<p>PROBLEM TO BE SOLVED: To check the rationality of the data which are set in a control arithmetic part via an operator station (HCI). SOLUTION: An application program is previously loaded into a control system where an HCI 11A and an output part 4A are connected to a control arithmetic part 3 via a but 5. Thus, the rationality of the data which are set in the part 3 via the HCI 11A is checked to improve the reliability of the control system. In other words, the rationality is checked for plural data which are set via an HCI. As a result, the control system can be operated in a safe and stable state and the system reliability is improved.</p> |
