PROBLEM TO BE SOLVED: To provide a method for feeding back to a control mechanism a failure occurring in a failure detection device for detecting a failure.SOLUTION: A failure detection device has the state of an input signal held in a first holding unit (Bit1), and outputs the state of a first output signal which is output by the first holding unit from a first output terminal (an output terminal 81) to the outside. In this case, the failure detection device feeds back the state reported by the first output terminal at a timing when the first output terminal reports the state of the first output signal. The failure detection device is configured so as to supply a mechanism that controls its own device with the state of the first holding unit (Bit1) and the state (Bit0) to be fed back. |
