On engineering forums like PLCforum.uz.ua, users have shared a tool called "PLC HMI Password Unlock V4.2" designed to recover forgotten passwords on Delta PLCs and similar devices. One user tested the program on a Delta DVP28SV with a simple 4-digit numeric password (like 1314) and confirmed the software successfully recovered it. However, the same user noted that when tested with an 8-character alphanumeric password, the program ran for three days of scanning without success. FX1N, FX2N, FX3U series, and older GOT touchscreens
