PROBLEM TO BE SOLVED: To provide a plant alarm monitoring control system improving a plant availability.SOLUTION: The plant alarm monitoring control system includes: an input device 20 outputting an operation signal of a user; a processing device 30; and an output device 10. The processing device 30 connected to a controller CTR through a network 40 includes: a memory M recording a detection value fed from the controller CTR, a detection value name, and a detection time; a first database DB1 updated when recording the detection value fed from the memory M; and a second database DB2 recording data recorded in the first database DB1 when an operation signal to display a detection value is fed from the input device 20. The output device 10 displays the detection value fed from the second database DB2 in association with detection time operation means 12A and 12B and an image. When the user operates the detection time operation means 12A and 12B, a detection value of a detection time selected by the user is output to the output device 10 from the second database DB2 of the processing device 30. |
