The Verdict: Does It Actually Work?

Based on user testimonials across forums like PLCs.net, Reddit’s r/PLC, and MrPLC.com, the success rate is brand-dependent.

  • High Success (80-95%): Older legacy PLCs (Siemens S7-200, Mitsubishi FX1S/FX2N, Omron CPM1A/CPM2A, Delta DVP). For these, v4.2 is genuinely effective.
  • Moderate Success (30-50%): Mid-range units (Siemens S7-1200 firmware ≤ 4.1, Allen-Bradley MicroLogix 1100/1400 via DF1 port).
  • Low/Poor Success (<10%): Modern high-security PLCs (Siemens S7-1500 with password level 5, Allen-Bradley ControlLogix with FactoryTalk Security, any PLC encrypted via TPM module).

For cutting-edge hardware released after 2020, v4.2 is largely obsolete unless you are using a legacy compatibility mode.
