For older S7-200 models (non-SMART) and very early SMART CPUs, there exist direct decryption tools. These older tools could connect via the PPI port and actually the password from the CPU's memory rather than just clearing it. Tools like "西门子PLC解密软件.rar" specifically target S7-200 CPUs (models 212, 214, 224, etc.) and claim to read the system and subroutine passwords directly, though they are typically limited to versions below 2.0.
