What happens to the connection between Historian and a data source when the data source becomes available again?

When a data source becomes available again after being temporarily disconnected, the connection between the Historian and the data source is automatically restarted by the Historian. This feature is essential for maintaining data continuity and minimizing downtime in data collection.

The automatic reconnection process is designed to ensure that any data that was not captured during the disconnection can be integrated once the connection is re-established, preserving data integrity and providing a seamless experience for users. This capability is particularly important in environments that depend on real-time data monitoring and analysis, as it allows for uninterrupted data flow without requiring manual intervention.

This automated functionality enhances the overall reliability of the AVEVA Historian by allowing it to adapt dynamically to changes in the availability of data sources, thereby ensuring that operational data is consistently collected and available for analysis.
