PROGRAM SIMULATING DEVICE

摘要

PURPOSE:To totally and automatically confirm and simulate the working state of a sequence action control ladder program with use of a simple device by providing an action monitoring part which confirms simulatively the working state of the preceding ladder program. CONSTITUTION:Plural actuator action simulation ladder elements forming a simulation program are carried out during the simulation of a sequence action control ladder program. Under such conditions, the display showing a cylinder device is given on a CRT 67 of an action monitoring part 52 following the progress states of the actuator action simulation ladder elements. Thus it is possible to totally and automatically confirm and simulate the working of the sequence action control ladder program with a simple operation.
