<p>PURPOSE: To eliminate the waste that the same process is repeated at each time and shorten the time from requesting to display completion by editing data of only a changed part of a screen by a central processor, and displaying the edited changed part data over a fixed part. CONSTITUTION: This system has the central processor 12 which gathers and processes plant data 18 from a remote place and the display device 11 which displays the plant data, and the display device 11 has its display screen divided previously into the fixed part which does not relate changes of the plant data and the changeable part which depends upon changes of the plant data. Then the display device 11 is stored with the fixed part in advance, the fixed part of the screen requested to be displayed is displayed by the display device 11 itself, and only the changed part is edited and outputted by the central processor 12. Consequently, the waste that the same screen fixed part information is outputted from the central processor 12 at each time is eliminated and the time from requesting to screen display completion can be shortened.</p> |
