Importing OPC UA Histories without using a control point

The OpcUaDevice component’s histories extension (OpcUaClientHistoryDeviceExt can import OPC UA histories without creating a control point.

Warning: Be aware that you can duplicate an OPC UA history import by unintentionally using both the OpcUaClientHistoryImport component and a control point with an ImportHistoryExt for the same discovered object. Refer to “Adding points containing OPC UA histories.”
  1. In the Nav tree, right-click on Histories under the OpcUaDevice and click Views > Opc Ua Client History Import Manager.


  2. In the view, click Discover and wait a few moments for the job to run.
    On completion, the discovery job displays a list of histories in the Discovered pane.

  3. Select one or more histories to be imported and click Add.
    The Add window opens.

  4. Modify properties to set up the history import as desired and click OK.
The driver imports the histories to the station’s history database at the time specified in the Execution Time property.
