Large-scale AH500 series PLCs, designed for complex automation systems, incorporate more sophisticated security measures. The AH500 operation manual indicates that restoring the PLC requires the password, and after restoration, project passwords and program IDs may be recoverable while PLC passwords and PLC IDs cannot be saved within the ISPSoft project. This suggests password recovery on AH500 devices is more involved than on smaller PLCs.
