FIG. 4 shows an embodiment inside the dimming data memory 15. In this embodiment, the dimming control by the time schedule will be described, but different dimming control data is stored in the other embodiments. Memory table 40
-1 to 40-m are provided for each combination of target illumination loads that are referred to as patterns and are subject to dimming control. Each of the memory tables 40-1 to 40-m is further divided into sections called scenes in which different dimming gradations of the illumination loads related to the combination are set. Therefore,
A combination of certain lighting loads is specified by designating the pattern, and each dimming gradation of the lighting load specified by designating the scene for this pattern is specified. The schedule table 41 stores the numbers of patterns and scenes corresponding to the times. The current register 42 stores the dimming control data used for control at that time. The main control unit 11 reads out a pattern and a scene at each time according to the schedule table 41 and sets them in the current status register 42, reads out data corresponding to them from the memory tables 40-1 to 40-m, sets them, and sets control data. To control the dimming. The main controller 21 of the dimming control data setting terminal 20 is provided with a register equivalent to the current status register 42.

Main control unit 2 of dimming control data setting terminal 20
1 is provided with the program of the flowchart as shown in FIG. 8, and the program is executed at the storage setting of the dimming control data, while the main controller 11 of the main operation panel 10 is shown in FIG. A program of the flow chart as shown is provided, and the program is executed when the dimming control data is set. Hereinafter, the storage setting operation of the dimming control data will be described with reference to this flowchart. The operator of the dimming control data setting terminal 20 operates the keys of the key input unit 23 to input data instructing the storage setting of the dimming control data (81). This allows
The main controller 21 writes the data corresponding to the data in the dual port RAM 24. The transmission control unit 25 reads this data from the dual port RAM 24 and gives it to the transmission interface 26 together with the address of the terminal to be transmitted. At this time, the main control unit 11 of the main control panel 10 of the main operation panel 10 is waiting for the notification of the instruction to start the memory setting (91), and the mode which the main control unit 11 was executing is received by receiving this notification. Change and dimming control data terminal 20
The operation shifts to the operation of waiting for the data from (92). At this time, the transmission interface 14 of the main operation panel 10 changes the voltage of the transmission line 2 as shown in FIG. 7 under the control of the transmission controller 13 to indicate the reception of data. That is, the data of the dimming control data setting terminal 20 is output at the predetermined position P of the time slot indicated by T.
When this data is received, in order to show that, the pulse width of the synchronizing signal S is expanded and output as shown by the broken line. In the dimming control data setting terminal 20 that has detected this, the LCD display unit 22 displays that the transmission data has been received by the main operation panel 10 (81). After confirming this, the operator inputs the pattern to be stored and the number of the scene, and this is sent to the main operation panel 10. In the same manner as above, acceptance is shown by widening the pulse width of the synchronization signal S, The light control data setting terminal 20 which receives the data indicates that the data on the pattern and the scene related to the input is received by the main operation panel 10 and the LCD display unit 2
2 (82). Next, when the operator inputs the dimming gradation degree data relating to the change together with the number for changing the dimming gradation degree, this data is sent to the main operation panel 10, and the display of the input data and the main operation panel 10 are performed in the same manner as above. Is displayed (83).

In response to the above, when the main operation panel 10 receives the pattern and scene numbers, it accesses the corresponding memory table 40, reads the corresponding dimming control data, and stores it in the current register 42. By transmitting the control data based on this, the dimming state by the corresponding pattern and scene is reproduced (93). Following this, the arrival of the correction data is monitored (94), and when the illumination load number and the dimming gradation data of the correction arrive, the current register 42 is rewritten and the control data is sent to the control terminals 3 and 4. A dimming state based on the transmitted and corrected data is realized (95). The operator checks the dimming state, and the dimming state is further changed. Meanwhile, the dimming control data setting terminal 20 detects whether or not the correction of the dimming state with respect to the corrected lighting load is completed (84), and step 83 is repeated until the end of the correction is input. When the correction for the illumination load is completed, it is detected whether the end of the correction for the pattern and the scene is input (85), and step 83 is executed until the end is input.
Control continues. Next, when the correction end is input for the pattern and the scene, the storage setting request is notified and the reception is displayed (86). The main operation panel 10 that has received the storage setting request detects whether or not the correction end input has been made for the pattern and the scene at this time (96).
Set the contents in the corresponding memory table 40 (9
7) It is detected whether another pattern or scene is stored and stored depending on whether or not the end of the storage setting itself is input (98), and if another correction is made, the process returns to step 93 to continue the operation. . On the other hand, the dimming control data setting terminal 20 monitors whether the memory setting itself is input (87). If there is no such input, step 82 is performed.
The operation is returned to and the operation is continued. When the end of the memory setting itself is input, the end is notified, the reception of the main operation panel 10 is displayed (88), and the process ends. On the other hand, in the main operation panel 10, in step 92, the mode before the mode change is restored.

Thus, the dimming control data setting terminal 20 can change the dimming control data while confirming the input and the actual illumination state and confirming the acceptance response of the main operation panel 10. In the present embodiment, an example in which a pattern, a scene, and a lighting load are specified and the dimming gradation is changed is shown, but in another embodiment, the lighting load is additionally deleted for the predetermined pattern and the predetermined scene. , And set the dimming gradient. Further, the contents of the schedule table 41 can be modified. Further, the connection unit to which the control data setting terminal for transmitting control data such as dimming control data is connected, for example, the dimming control data stored and set according to the system is variously changed. Further, the outlet 9 may have the configuration shown in FIG. 6 as well as the configuration shown in FIG. That is, it is integrated with the monitoring terminal 5A, and the outlet 9 is provided below the switches 8-1, 8-2.
