Verifying an OPC UA Connection with GraphWorX

When you establish a new OPC UA connection, you can verify its functionality with GraphWorX. You can add the selected OPC UA tag to a GraphWorX display and view its value in runtime.

To verify an OPC UA connection with GraphWorX:

  1. Open GraphWorX in the configuration mode (default).
  2. On the Home ribbon in the Shapes section, click A to add a descriptive label.

  3. Write the desired text inside the label box.

  4. Add a Process Point element from Dynamics > Process Point and go to the right panel, tab Dynamics > DataSource:

    OPC UA Process Point - Data Source

  5. Select the dots to open the Data Browser, expand the path Data Connectivity > OPC UA > My OPC UA Connection > SYSTEM and select the tag MyTag Click OK to confirm.

  6. GraphWorX will fill automatically the property DataSource:

  7. Use the options on the upper right of the GraphWorX screen to switch to the runtime mode or to open the display in a web browser . The runtime screen displays the current value for the OPC UA tag mapped in the previous steps.
