Hi. Firstly, why have you created a new topic?

Also, didn't the last response say you seem to be using 2 different libraries? That won't work.

Here is my suggestion...

1. get "something" working. I suggest you use something like UA expert. Verify you can communicate with the PLC.
2. Remove one of the libraries. Personally I'd keep the iiot-opcua library.
3. Read the documentation and look at the examples. There are a few examples come with iiot-opcua. Look under the hamburger menu (top right), import examples.
