Adding points containing OPC UA histories

If the OPC UA point you are adding has an OPC UA history, the point automatically includes a history extension (ImportHistoryExt).

Discovered objects with histories are visible in the Opc Ua Client Point Manager view.
  1. To open the Opc Ua Client Point Manager, expand Config > Drivers > OpcUaNetwork > OpcUaDevice and double-click the Points folder.
  2. To run a discovery job, lick Discover.
  3. To confirm that the points have histories, examine them in the Opc Ua Client Point Manager.


    Here are two ways to identify OPC UA objects that have histories:

    • A triangular history badge appears over the icon of the OPC UA object in the Discovered pane, for example:

    • The value under the Historizing column in the Discovered pane reports true.

  4. Select one or more objects with histories and click Add.
    The default history extension period for uploading history data is once in 10 minutes. To modify this period, configure the Execution Time property by changing the Interval value.
  5. To view histories on the property sheet, right-click the point and click Views > AX Property Sheet.
