<P>PROBLEM TO BE SOLVED: To display only the latest alarm or display history of a plurality of same alarms as necessary. <P>SOLUTION: An alarm display processing unit 211 displays a list of history of alarm data including time information (warning time, check time and restoration time) concerned with alarm time, message information expressing the contents of alarms, and added information (occurrence frequency, cumulative time, and levels). A sort processing unit 212 sorts the alarm data based on the added information, and sorts a group of alarm data having the same added information based on the message information so that the alarm data having the same message information are arranged side by side. A thinning processing unit 213 compares two adjacent alarm data based on the time information, deletes older alarm data when both the alarm data include the same message information, applies a thinning processing to the added information, and does not apply a thinning processing to the message information and the time information. <P>COPYRIGHT: (C)2012,JPO&INPIT |
