PLANT CONTROL SYSTEM, MONITORING OPERATION DEVICE, AND PLANT MONITORING PROGRAM

摘要

A plant control system includes a monitoring operation device and a centralized management device. The monitoring operation device comprises a calling unit which transmits a transmission request of a maintenance screen data of a control program to the management device, a maintenance screen generation unit which generates a maintenance screen by synthesizing the maintenance screen data and control program state values, and a display processing unit which displays the maintenance screen on a display. The centralized management device includes a storage device which stores control device data and maintenance screen data, and a maintenance screen processing unit which transmits the maintenance screen data corresponding to appliances and the control program state values indicating states of the control program to the monitoring operation device.
