the load of the setting work of the terminal device 3F by the worker is reduced.

  Although Embodiment 1 demonstrated the case where one terminal unit of the lighting controller 2 was replaced | exchanged, the illumination control system 10 can respond also to the case where two or more terminal units are replaced | exchanged. When exchanging two or more terminal units, the operator only needs to match the address information of the terminal units that are exchanged items and are not set one by one with the address information of the terminal unit before replacement. When the lighting control system 10 operates as described above, when two or more terminals are exchanged, it is not necessary for an operator to connect and set new terminals that are exchanged one by one. For this reason, an operator's setting work is reduced.

  In FIG. 3, the terminal 3 </ b> F requests the setting information from the illumination controller 2 in the communication 7 due to the occurrence of the trigger condition 2 accompanying the change of the controller ID. However, the terminal device 3F may refer to the fact that the group information of itself is not set but (2) is set, and cancel the setting request for the communication 7 on this condition. Thus, the structure which requests | requires only the setting information which is not set to the lighting controller 2 can suppress generation | occurrence | production of unnecessary communication traffic in the lighting control system 10. FIG.

  Furthermore, a trigger condition 2 is generated with the change of the controller ID, and the terminal device 3F is synchronized with the setting information stored in the second memory of the lighting controller 2 to cause the terminal device for a cause other than replacement of the terminal device. Even if the data stored in the first memory is corrupted, the setting information of the terminal can be synchronized with the setting information stored in the second memory of the lighting controller 2.

  In the following embodiments, the above configuration and operation can be assumed unless otherwise specified.

Embodiment 2. FIG.
The illumination control system according to Embodiment 2 can transmit information set in the exchanged terminal device 3F to the illumination controller 2. FIG. 4 is a diagram illustrating the operation of the illumination control system according to the second embodiment. In FIG. 4, the same or equivalent components as those in the first embodiment are denoted by the same reference numerals.

  In the communication 1, the group information of the terminal device 3F is changed from 2 to 3 from the setting device 1 or the remote control setting device. That is, the change of the group information accompanying the change from the state 1 to the state 2 can be performed by the operator.

  In communication 2, a terminal transmission request is transmitted from the lighting controller 2. At this time, the exchanged terminal device 3F is triggered by the change of the setting information even though the setting command of the lighting controller 2 has not been received. That is, it requests information collection. This request is communication 3. In FIG. 4, this trigger is defined as trigger condition 3. As described above, when the setting information of the terminal device is changed by the setting device 1 or the like regardless of the request of the lighting controller 2, the terminal device of the second embodiment receives the periodic signal and then sends the terminal device to the lighting controller 2. Requests monitoring of terminal setting information.

  In the communication 4, the lighting controller 2 that has received the monitor request transmits a group number monitor to the terminal device 3 </ b> F as an information collection command for the terminal device 3 </ b> F. In the communication 5, the terminal device 3F that has received the group number monitor transmits the group information stored in the first memory of the terminal device 3F to the lighting controller 2. Specifically, group information (3) is transmitted.

  Through the communication 5, the lighting controller 2 obtains the group information (3) that is the changed setting information from the terminal 3F. And by the operation | movement 6, the illumination controller 2 stores the setting information after the change received from the terminal device 3F in the 2nd memory. Specifically, the group information of the terminal 3F in the second memory is rewritten from 2 to 3.

  Thus, the setting information stored in the second memory of the lighting controller 2 is updated to the latest setting stored in the first memory of each device by transmitting the setting information changed in the terminal to the lighting controller 2. Can be synchronized with information. Furthermore, the lighting controller 2 transmits a setting information monitor command such as a group number monitor to the terminal device, and rewrites the information stored in the lighting controller 2 only after receiving the setting information transmitted from the terminal device as a response. With this communication sequence, erroneous data can be prevented from being stored in the lighting controller 2.

Embodiment 3 FIG.
In the lighting control system of the third embodiment, the setting information of the terminal device 3E before replacement is transmitted to an unset terminal device. FIG. 5 is a diagram illustrating an operation of the lighting control system according to the third embodiment. In FIG. 5, the same or equivalent components as those in the first and second embodiments are denoted by the same reference numerals.

  The exchange terminal 3F is connected to the communication line 12 of the lighting controller 2 by connection 1 which is the first process shown in FIG. At this stage, neither address information nor setting information is set in the terminal device 3F.

