<p>PURPOSE:To instantaneously confirm the state of a plant and to efficiently supervise the plant by permitting a data processing device and a CRT screen display processing device to immediately execute processings when there has been a prescribed change in the state of the plant. CONSTITUTION:A state change detection device 6 normally supervise whether a prescribed state change has occurred in a process or not while it inputs instrumentation data 01a from the plant 01. If it detects the state change, it immediately gives state change detection signals SC1 and SC2 as interruption signals to the data processing device 1 and the CRT screen display device 2. Thus, the device 1 immediately fetches instrumentation data 01a at that time, executes the processing, and outputs it as processing data 1a. The display processing device 2 displays data 1a in a CRT4. Consequently, processing data at the time of the plant state change is displayed in a display means without delay.</p> |
