MP377 upload project file

[dsc 1]

Is it true that we can't upload a source file from MP377? I saw a 'backtransfer mode' in WinCC but not sure what it function. dsc

You can indeed upload from an MP377 into WinCC Flex. However, ONLY if the original programmer enabled the backtransfer option when he transferred the project to the panel, AND the flashcard that was installed in the panel at the time is still present.
