<p>PURPOSE:To speedily execute operation manipulation to the control state of a plant by simultaneously observing a schematic flow diagram to need supervisory, a block diagram, a trend graph and a logic diagram on one CRT display device and further, freely changing the size of a display picture as needed. CONSTITUTION:Since the schematic flow diagram to be needed for the operation manipulating of the plant, block diagram and logic diagram, etc., are separately housed to divided frame memories A-D, the picture is freely switched by the instruction of a keyboard 8 and the diagrams can be simultaneously displayed on one CRT display 1. Thus, when a system is designed, in a plant supervisory and operation manipulating device, a table to determine an importance degree, which can be forecasted in advance, is provided. Then, arithmetic is automatically executed according to the plant state at that time or the selection of the keyboard 8 and the picture of the high importance degree can be preferentially displayed.</p> |
