Abstract

PURPOSE:To detect the fault of a control signal transmission and reception means by reading the states of the control signal transmission and reception means and comparing its own state with the opposite side state each other in the respective control devices. CONSTITUTION:In the control device 1, a control circuit 3 is made to be started when the request of a fault diagnosis is issued. The control circuit 3 in the control device 1 which receives a response compares the supervisory information of an interface circuit 8 on the control device 1 side, an interface line 13 and an interface circuit 11 on a device to be controlled 10 side with the response from the control device 2. Based on the compared result, the fault diagnoses to the interface circuit 8, the interface line 13 and the interface circuit 11 are executed.
