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?? But there is no way to access a password protected program. Upvote (1) Downvote (0) Reply (0). In the system block you should now be able to select a new PW for this project. You now can change the program.

My other approach was using content comparison between the project/system/PEData.idx(plf) files before and after intoducing/changing the password.Passwords can be quite long so a brute force approach would be inconvenient.
Scenario 1: you have your designed software on your pc and you forgot the password of your ob1 function block.

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.
Here is a sample project with passwords all over it for a s7-1214 http://www.filehosting.org/file/details/390795/newp.zip
Most of the passwords are long so a brute force attempt would take alot of time.

the passwords are:
something like Passw0rdPr)tect or PasswordProtected for the processor
the main function: I actually forgot this one, should be a long string
Kn0wH)w for the datablock
'password' for Bleeper function
pa55w0rd for ownedscl function
