Seamless, split-second switchovers, only triggers when the data source changes.

Switchover can trigger on changes in point value or quality, for a single point or any point in a group.

Allows selection of a preferred data source.

No dependency on timers reduces switchover latencies.

Rate of change monitor to switch when data flow slows down.

Complete access to both data sources at all times to facilitate diagnostics.
