I have PI SDK application with get/set values functionality. I have PI Server on remote machine. I'm able to read values of PI Tags, but no write values. I'm using username/password authentication and on PI Server I have 30 days temporary license for now. I'm not sure if this kind of license is the reason why I cannot write values on remote PI Server. Server is 64 bit and client 32 bit, but I guess that it is not issue. Operation "set values" ended without any exception..
On my local PI Server it works fine! My local server has vcampus license.
