<p>PURPOSE:To dispense with complicated window operation by registering a window area where a window can be displayed about each display screen, and displaying a window screen in the window area registered about the display screen being in the course of display when window display is required. CONSTITUTION:A process information input-output section 31 delivers process information from a process input-output device 2 to a process information editing section 37. The process information is edited into screen display information in the section 37, and then received in a screen data base 33. Operational information sent from each of input terminals 7-10 is sent from an operational information input section 52 to an operational information judging section 36 through a man-machine information input-output section 32, and further to a monitoring screen editing section 34, which reads out screen data from the data base 33, and sends them to a screen output section 51 through the input- output section 32. In addition to that, a window judging section 39 is provided on the midway of the above routine to make the display of the window possible in an area which does not overlap with a part necessary for monitoring on a monitoring screen being displayed at present.</p> |
