Configuring OPC UA

The OPCUA.project project contains an application where variables are configured to access an OPC UA client. To do this, the two variables of the PLC_PRG object have been published in the Symbol configuration object.

In a suitable OPC UA client, such as Unified Automation UaExpert, you can connect to your RaspberryPi via the URL opc.tcp://<network address>:4840. In the client, its symbols (published variables) are displayed and the current values are shown. If write permission is granted in the symbol configuration, then you can write to the symbols.
