Alarm Database Maintenance view
This view presents alarm data in a table to make it easy to monitor and edit the alarm database.
The alarm database resides in a station file system under the station’s alarm folder.
The upper portion of the window contains the alarm history table. As with other tables, you can show or hide columns and use other standard table controls and options that are provided in the Table Options menu. The Table Options menu is located in the top right corner of the table and the export toolbar icon is available on the toolbar.
The lower portion of the screen provides controls for managing the history database.
