Abstract
PURPOSE:To reduce hard ware cable etc. by decreasing the number of inputs of controller, by means of allowing the operation and the state of failure to be put together into one signal by an equipment to be controlled, and of allowing this to be judged by the controller by a logic analysis. CONSTITUTION:It is subjected that an equipment to be controlled 2 starts or stops by means of receiving a command signal of starting/stopping of a controller 1, and operation thereof is outputted to the controller 1 as an information 6 of starting/ stopping, and the controller 1 operates a confirming action of the command signal 3 of starting/stopping sent priviously by means of receiving this signal. The equipment to be controlled 2 sends as the information of starting/stopping by means of putting together into one signal, and the controller 1 judges the equipment to be controlled 2 as a failed state, when the input signal does not coincided with the command signal of starting/stopping 3 by means of separating and restoring the input signal to the original state by a logic analysis.
