Abstract

PURPOSE:To detect the deterioration of an automated equipment, etc., and to realize the preventive maintenance by starting a timer with the occurrence of an operation output or an action command signal of an action controller and deciding the occurrence of abnormality when no action end signal is obtained after a limited time. CONSTITUTION:A CPU 1 reads an operation signal or an action command signal, if exists, and starts selectively a timer in response to said operation or command signal. When it is discriminated that an action end signal is received from a sequencer 11, the corresponding timer is reset. If no action end signal is received and its corresponding timer has a time-out state, the abnormality of the corresponding equipment is judged and an alarm display is given via a buzzer 14, etc. Otherwise the working of the relevant equipment is urgently stopped. As a result, the deterioration of the component elements of an automated equipment, etc., can be known previously and such an effective countermeasure is taken as the preventive maintenance, etc.
