The transmission and reception of the control signal and the monitoring signal are carried out.

Side communication means 6c, communication line switching means 6d for connecting / disconnecting the main unit side communication line 3a and the terminal side communication line 3b, the terminal unit 6e receiving the control signal from the main unit 2, and the communication between the main unit 2 It comprises a timer 6f for measuring the stop time.

再び接続する。The communication line switching means 6d connects the master communication line 3a and the terminal communication line 3b when the apparatus is started. When the terminal unit 6e receives the operation signal from the master unit 2, the two communication lines are disconnected, and when the terminal unit 6e receives the stop signal, the two communication lines are connected again.

First, at the time of startup, since the base unit side communication line 3a and the terminal side communication line 3b are connected, if the base unit 2 transmits a load control signal, it is directly received by the terminal unit 4. Thus, the terminal 4 controls the load 5 connected to itself. Then, when the base unit 2 transmits the load monitoring signal, the terminal 4 that directly receives the load monitoring signal monitors the load 5 connected to itself, and transmits the load state signal directly to the base unit 2. In this way, control and monitoring of the load 5 by the master unit 2 are performed.

規の制御機能を行うことができる。When performing a new control function of the pseudo base unit 6, an operation signal is transmitted from the base unit 2 to the terminal unit 6e of the pseudo base unit 6. As a result, the communication line switching means 6d disconnects the master communication line 3a and the terminal communication line 3b. After that, the pseudo master unit 6 performs a new control function and controls and monitors the load 5 similar to the master unit 2. Then, when the new control function becomes unnecessary, a stop signal is transmitted from the base unit 2 to the terminal unit 6e of the pseudo base unit 6, and the communication line switching means 6d sets the base unit side communication line 3a and the terminal side communication line 3b. Connect. After that,
The master unit 2 controls and monitors the load 5 again. With such a configuration, a new control function can be performed without replacing the master unit 2.

滑に制御を行うことができる。Further, the pseudo master unit 6 checks the load control signal and the load monitoring signal cyclically transmitted and received when the master unit 2 is operating by the master unit side communication means 6b. If stopped, the stop time is measured by the timer 6f. If the stop time exceeds the predetermined time, it is determined that the master unit 2 has failed, and the communication line switching unit 6d disconnects the master unit communication line 3a and the terminal unit communication line 3b. Then, the pseudo master unit
6 performs control and monitoring of the load 5 in place of the master unit 2 or performs a new control function. With such a configuration, it is possible to prevent a state in which control cannot be performed, and to smoothly perform control even if the base unit 2 fails.

To add new functions. Further, even if the master unit fails, the pseudo master unit performs its substitute function, so that the load can be smoothly controlled.
