2. Description of the Related Art In general, a plant monitoring system inputs information from a plant device and outputs a constant calculation result information to the plant device, and monitors the plant device via the process controller. It consists of a monitoring device. This monitoring device causes the operator to recognize the occurrence of an alarm, which is determined based on the information collected from the plant equipment, on the screen. The operator recognizes the alarm from the screen and performs appropriate processing.

In such a plant monitoring system, if an abnormality occurs in the monitoring device itself, such as a communication abnormality or a memory leak, the plant cannot operate normally or falls into a very dangerous state.
It is more important than the alarms that the monitoring device judges based on the information collected from the plant equipment, and it is necessary to respond promptly and appropriately. Conventionally, when the above-mentioned abnormality occurs in the monitoring device itself, first, an operator is made to recognize the occurrence of the abnormality by a screen of the monitoring device or a buzzer for occurrence of the monitoring device abnormality. Then, the operator notifies the service person or the engineer of the occurrence of the abnormality. The service person or technician notified of the occurrence of the abnormality goes to the place where the abnormality has occurred,
While taking out information from the monitoring device as needed, the cause of the occurrence is investigated and repaired, the abnormality is recovered, and the plant monitoring system is restored.

[0004]

However, when an abnormality occurs in the monitoring device as described above, the service person or the technician goes to the site to collect information and investigate.
If the monitoring device is far from the place where service personnel and technicians are located, it will take time to move to the site, problem resolution will be delayed, or the information necessary for investigation has already disappeared when the site arrived There were some problems such as failure to do so.

The present invention has been made to solve such a problem, and an object of the present invention is to provide a monitoring device capable of recognizing an abnormality of the monitoring device and grasping the contents of the abnormality immediately.
