Abstract

A supervisory control system including a control unit to which an object load is connected and an operation unit, both being connected to each other via a communication line. The object loads can be controlled according to desired various patterning control by sending out a control request signal to the communication line by the operation of the operation unit, a supervisory unit and an operation display unit, which have been developed for use in the supervisory control system. The operation unit, the supervisory unit and the operation display unit are so constructed as to constitute multi stage connection, thus in an application of these units in the manner of multi stage connection, they are easily available for a large scale supervisory control system with many object loads. Further an operation display unit which functions in a reaction display mode, an operation unit, and a supervisory unit with a temporal inhibit function for interlocking movement between the control operation of the operation unit and supervisory action of the supervisory unit, have been developed for users'"'"' convenience.
