<p>PROBLEM TO BE SOLVED: To provide a controller capable of forcefully stopping all control programs all together when desired I/O processing is not performed, without requiring special means for simulation.SOLUTION: A controller uses a scenario program 80 for determining whether I/O processing performs a desired operation during the execution of simulation by a control program 20. If the scenario program 80 determines that the I/O processing during the execution of simulation by a control program 20 does not perform a desired operation, a linked simulation control unit 11 stops the execution of the control program 20 by an own controller and another controller.</p> |
