Abstract

PURPOSE:To return a failure state to a main contrller and to confirm failure state surely, when the normal and failure state are taken place repetitively, by providing a means which detects failed control to a terminal device controlling a load with a control signal from a main controller. CONSTITUTION:Transmission signals including an address signal, a control signal and a return request signal are transmitted to a transmission line 1 in time division multiplex transmission cyclicly for a plurality of terminal devices B1- Bn from a main controller A. The transmission signals from the line 1 are received at a logical circuit 11 at each terminal device Bi to detect the coincidence of the address and the return signal is returned from a return output circuit 22 during the period of return request. Further, based on the control signal, a load control signal controlling a load L is generated on a line 30 and given to a terminal controller 28. According to the operation monitor signal generated from the operation monitor circuit 26, a monitor circuit 27 monitors the operating state and when normal and failed operation are repetitively detected, return signal is given to the device A. The device A gives interruption to confirm failures.
