Delta PLC & HMI Password Unlock and Project Recovery Service | PLC Cracker
Locked Delta PLC or HMI? We recover DVP PLC program passwords and DOP HMI upload passwords, disable Prevent Upload, and restore your project. Remote support available.
A machine stops. The program inside the PLC or HMI is locked with a password nobody remembers. The original programmer has left, the backup file is lost, and the production line cannot wait. This is one of the most common problems in factory automation — and it is exactly the problem our PLC HMI Helper service solves for Delta devices.
We provide professional Delta PLC password unlock and Delta HMI project recovery support, so you can read, edit, back up and re-download your own machine program again.
Delta PLC (DVP Series) — Program Password Unlock & Project Recovery
Supported DVP models include:
- DVP-14SS2
- DVP-32ES2
- DVP-20SX2
- ES2 / SS2 / SA2 / SE series
- EH3 series
- SV2 series
For these PLCs we support program password unlocking and project recovery, so a password-protected program is no longer a dead end when you need to modify a machine, replace a damaged CPU, or create a safe backup of a running line.
Delta HMI (DOP Series) — Upload Password Recovery & Prevent Upload Disable
Supported DOP models include:
- DOP-B07S411
- DOP-B05S100 / DOP-B05S101 / DOP-B05S111
- DOP-B10S411
- DOP-B03S211
- DOP-100 series: DOP-103 / 105 / 107 / 108 / 110 / 112 / 115
For these panels we support upload password recovery — reading back the project that is already running on the panel — and Prevent Upload disable, so a protected project can be uploaded, backed up and edited in DOPSoft again.

Frequently Asked Questions
Can you unlock any Delta PLC or HMI password?
Support depends on the model and protection type. The DVP and DOP models listed above are our regular working range — send us your model number and we will confirm before starting.
Will my machine program be changed?
The goal of project recovery is to give you back access to your existing program so you can back it up and edit it. We explain exactly what will be done in your case before we start.
Do I need to send the device to you?
Not always. Many recoveries are completed remotely with the project file or a firmware dump. If hardware access is required, we will tell you in advance.
Which other brands do you support?
Besides Delta, we work on Siemens, Mitsubishi, Panasonic and Omron PLC and HMI password and project recovery.
