FAILURE DISPLAY METHOD OF SUPERVISION AND CONTROL SYSTEM

PROBLEM TO BE SOLVED: To display state of failure or abnormity of a supervision and control object plant on a screen at the time of occurrence of them, and to prevent false confirmation on confirming operation of an observer. SOLUTION: An input of change-of-state of failure or an input of confirming operation by an observer is acquired (S1) with the failure displayed, present time is obtained as failure occurrence time in case of the occurrence of failure (S4), and the display is updated by the occurrence of failure (S5). When the failure is confirmed, the present time is obtained as failure confirmation time (S6), and it is checked whether or not the time is after the lapse of prescribed seconds from the failure occurrence time (S7), then an alarm is generated if the confirmation is operated within the prescribed seconds(S8), and an update display window is updated if the confirmation is operated after the prescribed seconds (S9). The system also includes that only failure confirmation object is displayed on the window and associated with the confirming operation, and that the update of the display of failure is locked in the confirmation input operation.
