2.5 Alarm Group Configuration
Alarm Groups can be used to change the state of atoms in the controller, including changes which cause
momentary contacts to be energized for a predetermined cycle, such as an on/off switch which is con-
trolled by a Discrete I/O module in the controller. Typically, these are used to trigger an audible or visual
alarm at an annunciator panel.
Alarm group operation is initiated when Process Alarms are detected. Alarm Group configuration provides
the ability to filter Process Alarms by Message Type and Class. All Process Alarms are evaluated against
the Filter configuration of the Alarm Group. If the message is filtered out, that group is ignored and the next
Alarm Group is checked. If the process alarm is not filtered out and the alarm is unacknowledged, the
Alarm Group is considered to be on. When this condition exists, the ON List (a list of tag.atoms and asso-
ciated values) is downloaded to the controller. When all alarms for a particular group are acknowledged,
the group is considered to be off, and a different list of tag.atoms and values, known as the OFF List, is
processed.
2.5.1 Accessing Alarm Group Configuration
Alarm Group configuration is accessed from the System Window by selecting Menu > Configure > Alarm
Groups. The Alarm Group Selection window (
Figure 2-6 ) is displayed.
In the top portion of this window is the Alarm Group Selection List. This list contains the name of each
Alarm Group which has been configured. At the bottom of the window are Add, Delete and Edit buttons,
as well as OK, Cancel and ? (Help) buttons.
