ABSTRACT:
Disclosed is a process quantity display apparatus of the type wherein a plurality of process quantities of a plant detected by a detector are displayed by a pictorial display device and the displayed process quantity is renewed under the control of a process quantity display renewal unit which includes a significant difference operator which produces a significant difference when a displayed process quantity is to be renewed, and a display renewal judging unit which renews the display of the display device when the variation of the detected process quantity exceeds the significant difference. Instead of or in addition to a pictorial display device, a control device may be provided to control the process quantity of the plant in response to the output of the display renewal judging unit.
