What or prompts do you see when trying to connect via STEP 7-Micro/WIN SMART?
Several third-party software tools are available for password recovery on S7-200 SMART project files and PLCs. These tools vary in functionality and legitimacy.
Siemens implements multiple layers of password protection on the S7-200 SMART platform. Users can configure security settings and passwords by selecting "Enable PLC Access Control - Enable PLC Protection (legacy access control)" in the PLC Security Setting panel. For Siemens S7-200 SMART V3.0, passwords must contain at least one lowercase letter, one uppercase letter, one number, and one special character, with a length between 10 and 63 characters.
The level of restriction depends on how the original project was configured in the settings:
Use a blank Micro SD card (or format an existing one to remove all files). Copy the S7_JOB.S7S file to the root directory of the card. The card should contain this file.
The is a third-party utility developed by the Chinese PLC technical community. It operates by directly communicating with the CPU's bootloader to perform sector-level erasure of flash memory.
The behavior of the "unlock" depends on the protection level set in the System Block > Security S7-200 Password - SiePortal - Siemens
These tools remove passwords from project files stored on disk, not from the PLC itself. They are useful when you have a saved project on your computer but have forgotten its password.
If you don't need to save the existing program and just want the hardware back to a "clean" state, use the method. Connect your PC to the PLC using STEP 7-Micro/WIN SMART . Navigate to the PLC menu and select Clear .
