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
