<p>PURPOSE:To process data efficiently, by providing an operation processing device where data at many measuring points of a plant are grouped and measurement start and end are discriminated on a basis of group information to store data. CONSTITUTION:Many measured data in a plant 9 are stored in an input information table 10 through a process input/output controller 8. An operator console 7 is operated to classify data to every group information recording part 2 of an auxiliary storage device 1 under the control of a CPU6, and information and data are written to an index part 4 and a data part 5 successively. A plant state discriminating part 3 starts and terminates the recording on a basis of the state of the plant 9 in accordance with contents of the index part 4. Contents of the input information table 10 are updated periodically. The operator console 7 is operated as required to display required items from the auxiliary storage device 1 onto a CRT11 or a typewriter 12. Thus, many changing data of a large-scale plant are gathered and monitored efficiently.</p> |
