About Alarm Management

Alarm Management is handled by the Historian Administration utility through the Alarms Maintenance screen on the DataStores > Alarms tab. On the Alarms Maintenance screen, you can choose a Start and End time of the alarms that you want to backup. You can also Purge Alarms that you do not need online to save space. Typically, you would backup the alarms before purging them. The Alarms Maintenance screen can also be used to restore an alarm backup to put the alarms online.

To schedule alarm backups, use the ihBackupAlarms.exe program in the same way that you use the ihArchiveBackup.exe to schedule data backups.

Note: If you have configured Historian to use the SQL Server, you must ensure that both Historian and SQL Servers have write access to Default Archive Path and Default Backup Path. (By default, Archive and Backup path is C:\Proficy Historian Data\Archives\.) Also, make sure that the SQL service user account has permission to create a new database in the SQL Server.
