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...
- get "something" working. I suggest you use something like UA expert. Verify you can communicate with the PLC.
- Remove one of the libraries. Personally I'd keep the iiot-opcua library.
- 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.
