We are inundated with information in all ways, shapes, and forms; from our cell phones, televisions, and computers, isolating information and presenting what information requires action has become essential. Standardized SCADA alarm systems are powerful tools that can be utilized in this process. It is imperative to provide warnings about developing situations so Operators can take timely corrective action. Alarms can be interruptive by nature and must be carefully managed to minimize the number of nuisance alarm activations. Unnecessary alarm activations can significantly drain operational staff resources in terms of staff time, after-hours call-outs, and workload in each plant's control room.
The International Society of Automation 18.2 describes systematically reviewing and documenting alarms to help diagnose and respond to abnormal situations. The standard outlines mandatory and recommended practices for a lifecycle approach to alarm management. Standardized work processes are used to design, implement, maintain, and monitor the alarm system.
