<p>PROBLEM TO BE SOLVED: To obtain a plant monitoring control system capable of allocating part of a tag structure for monitoring control data for a monitoring control over plant equipment to a device other than a control device.SOLUTION: An engineering device 3 defines tags for batch-processing monitoring control data used by a control device 1 exerting monitoring control over plant equipment and an HMI device 2 displaying a monitoring/control screen 22. The engineering device 3 defines a tag structure for storing the monitoring control data and allocates part of this defined tag structure to the control device 1 or the HMI device 2, and the control device 1 and the HMI device 2 include a control device tag memory 12 and an HMI tag memory 24, respectively storing the monitoring control data corresponding to the part of the tag structure allocated by the engineering device 3.</p> |
