Therefore, there is also a problem that the operation monitoring operation becomes complicated.

On the contrary, in the latter case, in order to identify the alarm state of each process amount, the alarm state is displayed in characters near the process amount in which the alarm is generated, or the process amount in which the alarm is generated. However, the number of display items on one screen becomes enormous in a complicated plant, and the operation monitoring operation becomes complicated.

The present invention has been made in view of such a conventional problem, and divides an enormous number of variable data into several groups related to each other, and only a variable data of a desired group is designated by a supervisor. Is combined with the fixed data display, or variable data of a desired group is filtered so that it can be displayed in a bright color that can be clearly distinguished from the remaining variable data. It is an object of the present invention to provide a plant monitoring device capable of achieving the above.

Further, the present invention provides a plant monitoring apparatus in which a display color of a group of related variable data is displayed in a color different from a normal color or a display mode when an alarm occurs, so that a monitoring person can easily grasp the alarm state. The purpose is to do.
