ABSTRACT:
A window displaying method suited to the monitoring and operating of the runs of a plant is provided. A display area whose display content is comparatively unimportant is selected from within each of a number of process monitoring frames, and it is registered beforehand as a window area capable of opening a window. In a window display mode, the window is opened in the registered window area, and a window frame is displayed in the window. Thus, an appropriate window display which does not hamper necessary monitoring information can be automatically realized without the operator's needing to carry out window movement, etc. Individual areas for the respective run stages of the process of the plant may well be registered as such window areas. Besides, in a case where a selected one of images picked up by a plurality of television cameras disposed in correspondence with a plurality of devices is displayed in the window, the symbol of the television camera is displayed near that of the corresponding device on a monitoring/operation frame, whereby the position of the television camera can be recognized on the display frame. The symbols of the television cameras are permitted to be designated through touch inputs, whereby desired images can be selected through the touch inputs of the symbols. Moreover, the display attribute of the symbol of the selected television camera is changed, whereby the television camera corresponding to the image presently under display can be recognized.