  The communication 2 is a controller ID that is periodically transmitted from the lighting controller 2. Here, the controller ID (1) is transmitted. The terminal device 3F that has received the controller ID (1) compares the received controller ID (1) with the controller ID (0) stored in the first memory of the terminal device 3F. Since the received controller ID (1) is different from the stored controller ID (0), the terminal device 3F stores the received controller ID (1) in the first memory of the terminal device 3F. Thereby, as shown in the state 2, the controller ID of the terminal 3F is updated from 0 to 1. All terminals may perform this comparison. In that case, a difference is found only in the terminal 3F.

  The communication 3 is a terminal transmission request periodically transmitted from the lighting controller 2. Upon receiving the communication 3, the terminal device 3F transmits a setting request to the illumination controller 2 with the change of the controller ID as a trigger. This transmission is communication 4. In the communication 4, the terminal 3F, which is an unset terminal, issues a setting request including address information (0). Address information (0) is not registered in the second memory of the lighting controller 2. Therefore, the communication 4 is a setting request including address information different from the address information stored in the second memory.

  The lighting controller 2 that has received this setting request cannot specify the setting information of the terminal 3E stored in the second memory even when referring to the transmission source address (0). In such a situation, the lighting control system of the present embodiment uses the address information of the terminal device stored in the second memory as the transmission destination address in order in order to specify the setting information of the terminal device 3E. A communication command requesting is sent. And the lighting controller 2 specifies that the terminal device which did not reply is the terminal device 3E before replacement | exchange. That is, the lighting controller transmits a signal including the address information stored in the second memory to the plurality of terminals, and sends the address information and setting information of the terminal that has not returned to the terminal 3F that is an unset terminal. Send.

  The operation algorithm performed by the lighting controller 2 in order to specify the setting information of the unset terminal is shown using the flowchart of FIG. It is assumed that the setting information of the plurality of terminals 3A, 3B,... Stored in the illumination controller 2 is arranged in the order of TU1, TU2,. In the first step S1, n = 1 is input and the transmission destination address is designated to the terminal 3A. In step S2, the group number monitor of the terminal device 3A is transmitted to the terminal device 3A.

  Next, in step S3, for example, after waiting for a processing time during which the terminal 3A will transmit a reply, the presence or absence of a reply is checked. When the reply is received, the process proceeds to step S5, n is incremented, the transmission destination address is designated to the terminal unit 3B, and the group number monitor of the terminal unit 3B is transmitted to the terminal unit 3B in step S2.

  If this process is repeated, it is found in step S3 that there is no reply from the terminal device 3E. Then, the lighting controller 2 specifies in step S4 that the terminal device 3E is the terminal device before replacement.

  In the communication 6 of FIG. 5, the lighting controller 2 transmits address information (5) regarding the terminal device 3E before replacement specified by the above-described method to the terminal device 3F. Upon receiving this, the terminal device 3F changes the address information in the first memory of the terminal device 3F from 0 to 5.

  Furthermore, the illumination controller 2 transmits the setting information regarding the terminal device 3E before replacement to the terminal device 3F through the communication 7. Specifically, a communication frame including 5 as a transmission destination address and including group information (2) as a control command is issued. Upon receiving communications 6 and 7, the terminal device 3F rewrites the address information from 0 to 5, and rewrites the group information from 0 to 2. State 3 is thus realized.

  As described above, when the lighting controller 2 according to the third embodiment receives a setting request including address information different from the address information stored in the second memory from an unset terminal, the lighting controller 2 sets the unset terminal. Specify the address information and setting information. The flowchart of FIG. 6 is a specific example of the specifying method. The process of FIG. 6 transmits a signal including address information stored in the second memory one by one to a plurality of terminals, and identifies a terminal that does not send a reply. Instead of such sequential signal transmission, a terminal that does not send a reply to all terminals may be specified. In the lighting control system according to the third embodiment, the address information and the setting information can be set in the unset terminal without the operator setting the device address and the setting information in the unset terminal.

  The operator can check the setting status of the terminal 3 </ b> F that is an unset terminal by accessing the setting device 1. If there is no unset address information and setting information in the terminal 3F, it can be determined that the setting is completed. As a precaution, it is desirable to check the communication log to confirm that no serious communication error has occurred.

