AlarmAnalysis

A DCS will generate thousands of alarms, and modern data mining techniques are necessary to highlight problem sources and areas for improvement.

But looking at the alarms alone is insufficient to fully analyze the operating environment. The AlarmAnalysis software also looks at operator moves, plant measurements, and controller outputs to obtain the best picture, and best analysis techniques, for your alarm system.

Analysis Techniques
Chattering/Frequent Alarms Alarms that chattered and/or occurred frequently
Redundancies/Subsets Sets of alarms that happened close in time, most of the time.
Stale Alarms Alarms that were in the active state for a significant lenght of time.
Alarm Clusters Groups of alarms that frequently occurred together.
Alarm Sequences Commonly occurring alarm sequences
Time Correlations Alarms plotted as a functio of time and operator shift.
Ignored Alarms Alarms that were not followed by an operator move.
Alarm / Operator Move Correlations Alarms that were correlated with an operator move.
Changed Alarms Alarm parameters that were changed by the operator.
Trip Point Analysis Determines if the alarm trip point is set just outside the normal operating range and if it provides adequate response time.
Controller Performance Determines if the controllers are responding fast enough to prevent alarms.
Deadband Analysis Determines the best deadband setting based on the measurement frequency response.
