込処理方式。 In a control computer system that monitors and controls a plant, in the process of inputting contact information that indicates the operating status of plant components such as valves and pumps, the same contact changes state (from on to off, off, etc.) within a specified time. A contact input input device characterized in that it includes means for counting the number of times the cycle (from on to on) is repeated, and means for stopping updating of the computer internal state value of the contact when the count value exceeds a predetermined number of times. Processing method.
