An alarm analysis system for providing statistics on alarms collected by a process control system including an alarm server receiving and storing alarms from one or more processes supervised by the control system. The alarm analysis system is run on the alarm server and the alarm analysis system is adapted to automatically produce and display the statistics in real time based on the alarms stored in the alarm server.

Alarm analysis system and a method for providing statistics on alarms from a process control system

A method and an alarm processing system for deciding what alarm, out of a number of alarms generated in an industrial plant or process, to present to a system operator. The method includes creating hiding rules, associating each hiding rule with a real-world object, storing these rules in a storage means, receiving an alarm related to a real-world object, determining if a hiding rule is associated with the real-world object evaluating the hiding rule, deciding from the hiding rule whether to present or hide the alarm, selectively and actively hide such alarms that are decided to be hidden and not presenting the alarm to the system operator. The invention also includes an alarm processing system and a computer program for carrying out the method.
