The alarm database maintenance view presents alarm data in a table view to make it easy to view and edit the alarm database. As with other tables, you can show or hide columns and use other standard table controls and options that are provided in the menu. The menu is located in the top right corner of the table and is described in Table controls and options. Also, the filter icon and the notes icon appear on the workbench toolbar when the alarm database maintenance view is displayed.
An example of the alarm database maintenance view is shown in Figure 229.
The Alarm Database Maintenance view has two main sections:
-
