Abstract: A facility inspection support apparatus having portable terminal equipment (2) for collecting on the field basis a patrol inspection result at each site of plant facilities, and a processor (1) for receiving the patrol inspection result data collected by the portable terminal equipment and performing a necessary data process. The processor (1) includes a data base (11) for storing in advance a plurality of patrol inspection routes, and discrimination information of patrol inspection items included in the inspection routes, and storing the patrol inspection result data collected by the portable terminal equipment, and facility management processor (15) for deriving the discrimination information of a patrol inspection item designated by the interactive apparatus and a past patrol inspection result data for the designated patrol inspection item, out of the data base, and transferring the discrimination information and the past patrol inspection result data to the portable terminal equipment (2).

Abstract: In a method for controlling output of alarm information in a system for monitoring a plant wherein process variables including analog type process variables at respective sensing points in the plant are sampled and each of the sampled analog type process variables is compared with a normal range limit value for determination as to whether it is within a normal range or within an abnormal range, an alarm limit level is determined in accordance with changes that have occurred in the process variable during the latest sampling interval. Output of alarm information is permitted in connection with the process variables that have a priority level whose value is higher than the value of the alarm limit level.
