If a data source becomes disconnected, what is the expected behavior upon reconnection?

When a data source becomes disconnected, the expected behavior upon reconnection is that the Historian will automatically reconnect. This capability is essential for maintaining data continuity and ensuring that the Historian system can resume normal operations without significant interruption.

The automatic reconnection feature is designed to handle transient network issues or temporary disconnections efficiently. Once the connection is restored, the Historian will begin to fetch the most recent data and continue recording without requiring physical intervention from users. This approach minimizes downtime and ensures that the integrity of the data collection process is preserved.

In contrast, other possibilities such as ignoring the data, fetching outdated data, or requiring manual intervention would not align with the functionality and design principles of modern data historian systems, which are implemented to support high availability and reliability in data acquisition and recording processes.
