<p>PROBLEM TO BE SOLVED: To provide a multi-window display device which not only prevents the load of polling from increasing even if the number of windows opened on a screen is increased but also sets a time deviation between real data and window display data. SOLUTION: A data processing part collects data from the connection units of a communication equipment and an input/output device at a constant period and stores it in a data table 6. A data change monitor part 9 monitors all data in the data table 6. When a change exists in previous period data and this period data, it is informed to only a window display processing part (one of 8a, 8b and 8c) on which data after the change is to be displayed. The informed window display processing part updates pertinent data in the window. Thus, the time deviation between real data and window display data can be set to a minimum and a difference does not occur.</p> |
