- Click View Data to see your data in the Data Browser.
- Now you are connected to the OPC DA server.
- Next we will connect the OPC UA client.
- In the DataHub Properties window, select the OPC UA option.
- Make sure the box for Act as an OPC UA Server is checked, and the protocols you need are also checked. Then click Apply.
- To enable remote connections, select Security and then click the Configure button.
