摘要
PROBLEM TO BE SOLVED: To provide a simulator which makes possible to execute a completely debugged program on a real PLC.;SOLUTION: The simulator for PLC control programs executes a required simulation on a personal computer in a virtual mode, based upon a control program for PLC to be a object of working simulation and a simulated input generation program described by the same language as the control program for PLC in the simulated input generation procedure necessary for the working simulation. The PLC control program and the simulated input generation program are stored at each different region, the region reserved for the PLC control program can be read out independently when the program is downloaded to the real PLC. Further, the simulator has an engine that executes in parallel the user programs and the simulated input data generation program in accordance with the common processing system.;COPYRIGHT: (C)2001,JPO
