Device Redundancy

The DAServer Manager provides the ability to assign redundant device for fail-over protection in the event of device failure. Two identical devices are expected to be configured in the DAServer Manager having identical item syntax, connected to the same DAServer.

Note: Items can not be added for updates through the Redundant Device Object if the items do not exist in both controllers.

If the Primary device fails, the DAServer will automatically switch over to the Secondary device. The Secondary device then becomes the active device with the failed Primary device reverting to the backup role. If the failed device recovers to good status, it will remain in the standby mode.
