What indication shows that a data source is actively communicating with Historian?

The indication that a data source is actively communicating with the Historian is typically shown through Data Acquisition Monitoring. This process involves tracking and verifying that data is being received from the data source continuously and reliably.

When Data Acquisition Monitoring is functioning, it demonstrates that the Historian is successfully collecting and recording real-time data from the source. This ensures that the system is operating as expected, and any interruptions or inconsistencies in data acquisition can be detected promptly.

While options such as Data Refresh Notification, Connection Status Indicator, and System Alert Message provide valuable information about the system's health and status, they do not directly confirm that data is being actively communicated in the way that Data Acquisition Monitoring does. Data Refresh Notifications may indicate that updates are happening, but they do not confirm active data flow; Connection Status Indicators provide a state of connection but not specific data communication, and System Alert Messages typically notify users of issues rather than ongoing data interaction.
