PURPOSE:To reduce the internal load of a computer and to reduce the capacity of a display memory by skipping the display processing as long as the process data has no change and then editing the process data if it has a change. CONSTITUTION:A display processing function 5a skips the display processing if the process data has no change. Meanwhile a display editing processing function 3a checks whether the process data has a change or not and edits only the changed process data. Then the function 3a sets an updating flag when the change of the process data is confirmed. Therefore the display processing is skipped as long as the process data has no change. Thus it is possible to obtain a process monitor controller that can reduce the internal load of a computer and also can reduce the capacity of a display memory. |
