Start the tool and select the field Enter connection address. Fill in the address and port to the OPC-UA Server (i.e. the IP Address of the PLC and the default Port 4840). Next, click on the arrow and open the connection to the OPC-UA server.

Hint

A PLC might need to be in running mode for the OPC-UA server to be enabled.

Now you can browse through your OPC-UA Objects and search for the variables your OPC-UA server exposes. It is also possible to subscribe to data changes of variables.