Embodiment 4 FIG.
In the present embodiment, an example of group registration processing and group control operations of the illumination control system 10 will be described using the communication sequence diagram of FIG. In FIG. 7, the same or equivalent components as those in the first to third embodiments are denoted by the same reference numerals.

  First, the worker transmits a group information command (G1 = TU1, TU2, TU3) from the remote controller setter to the lighting controller 2 via the LAN 11 in communication 1. The lighting controller 2 stores the received group information in the second memory.

  In communication 2-4, the lighting controller 2 transmits a group number registration command to the terminal device 3A, the terminal device 3B, and the terminal device 3C via the communication line 12. The terminal device 3A, the terminal device 3B, and the terminal device 3B have setting information including address information and group information. Address information and setting information are stored in the first memory of each terminal.

  In communication 5, the lighting controller 2 transmits a wall switch information registration command (G 1) to the wall switch 5 via the communication line 12. Thereby, the button number corresponding to the group 1 (G1) is linked in the wall switch 5.

  Next, group control of the illumination control system will be described. First, when the user presses a button corresponding to group 1 (G1) of the wall switch 5, the state of the switch corresponding to group 1 of the wall switch 5 changes from “no press” to “with press”. The lighting controller 2 transmits an activation monitor signal, which is a confirmation command for the switch operation of the wall switch 5, to the wall switch 5 periodically, for example, every 0.5 seconds. This transmission is communication 6 in FIG.

  When the wall switch 5 receives the activation monitor signal from the lighting controller 2, the wall switch 5 confirms whether or not the state of the switch of the wall switch 5 has changed. When there is a change in the switch state, the wall switch 5 transmits an activation monitor response that is a notification of pressing the G1 button of the wall switch 5 to the lighting controller 2. This transmission is communication 7.

  The activation monitor response indicates the operation of the switch “the group 1 (G1) of the lighting controller 2 assigned with the ID LC1 is pressed”. Receiving this, the lighting controller 2 updates the status table indicating the control state of each terminal device to be controlled to (G1ON) in order to update the switch state of the status table stored in the lighting controller 2. The status table to be controlled is stored in a non-volatile memory such as a flash memory so that an unstable operation does not occur even if a power failure occurs in the lighting control system.

  Next, the lighting controller 2 transmits a group control command (G1ON) as the communication 8. A group control command (G1ON) is broadcasted from the lighting controller 2 to the terminals 3A, 3B, and 3C via the communication line 12, and the lighting fixtures connected to the terminals 3A, 3B, and 3C are turned on. The internal operation of the terminals 3A, 3B, 3C at this time will be described below.

  The terminals 3A, 3B, and 3C that have received the group control command (G1ON) compare the group number (G19) of the transmission destination address with the group number registered in its own device. When the group number of the transmission destination address matches the group number registered in the own device, the target device processes the group control command.

  In the case of the configuration shown in FIG. 1, the terminals 3A, 3B, and 3C in which the group 1 (G1) is registered are controlled as a load by turning on the load side in the case of a terminal having a built-in remote control relay 6. Turn on the connected luminaire.

  The illumination controller 2 transmits a wall switch display command command (G1ON) to the wall switch 5 as the communication 9. (G1ON) is group-broadcasted from the lighting controller 2 to the wall switch 5 via the communication line 12, and the wall switch 5 turns on the LED of G2 that is the corresponding button in red.

  When a button corresponding to group 1 (G1) of the wall switch 5 is pressed by the user, the wall 10 is transmitted at the timing of receiving the activation monitor (SW1) that is transmitted periodically, for example, every 0.5 seconds. A notification of pressing the G1 button of the wall switch 5 is transmitted from the switch 5 to the illumination controller 2 as an activation monitor response. This transmission is communication 11.

  The lighting controller 2 that has received the activation monitor response transmits a group control command (G1OFF) as the communication 12. A group control command (G1OFF) is broadcast to the terminals 3A, 3B, and 3C via the communication line 12 from the lighting controller 2, and the lighting fixtures connected to the terminals 3A, 3B, and 3C are turned off.

  The lighting controller 2 also transmits a wall switch display command command (G1OFF) as the communication 13. (G1OFF) is group-broadcasted from the lighting controller 2 to the wall switch 5 via the communication line 12, and the wall switch 5 lights the LED of G2 which is the corresponding button in green.

  In this way, the lighting controller 2 can turn on or turn off the terminals 3A, 3B, and 3C that have been set as a group.
