Abstract

An operator designates an image of equipment or a device using a pointing device and touch coordinate detector which detects touch coordinates of the designated equipment or device on a graphic screen. A specifier compares the display coordinates on the image of each equipment or device sent from a display coordinate detector to the touch coordinates on the graphic screen output from the touch coordinate detector and outputs data specifying the equipment or device touched by the operator to a camera switching section. The camera switching section switches from a plant equipment and device monitor camera to an operating board monitor camera. The image of the operating board is displayed in a window in a predetermined area on the graphic screen. A CRT display controller causes an operating window to be displayed for the specified equipment or device displayed in a window on the CRT display unit. The operator manipulates the plant equipment and devices on the operating window corresponding to the operating board displayed on the display unit. Data indicating any specific operation is sent to a controller through an output data transmitter together with data representing the equipment or device specified by the pointing device to thereby control the specified equipment or device.
