Configuring a system to process alarms involves adding an alarm extension to each point's property sheet. Alarm extensions
are contained in the alarm palette.
An alarm extension on a point issues alarms to the AlarmService, and updates the alarm record to reflect a state change when
the parent point goes back to a normal state. The extension also notifies the point that an acknowledgment has been received.
These basic steps are required to set up the alarming process:
- Add the proper alarm extension to each component.
Alarm extension types must match their parent component type. For example, an OutOfRangeAlarmExt goes with a Numeric point type and a BooleanChangeOfStateAlarmExt goes with a Boolean point type.
- Configure each point’s alarm extension properties to define when the point meets an alarm condition (is in an alarmed state).
- Setting up alarm routing by defining where an alarm record is to be sent. This includes sending the alarm to the alarm console.
- Configuring capacity and other alarm management properties.
- Manage the alarm archive using the alarm archive management tools.
