OPC UA example

This is a simple OPC UA server, client, publisher and subscriber network example using C#/.NETv8 and the OPC Foundation SDK. It also contains a custom OPC UA model, written in XML and compiled with the UA-ModelCompiler.

How to run the example

1. Open OpcUaDemo.sln with Visual Studio 2022
2. Set SimulationHost as startup application
3. Get the connection details to your MQTT broker
4. Modify the MqttCommon/Config.cs (broker host/port)
5. Run the example

Additional tools

To get some insights of the OPC UA server, use a OPC UA browser like Prosys OPC UA Browser (there are many others).

To watch the mqtt stream, use a Mqtt client, such as MQTT.fx.
