PURPOSE:To ensure the monitoring of the state of a plant including high speed phenomena readily, by smapling the process values of the plant at a high speed, memorizing the values, and sequentially displaying the memorized data on a display device at a low speed. CONSTITUTION:A display-process starting part 15 is operated, and the normal display processing is started at a constant period. When the fact that the plant enters state in a high speed period is confirmed by the infromation from a process-input-information storing area 14, the normal constant-period displaying process is stopped, and high speed sampling is started. The process input is sampled at a high speed and stored in a high-speed-sampling-information storing area 33. The stored information is read out at a low speed and diaplayed on a display device 17. |
