OPC UA connectivity

Post by aliraza » Thu May 26, 2022 12:58 pm

Hi,
is it possible to create OPC UA client with the help of micropython. Currently, I'm trying to find a module that can enable me to make opc ua client.

I'm sure it's possible, but I don't think anyone has done it yet.

OPC-UA is what happens when you release german Diplom-Ingenieurs and just let them do what they want. It's rather complex.
There is a Python implementation. I have no idea how difficult it would be to adapt to Micropython. I suspect you will have quite a lot of work ahead of you.

The solution I use is to run a program on a computer on the same network, that functions as an OPC-UA client and as webserver. So my microcontroller projects just exchanges JSON files with this middle-program.
