Alarm Archiving
Alarm archiving in WinCC OA is currently activated in the alert class (_alert_class). It cannot be activated independently by using the alert handling config (_alert_hdl).
Currently (NGA V2.0) there is no archive class assignment possible yet. Therefore, (similar to RDB manager) all alert history is saved in one archive group called “ALERT”.
Note: Active alerts are archived at the start of the NGA. In other words a synchronization between the already archived alerts and the active alerts takes
place.
The Save alerts
check box defines whether all alarms using this alarm class are archived or not. This is identical to the configuration used for Value Archive / RAIMA
and RDB manager.
