<p>PURPOSE:To decrease the setting frequency of a condition setting list by patterning the display conditions with combination of plural pieces of control information to turn this pattern into a number and securing the coincidence between the pattern number and the TAG number showing a place which is displayed based on the display conditions. CONSTITUTION:A fixed screen is displayed on a CRT 10 and a TAG No 9 is added to the fixed screen to show a specific position on the screen where a mobile screen is displayed. Then a condition setting list is produced for setting the relation with the control information on the input signals received from an actually controlled device, the bits of a process variable, the word data, etc. The contents of the condition setting list includes the TAG No 9, the process variable name, the input signal name, and various conditions for display, etc. In this case, plural input signal names, process variables can be set and a situation can be set in accordance with the situation set under the actual process control with use of a combination pattern of those signal names and variables. At the same time, the combined pattern is enumerated and the end of the TAG No 9 is set equal to this pattern number. As a result, the number of settings is decreased.</p> |
