Abstract
PURPOSE:To detect anomaly of the control system and the system to be controlled, by monitoring the output of the timer which is reset when commands are issued from the control system to the system to be controlled and when the execution completion signal is returned from the system to be controlled. CONSTITUTION:Control information 11 and status signal 12 are sent from control system 1 to system 2 to be controlled, and return information 13 and return reporting signal 14 are sent from system 2 at the execution completion time. Timer 3 is reset by the OR signal between status signal 12 and reporting signal 14 and starts counting again. Preset value M is set simultaneously with inputting of the status signal. Signal 16 is output when counter 5 in the timer overflows, and anomaly of system 1 or system 2 is decided by system monitor part 7 to output operation mode switching signals 19 and 20.
