Abstract

An object of the present invention is to quickly and accurately detect disorder or abnormality of a process state which occurs in a plant and to appropriately perform an operation for normalizing disorder or abnormality of the process without depending on experience or skill of an operator.

A control system of the plant is divided into groups having relation, such as, the plant, processes, or steps, and a monitor picture is created for each of them. When an alarm is raised, the alarm is displayed on a picture associated with the alarm. A guidance picture for supporting how to deal with the alarm is provided.
