I noticed you are very proficient regarding the subject so i decided to ask.
tip: block passwords in tia portal can ony be set in one session: if you close the block and reopen the button is greyed out.

The compiled code is known as blocks. The blocks are now protected which means the code inside the block can't be seen by other. Then delete the source and your blocks are now protected. Now my objective was to unlock those blocks. So I'd followed the steps given below to unlock those blocks, Step 1: Download.dbf file editor. And also how to unlock double password of Misubishi PLC??

My other approach was using content comparison between the project/system/PEData.idx(plf) files before and after intoducing/changing the password.

Scenario 2: you access a s7-1200 plc in a factory and need to modify the recipe parameters and add a fail-safe functionality to the existing program. The cpu is read/write protected and the function block is password protected. The whole soft is saved on the plc memory.

Most of the passwords are long so a brute force attempt would take alot of time.
