Abstract

PURPOSE:To check the logical operation of a sequencer without connecting a process device to input/output parts to the sequencer, by providing a process simulation operating part in the sequencer. CONSTITUTION:A soft changeover switch 6 is inserted and connected to a signal line connecting a logical operation controlling part 2 and an input/output interface 3. The input/output interface 3 to which a process 4 is not connected is connected to one terminal (a) of the switch 6, and a process simulation operating part 5 is connected to the other terminal (b). The operation result of the operating part 5 is taken into the logical operation control part 2 through the switch 6 as an input value. A sequence state display equipment 8 is connected to the logical operation control part 2 and the operating part 5. The logical operation control part 2, the interface 3, and the operating part 5 constitute a sequencer 50.
