In detail

Plant Historian AR - Alarm Rationalization

Increased Plant Safety and Security as a Result of Sustainable Alarm Management

The prioritisation of alarms is usually based on the effects of ignoring alarms (damage to people, the environment and machines) and the operator's remaining reaction time in an alarm situation.

A wrong alarm prioritisation can have the following negative effects:

Alarms with too low a priority can jeopardize the safety of the plant.
Too many alarms with a high priority lead to desensitisation of the operators.

With the help of an intuitive decision tree, the actual alarm priority is determined. A change of an alarm priority will automatically start the MOC process. When the MOC process is finished (confirmation of the changes according to the dual-control principle) the changes can be implemented in the process control system. Subsequently, Plant Historian AR will check the correct execution of the priority change.

Combined with Plant Historian AM (Alarm Management), Plant Historian AR (Alarm Rationalization) represents an essential part of systematic alarm management.
