Alarm groups

You can group alarms to make tracking and management easier. Alarm groups are logical representations of different areas of a factory, pieces of equipment, operator responsibility, or a manufacturing process.

For example, the following figure shows a three-tier alarm group hierarchy for a tank farm application.

Alarm groups are useful for filtering in alarm displays, alarm printers, and acknowledgment scripts.

Every tag is associated with an alarm group. By default, tags are assigned to main $System group. You can create a hierarchy of additional alarm groups under the $System group, up to a maximum of 32 levels.

You create alarm groups and associate tags with them while you are defining your tags in the Tagname Dictionary.

Alarm groups and group variables are not compatible with SmartSymbols. You can't use references to alarm groups or group variables in a SmartSymbol.
