PROBLEM TO BE SOLVED: To provide a plant monitoring control device capable of efficiently obtaining information regarding an abnormality at the abnormal time of a plant.SOLUTION: A plant monitoring control device includes a trend graph database 41 for storing trend graph data in which monitoring data is time-sequential, a warning history database 42 for storing a warning event, and a device operation/operation history database 43 for storing an operation/operation event. When the screen display mode of screen display input processing means 21 is an on-line mode, the monitoring data of current time is displayed. In a replay mode, the monitoring data of a period designated by the trend graph database 41 is replayed by replay management processing means 31. For this replaying, during a period before/after the occurrence of the warning event and the operation/operation event, replaying is executed by a set reproduction cycle, and high-speed replaying is executed in other periods.SELECTED DRAWING: Figure 2 |
