Alarm setup

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:

1. 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.

2. Configure each point’s alarm extension properties to define when the point meets an alarm condition (is in an alarmed state).

3. Setting up alarm routing by defining where an alarm record is to be sent. This includes sending the alarm to the alarm console.

4. Configuring capacity and other alarm management properties.

5. Manage the alarm archive using the alarm archive management tools.
