Abstract:
PURPOSE: To correct an operating period of a communication timer of a sub control section automatically.
CONSTITUTION: A main control section 12 sends a period correction signal to sub control sections 13-16. The sub control sections 13-16 monitor a communication line 17. When a discrimination section makes discrimination of the period correction signal, a timer re-setting section sets the operating period of a communication timer 71 to be a predetermined period. The period of the received period correction signal is monitored and a timer period conversion section makes correction of the operating period of the communication timer 71 in matching with the period of the period correction signal as soon as the reception is finished. The operating period of the communication timer 71 of the sub control sections 13-16 is made coincident with an operating period of a communication timer 48 of the main control section 12.
