PROBLEM TO BE SOLVED: To reduce the number of human misses and to uniform the quality of debugging verification, by transmitting and connecting a process machine simulator for PLC debugging to a PLC to be debugged and virtually expressing plant facilities to be controlled by the PLC in a general personal computer, because human misses may be easily generated in the the verification of the PLC to be debugged by preparing a temporary plant facility program in the target PLC and returning the answer of plant facilities or manually returning the answer of the plant facilities by using an external switch device. SOLUTION: The process machine simulator device for PLC debugging is provided with a general-purpose personal computer, a display part, a hydraulic calculation part, a sequencer engine for machine logic answers, a data management part, and a communication process part.
