The Bacnet History Import Manager is the default view of the Trend Logs (history) extension under any BacnetDevice. Simply double-click Trend Logs to open this manager view (Figure 53).

You discover Trend Log objects in the BACnet device, and add them as history import components, each of which displays as one row in this manager view. For each import component added, a corresponding Niagara history is made in the station, and is populated with data from the BACnet Trend Log object.

Starting in build 3.6.41, support was added for Trend Log Multiple objects, also discoverable in the Bacnet History Import Manager. These are also added as history import components occupying one row in the view. However, each one typically results in multiple Niagara histories in the station. These history import components also have a special view. See Bacnet Trend Multiple View.

By default, the Trend Logs container also has a Retry Trigger, for automatic usage as needed. For details, refer to “About the Retry Trigger” in the Drivers Guide.

See BACnet Trend Log import notes for more details.
