Verifying OPC UA Connection with Data Tags

After establishing an OPC UA connection and adding some data tags, you can verify the connection using several methods, each having its advantages. You can use the following tools:

  • Data Browser: View the connection details in Workbench immediately after applying the settings. Learn more
  • Data Explorer: View the values of the OPC UA tags. Learn more
  • GraphWorX: View the current value of the selected OPC UA tag in a GraphWorX display. Learn more

To set up a connection that can be verified, you need to do the following:

  • Configure an OPC UA Server (in this example, DeviceXPlorer OPC Server). Learn more
  • Create an OPC UA connection, configuring it in Workbench. Learn more
