Abstract
PURPOSE:To enable a micro computer sequencer to diagnose its output part by itself by providing a circuit which applies signals from all circuits of the output part of the microcomputer sequencer to the (m+1)-th terminal of its input part. CONSTITUTION:Circuit 6 is provided which applies signals from all circuits of output part 3 to the (m+1)-th terminal of input part 1. The sequencer is placed in diagnostic mode by switching to send a pulsating test signal to the n-number output circuits from central processor 2 in sequence. When output part 3 is normal, the test signal is sent to the m+1 terminal of input part 1 in sequence. If even one of circuits of output part 3 is abnormal, a signal to be returned to central processor 2 via the (m+1)-th terminal of input part 1 is absent. Central processor 2 judges by this signal whether output circuits are normal or not and put a display unit and alarm unit into operation through output circuits.
