/UFO_Interval=n
Units for n: milliseconds
Default:
1000

The Failover Update Interval specifies the rate at which UniInt updates the Failover Heartbeat tags as well as how often UniInt check on the status of the other copy of the interface.
The /UFO_Interval is only used if the Failover Control Input PI tags are collected on an unsolicited basis. If the Input PI tags are scanned, the Failover Update Interval is determined by the scan class the tags are associated with.
The value of n specifies the Update Interval in milliseconds and must be the same on both interface computers.

Host PI server for Exceptions and PI tag updates

The value of the /host startup parameter depends on the PI server configuration. If the PI server is not part of a collective, the value of /host must be identical on both interface computers.
If the redundant interfaces are being configured to send data to a PI Server collective, the value of the /host parameters should equal different members of the collective.
This configuration will ensure output continue to be sent to the Data Source if one of the PI servers becomes unavailable for any reason.
