About alarms
An alarm occurs when something goes wrong or is about to go wrong. Alarms can signal
that a device or process has ceased operating within acceptable, predefined limits, and can
indicate breakdown, wear, or process malfunctions. Alarms are also used to indicate the
approach of a dangerous condition.
Alarms are an important part of most plant control applications because an operator must
know the instant something goes wrong. It is often equally important to have a record of
the alarm and whether the alarm was acknowledged.
Compact applications (applications running on PanelView Plus Compact terminals) have
a limited number of alarm messages.
