TP1200 Profibus/MPI issue

[malc cope 1]

Hi Just wondered if anyone has come across this problem before? I have a TP1200 comfort HMI which for some reason refuses to change to Profibus connection, I can select Profibus and any node address but it always stays firmly as MPI, another identical unit I have is fine, the only real difference is that my application was originally downloaded into the unit I am having issues with using MPI

Try to transfer new image (firmware) to a TP. It commes with new version of TIA portal. Actual version is TIA Portal V11 SP2 Update2. Best regards.
