<p>PROBLEM TO BE SOLVED: To display information of a plant without any transmission delay by simplifying a method of monitoring plants on one CRT monitor. SOLUTION: The device is provided with a means which concentrically displays pieces of image information sent from respective CRTs by a video composition unit. To display the monitoring of the whole plant, a process for determining the sizes of respective divided pictures is provided and a plant picture of interest is selected and displayed at the time of monitoring. This invention makes it easy to connect displays of data of plural plants and the need for the examination of a transmission protocol which was necessary before is eliminated. Further, information is not send and received by transmission, but an image signal is controlled, so the effect that the data from the plant can be displayed without any transmission delay can be expected.</p> |
