PURPOSE:To improve monitoring ability and safety of a plant by storing plant data signals which are processed in an input processing part, in a plant data base and deciding a direction of the change of plant process values in a condition change deciding part. CONSTITUTION:The plant data signals inputted through a process input device 1 are processed in the input processing part 3, and the signals coming from the input process part 3 are inputted to the plant data base 5 and stored as the plant data. The direction of the change of the plant process values is decided by the condition change deciding part 7 from the plant data which are stored in this plant data base 5. Then, the decided result in the condition change deciding part 7 and the plant data stored in the plant data base 5 are indicated on a display device 12. With this arrangement, even the delicate change of the process can be easily detected. |
