If you successfully recover a password, document it immediately in the physical electrical cabinet and migrate the logic to a modern S7-1200 system to ensure future-proof security and support. If you'd like to narrow this down, let me know: Do you have the PC/PPI cable and a physical COM port ?
A common issue among engineers is assuming there is a "default" password. According to official Siemens documentation , If a block is protected, it was set by a user during development.

that extract the password from the Micro Memory Card (MMC) and software-based crackers
firmware versions, passwords were sent over the network or stored in internal memory blocks using weak hashing mechanisms or plain-text buffers. Unofficial tools attempted to: If you successfully recover a password, document it
