I noticed you are very proficient regarding the subject so i decided to ask.
tried using ollidbg but got dizzy.
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.
- When creating logic blocks (OBs, FCs, FBs), you can declare temporary local data. The local data area on the CPU is divided among the priority classes. On S7-400, you can change the amount of local data per priority class in the 'priority classes' parameter block using STEP 7.
- 'Bind to Serial Number of the PLC' - This setting will allow a block to be bound to. Siemens Edition or Ultimate Edition; TIA Portal V13/14/15; S7-PLCSIM. Sorting by Height with S7-PLCSIM V13/14.
- Ofcourse the correct way is to have the source code, But as you know sometime Thats not possible. In this case the company that made the program as closed, and not possible to find and get the source files.
In case of programmed in statmentlist.Open the backup on your PC. Change to STL editor. Export the complete project. Open a new project in MW and import the file. Unlock protected block in Simatic Manager Siemens S7 PLC using Microsoft Access - Duration: 7:08. S7 Can Opener Keygen. TIA Portal V14 / SIMATIC S7-1500(T).
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.tried using ollidbg but got dizzy.

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
