If the connection between Historian and an IDAS data source is lost, what happens when it becomes available again?

When the connection between Historian and an IDAS data source is lost and subsequently restored, the system is designed to automatically restart the connection. This feature enables continuous data collection and minimizes downtime, ensuring that data is efficiently captured without requiring manual intervention.

The automatic reconnection capability is crucial for maintaining the reliability and effectiveness of data monitoring and analysis, as it allows the Historian to quickly resume operations after a temporary disruption. This ensures that valuable data is continuously collected and stored, enhancing the overall performance of the system.

Options that suggest manual intervention, system reboots, or permanent data loss do not reflect the operational efficiency built into the Historian, which focuses on seamless data handling and minimal disruption. Thus, the automatic reconnection process underscores the robustness of the AVEVA Historian’s ability to manage data sources efficiently.
