PURPOSE:To realize an easy comparison between the standard operation mode or an optional operation mode and the present operation mode, by connecting an auxiliary storage device having a memory file to the data processing part. CONSTITUTION:The auxiliary storage part 8 is provided at the data processing part 3 via the data transmission line 9. The standard operation mode or an optional operation mode of the plant processed at the plant state quantity detecting part 1 and the part 3 is stored in the storage part 8 automatically or a manual request. When a request is given from the operator request part 4, the part 3 extracts the requested mode of operation out of the memory file at the part 8 and then displays it on the display 7. In such way, an easy comparison is secured between the standard operation mode or an optional operation mode and the present operation mode. Accordingly, the deterioration of performance, a shift out of the standard operation mode and other factors can be monitored for the plant. |
