It seems impossible. As Siemens uses aes encryption, program will be only decoded in real PLC.

I do not know about TIA, as I do not encrypt my program. But für Step7 block privacy, programs are NOT decoded in plcsim.
So I do not believe TIA Portal plcsim will decode the program.

IF program save in internal storage, you can find password and upload project via read EEPROM.

Hi,
is there solution to unblock protected block in TIA?
I protected the blocks not only from others but from myself.
