<p>PURPOSE: To keep high relaibaility of a plant monitor/controller by providing separately a means which performs the processing concerning the control that requires high reliability and a means which performs the processing concerning the monitoring that requires lower reliability than the former processing when the monitoring and controlling of a plant is carried out by a touch operation. CONSTITUTION: A CRT 1 displays and monitors the plant state value such as the plant process value, etc. A touch controller 3 detects the touch coordinates via a touch device 2 placed on the CRT 1 and also retrieves the screen information and the operation information through a data base 8 and based on the display screen number and the touch coordinates. A CRT processor 4 shows a prescribed screen on the CRT 1 corresponding to the screen information, and a controller 6 controls a plant based on the control information.</p> |
