In this video, we demonstrate a practical OPC UA implementation using Python, with real Read & Write interaction using Node-RED as the OPC UA client.
You will learn how to:
Enable Read and Write access on OPC UA variables
Connect Node-RED as an OPC UA client
Read values from the server and write values back in real time
Simulate an industrial process (Tank filling with a Valve and FlowRate)
This video is perfect for automation engineers, industrial developers, students, and anyone who wants a hands-on understanding of OPC UA in a real industrial context.
The demonstration is done using:
Python OPC UA Server
Node-RED OPC UA Client
