In this article, we will explain the different types of passwords and protection that Siemens S7 200 PLC offers, and how to crack them using various methods and tools. We will also give you some tips on how to avoid losing your password in the future and keep your PLC secure.


Types of Passwords and Protection in Siemens S7 200 PLC




Siemens S7 200 PLC allows you to set three types of passwords and protection to prevent unauthorized access or modification of your program and data:


  • Project password: This is a password that you can set in the MicroWin software to protect your project file (.mwp) from being opened or edited by anyone else. You need to enter this password every time you open the project file in MicroWin.



  • PLC communication password: This is a password that you can set in the System Block of your PLC to protect your program and data from being read or written by any other software. You need to enter this password every time you communicate with the PLC using MicroWin or other software.



  • Subroutine password: This is a password that you can set in the Properties of each subroutine in your program to protect your code from being viewed or edited by anyone else. You need to enter this password every time you open or edit the subroutine in MicroWin.



Each type of password has its own purpose and level of protection. However, none of them are unbreakable. There are ways to crack them and unlock your PLC.


How to Crack Project Password of Siemens S7 200 PLC




The project password is the easiest one to crack, as it is stored in the project file itself. You can use a tool called datamanagers200.dll to bypass the project password and open the file without entering any password.


To use this tool, you need to download the datamanagers200.dll file that corresponds to your MicroWin version (SP8 or SP9), and copy it to the MicroWin installation directory (C:\\Program Files\\SIEMENS\\STEP 7-MicroWIN V4.0\\bin). Then, you can open any project file without entering a password.


How to Crack PLC Communication Password of Siemens S7 200 PLC




The PLC communication password is harder to crack, as it is stored in the PLC memory itself. You cannot use any software tool to read or write the PLC memory without entering the correct password. However, you can use a hardware tool called PPI cable to reset the PLC memory and erase the password.


To use this tool, you need to connect the PPI cable between your PC and your PLC, and select the correct communication port in MicroWin. Then, you can use the Decryption function in MicroWin to read the password from the PLC memory and display it on your screen.


Note that this method will also erase all your program and data from the PLC memory, so make sure you have a backup before using it.


How to Crack Subroutine Password of Siemens S7 200 PLC




The subroutine password is the hardest one to crack, as it is encrypted in both the project file and the PLC memory. You cannot use any software or hardware tool to view or edit the subroutine code without entering the correct password. However, you can use a service called PLC Unlock BD to decrypt the subroutine code and send it back to you.


To use this service, you need to send them your project file (.mwp) or your PLC backup file (.bin) via email or WhatsApp. They will decrypt the subroutine code and send it back to you within 24 hours. They charge a fee for this service, depending on the number of subroutines and their complexity.


How to Avoid Losing Password of Siemens S7 200 PLC




The best way to avoid losing your password of Siemens S7 200 PLC is to keep a record of it somewhere safe and accessible. You can write it down on a paper or store it in a digital file, but make sure you don't lose it or forget it.


You can also use some features in MicroWin to help you remember or recover your password:


  • Password hint: You can set a hint for each type of password in MicroWin, which will be displayed when you enter a wrong password. The hint can be anything that helps you recall your password, such as a question, a clue, or a mnemonic.



  • Password recovery: You can set an email address for each type of password in MicroWin, which will be used to send you a recovery code if you forget your password. The recovery code can be used to reset your password and access your project file or PLC.



These features are optional, but they can be very useful if you tend to forget your passwords.
