I am monitoring a CPU with this firmware, and it was programmed with version 15.1 of TIA, but TIA 15.1 only has 4.0 and I can't upload the program.

Does anyone know the solution? Thanks

What options are available in STEP 7 (TIA Portal) for uploading when the project version in the CPU no longer matches the version on your PG/PC?
