To understand the tool, you must understand the S7-300’s protection model. The password is stored not in a separate EEPROM but within the protected system area of the MMC (Micro Memory Card) or the internal RAM of the CPU. Standard Siemens software (STEP 7 or TIA Portal) will never allow you to read this area without authentication. In most industrial contracts, the PLC program and
Siemens S7-300 PLCs use several levels of protection to safeguard industrial code and configuration:
