Hello,
My concern is that I can’t write values ​​on some tags. Indeed, even using UAExpert, I manage to write on some tags and others not. Those to which I cannot write keep their initial values ​​before my attempt to write, or the two types of tags have the same access (write access via OPC) and the same in the PLC, we can write to these variables.
I would like to have your opinion on this situation and how to solve this problem.

Thank’s

You need to check the server side if it allows writing to these tags.

I had checked and I had writing rights. The problem arose from the fact that these tags were copying variables from the PLC and not own variables having an address in the PLC.
Thank you
