Next, the operation of the first embodiment of the present invention constructed as above will be described. First, the main controller 1
The process of operating the operation panel 5 to set the mode will be described with reference to the flowchart of FIG. When any switch of the mode designating section 31a is operated, the operated switch is determined.

When the switch is the pattern setting switch 41, the timer is started. Then, the state of the pattern setting switch 41 is judged, and the timer is counted while the switch 41 is on. Then, when the set time is counted by the timer, the pattern setting mode is set and the time counting operation of the timer is stopped.

On the other hand, when the group setting switch 43 of the mode designating section 31a is operated, the timer is started. Then, the state of the group setting switch 43 is determined, and the timer is counted while the switch 43 is on. Then, when the set time is counted by the timer, the group setting mode is set and the time counting operation of the timer is stopped.

When 7 is operated, the mode switching process to the monitoring mode is immediately performed.

A pattern setting mode as in the first embodiment.
The mode and group setting mode is the pattern setting switch 41.
Since the mode switching is performed only after the group setting switch 43 and the group setting switch 43 are turned on for a set time, the pattern setting switch 41 and the group setting switch 43 are erroneously operated to change the mode. It is possible to prevent switching.

Next, a second embodiment of the present invention will be described with reference to FIG.
The flow chart will be described. Since the configuration of the second embodiment is the same as that of FIGS. 1 to 5, detailed description thereof will be omitted. First, the reception data received by the transmission / reception unit 21 of the main controller 15 is sent to the control unit 23,
It is determined whether the received data is the voltage mode signal of the parent activation. Then, the received data is judged, and if there is no error in the received data, the received data is stored in the received data storage unit 25 via the main control unit 24.

On the other hand, if there is an error in the received data, error processing is performed and then the processing ends.

On the other hand, the reception data received by the transmission / reception unit 21 of the main operating unit 15 is sent to the control unit 23, and when it is determined that the reception data is not the voltage mode signal of the parent activation. Determines whether or not the switch SW1 for designating whether or not to determine the ACK response signal of the base unit 11 for the current mode signal transmitted from the monitoring terminal device 14 is closed, and the switch SW1 must be closed. If so, the process ends.

On the other hand, when it is determined that the switch SW1 is closed, the transmission / reception unit 21 transmits the ACK response signal of the terminal device to the current mode signal transmitted from the monitoring terminal device 14. If the ACK response signal is received and there is no error in the ACK response signal, the ACK response signal is stored in the reception data storage unit 25. If the ACK response signal has an error, the processing is terminated without storing the ACK response signal in the reception data storage unit 25.

When the display request switch of the operation switches S is operated, it is stored in the reception data storage unit 25 and the light emitting element L corresponding to the illumination load is stored based on a part or all of the reception data. Is lit. For example, the light emitting element L is turned on by the illumination data for 64 circuits out of the illumination data for the illumination load of 256 circuits.

Therefore, if only 64 circuits are provided as the light emitting elements, the illumination load of 256 circuits can be allocated and monitored, and it is not necessary to upsize the device.

Further, by providing a switch SW1 for designating whether or not to judge the ACK response signal of the base unit 11 with respect to the current mode signal transmitted from the monitoring terminal 14, the switch SW1 is provided depending on the system condition. The function of detecting only the transmission data from the master unit and the function of detecting the transmission data from the master unit and the transmission data from the terminal unit can be switched by the same hardware.
