Abstract

PURPOSE:To execute a sequence control which is free from waste, by discriminating whether a control device is abnormal or a process is abnormal, and changing how to restart. CONSTITUTION:When an n-1 process has ended, an (n) process selective signal 13 is held by circuit 18, its output is sent to an apparatus operation command part 20, and an apparatus to be controlled is operated. When a control device becomes abnormal, a normal signal 19 becomes ''0'', operation of a timer T stops, and the apparatus to be cntrolled also stops its operation. When said abnormal condition has been restored, the signal 19 becomes ''1'', and the control operation is continued from a state of its stop time by a signal from a latch R1 of the circuit 18. When a process becomes abnormal, an abnormal signal is held in a latch R2 of a circuit 17, the latch R1 is reset, and the control operation is stopped. When this abnormal condition has been restored, the latch R2 is reset by a reset signal 16, and from a suitable process, for instance, in case of an (n) process, a signal 14 is selected and the operation is restarted.
