Hello everyone,
one of my customers wants to communicate with the OPC UA server of a B&R controller through a Windows application developed in VB.NET. Are there any recommended libraries that can be used in VB.NET to act as an OPC UA client for communicating with a B&R controller?
Are there any example code snippets available for this?
best regards from Friedberg
Hi, B&R OPC UA server follows the OPC UA Foundation standard. With that said, the OPC UA server does not care what programming language or platform is used for the OPC UA client, as long as the OPC UA Foundation specification is followed. So, long story short, from my perspective, you can use any OPC UA client developed in VB.NET. Maybe someone from BRCommunity has already had experiences or a VB.NET solution—happy to hear about it 
Hello,
I don’t know much about OPC-UA in Visual Basic.
What’s the purpose of the Win app? If it’s a trace tool for commissioning, someone in comunity already done this.
Since I made that post I tried to tool for commissioning and it works. Still missing a crucial feature, to scale each signal on the Y-axis. Im gonna add this whenever i have time. But if you cant wait you can pull the repo and fix yourself if needed.
Hi @yannick.gross have you found solution for your issue?Can you update us?
Since OPCua is an open standard, I have recommended this Git repository. I think that everything necessary can be done with it.
