PURPOSE:To attain proper display by using three information, i.e. the read state of a monitored object, the stored change generating information of the monitored object and the current displayed state of the monitored object, to determine the contents displayed as the state of the monitored object. CONSTITUTION:In case of displaying a monitored result on a display device 2, the contents to be displayed as the monitored result are determined by using three information, i.e. the read state of the monitored object, information stored in a monitor change detecting and storing memory 10 and the current displayed state of the monitored object without simply displaying the read monitored information as it is like an ordinary method. Consequently, monitored object reading work per unit time can be reduced and the accurate state of the monitored object can be displayed. |
