ABSTRACT:
The inventive master station apparatus for a remote supervisory control system makes poke points for selecting remote stations displayed on a video display (3) by an output control circuit (24), so that, when an operator touches one of the poke points on a touch panel (4), a CPU (21) makes the pattern and the current status of a monitored/controlled device of the corresponding remote station and a poke point for a control command displayed. When the poke point for the control command is touched, the CPU (21) transmits a control command to the monitored/controlled device of the corresponding one of remote stations (11, 12, . . . , 1n) through a line interface (5). When control of the corresponding device is executed, the remote station transmits a signal indicating the operation thereof to the master station apparatus (1). On the basis of the operation indicating signal, the CPU (21) updates the content of a status memory (23), and the status indication displayed on the video display (3) through the output control circuit (24).
