Greetings.

I am not sure which password you are refering to.
As far as I know there are 3 types..

1. A password for the project / file.
> This can be set under FILE >> SET PASSWORD.
> The password is asked as soon as you open the MWP file in Microwin.
- Recovering the password will need someone to crack the file.
- (..maybe someone knows, but I doudt they'll share.)

2. PLC communication password.
> Privileges are set on the PLC hardware for read/write processes.
> The password it set in SYSTEM BLOCK under PASSWORD
- You do not need to hack the hardware if you have the original program. You can reprogram the effective PLC with the original program with a new password. You first need to wipe the PLC with a PLC reset (PLC >> CLEAR selecting all blocks).

3. Blocked subroutine.
> Read/Write access to a subroutine is set inside the "Properties" of the subroutine.
> The password guards the coding regardless if it is in hardware or pulled out onto the PC.
- The same commentary as in (1) applies.
- Siemens uses this method to guard coding that is auto generated by Microwin.

Which of the passwords did you refer to?
If you have the original (unblocked) MWP file and need to link to the PLC where password type 2 was used -- then there is a way. Otherwise a White Hat Hacker can not help you.

Please let us know if you think we can help further..

Hello,
  • It is not possible and not legal as well to break programmer password which he made to protect his software from un-autorized access. If you want to access the program, you have to contact the programmer and ask him for password.
  • A hill of threads talks about same subject in the last few years:
    PASSWORD
    s7-200 password
Hope this helps.

Hello,
Removing S7-200 battery won't break the password. Moreover there is any relationship between password and batteries of S7-200.

No sense to talk much about this, whatever type of password protection it is in S7 200,
The only thing is that you need original password, otherwise ready to reset PCU & download program backup if you have otherwise call any programmer to make a new program Rnf:lblSmileyTooltip_

Reply if not solved, RATE if solved....!!!!!!!

Happy to Help :)

The question comes up..
even if you knew how to crack a password; would you?
Would you want someone to crack yours?

Rather not do it.
At the end of the day -- your ethics is what you take home with you.

Hi sanyay ,

i agree with your answer if you want to erase whole logic then it will be useful and ready to lose password protected logic which is intention of password
