How can you with the opc-ua extractor read from the server only some specific tags with some parameter in the YML configuration file?
So far with this extractor all tags are sent to CDF.

Hi
Let me know if you have any more questions after reviewing these documentation links.

hi
Thanks for responding, I already saw that documentation, but I don't know what parameter in the yml file I should modify to read a tag from a controller, the following image shows the tag and node of the opc server.
Any idea what parameter to use so that the extractor sends itself:
ns=2, s=PLC.Device1.A252FIT022
