View alarm hierarchies

The Alarm Tree Viewer ActiveX control shows the alarm group hierarchy of alarm providers selected by an alarm query. Items that appear in the Alarm Tree Viewer control include alarm providers, nodes, and groups.

You can enhance the usability of the Alarm Viewer control by using an Alarm Tree Viewer control. You can create a script so that when the operator selects an alarm provider in the Alarm Tree Viewer control, the Alarm Viewer control queries the new alarm provider.

You can configure how the Alarm Tree Viewer control appears and what data is shown. For more information, see Configure an Alarm Tree Viewer control.

When you finish configuring the Alarm Tree Viewer control, you can modify the data you are viewing by:

• Sorting the data by name.

• Updating the tree.

• Performing another query.
