METHOD FOR INSPECTING CONTROL OPERATION OF CONTROLLER AND DEVICE THEREFOR

PURPOSE:To lighten a load on a simulation device which simulates the operation of a controlled object. CONSTITUTION:Restriction conditions regarding control operation between >=2 equipments among the equipments constituting a plant are determined (step 210), necessary conditions of execution for placing equipments on which the restriction conditions are imposed in operation are determined (steps 220 and 230), equipment by equipment, from initially set control operation specifications of the control unit (step 200), and those necessary conditions of execution are mutually compared (step 240) to decide whether or not there is the possibility that the restriction conditions are not met (step 240). Then when the possibility that the restriction conditions are not met is decided, a control event initiating the possibility that the restriction conditions are not met is determined (step 270) among various control events at the time of the execution of the control operation specifications. Then the operation of the plant is sumulated based on control events of the determined control operation specifications.
