<p><P>PROBLEM TO BE SOLVED: To provide a supervisory control system which displays a chart (as shown in the figure) to grasp a state change rapidly from a list of messages easily and reliably when a state change such as abnormal conditions with a facility being supervised or recovery from abnormal conditions occur. <P>SOLUTION: A supervisory control apparatus has a means to illustrate only time-series messages having the contents identical to those of a selected message from a list of state change messages with a large display quantity. A free message determined to be necessary is selected by a mouse or the like, confirming the list of messages displayed on a HMI apparatus, and the chart is displayed by performing an illustrating operation. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
