OPC UA Real time trending tool - open sourced

Hello all,

Today GPT-5 was released and to try it out I decided to “develop” something I miss from studio5000, a convenient real time trace tool.

I (GPT-5) made an application that can browse the OPC-UA server on a B&R PLC or other device and display the values in real time.

There’s of course limitations and it does not replace the integrated trace tool since its not deterministic but I think it could be a great tool for monitoring processes, systems and regulators.

I made the application using electron + vite + ts. So you can build it as a windows application or launch it as a website (with some modification using mappConnect) on the PLC’s webserver during commissioning?

GPT-5? And developers can be fired :slight_smile: Just kidding, I tagged it toolkit, so it is visible in our toolkits channel :slight_smile: Thanks for sharing, and looking forward to feedback from others…

Hello @carl.hidestal

First of all, thank you for this helpful approach. I think this kind of feature should be available in all AS versions by now. As you mentioned, the tool isn’t as efficient as integrated tracing because there are some limitations and external factors like OPC UA latencies. But, it’s definitely a great tool for tracing without connecting to AS and if it’s supported by B&R, it could go even further, Congratulations :clap:

Greetings,
Hakan
