[UFO2_DEVICESTAT:#] (IF-Node2) Required Device Status 2 Tag The ExDesc must start with the case sensitive string: [UFO2_DEVICESTAT:#] The number following the colon (:) must be the Failover ID for the interface running on IF-Node2 The PointSource must match the interfaces’ PointSource. Location1 must match the ID for the interfaces. A lower value is a better status and the interface with the lower status will attempt to become the primary interface. 0 – 99 / None Updated by the interface on IFNode2 [UFO2_STATE:#] (IF-Node1) Optional State 1 Tag The ExDesc must start with the case sensitive string: [UFO2_STATE:#] The number following the colon (:) must be the Failover ID for the interface running on IFNode1 The failover state tag is recommended. The failover state tags are digital tags assigned to a digital state set with the following values. 0 = Off: The interface has been shut down. 1 = Backup No Data Source: The interface is running but cannot communicate with the data source. 2 = Backup No PI Connection: The interface is running and connected to the data source but has lost its communication to the PI Server. 3 = Backup: The interface is running and collecting data normally and is ready to take over as primary if the primary interface shuts down or experiences problems. 4 = Transition: The interface stays in this state for only a short period of time. The transition period prevents thrashing when more than one interface attempts to assume the role of primary interface. 5 = Primary: The interface is running, collecting data and sending the data to PI. 0 – 5 / None Normally updated by the interface currently in the primary role.
[UFO2_STATE:#] (IF-Node2) Optional State 2 Tag The ExDesc must start with the case sensitive string: [UFO2_STATE:#] The number following the colon (:) must be the Failover ID for the interface running on IFNode2 The failover state tag is recommended. Normally updated by the interface currently in the Primary state. Values range between 0 and 5. See description of State 1 tag.
