Never rely on the HMI as the only storage for the project file. Always keep the .dkp or .dop file on:
Delta Hmi Password Unlock Software is a powerful, specialized tool for industrial automation professionals. It is the difference between an hour of downtime and a week of waiting for an RMA.
However, it is a scalpel, not a hammer. It requires technical understanding of serial communications, bootloaders, and the specific HMI model. For the unprepared user, it poses a risk of permanent damage.
Final Recommendations:
Don't let a 8-character string hold your factory hostage. Understand your options, respect the IP of others, and use Delta HMI password unlock software responsibly.

Before discussing unlocking methods, it is essential to understand why Delta implements security.
The security is robust. Delta HMIs typically use a 8-character alphanumeric password hashed via a proprietary algorithm. When you lose the password, you cannot download a new program, upload the existing program, or change critical system settings.
Step 1: Identify HMI Model Check the back sticker. Ensure it is DOP-B (e.g., B07S410, B10S615). This will not work on DOP-100.
Step 2: Hardware Connection Connect your PC to the HMI’s COM port (usually COM1 – RS-232). Use a 2-3-5 pin null modem cable. Do not use Ethernet; these tools rely on serial communication.
Step 3: Enter System Mode Power on the HMI. During boot, tap the top-left and top-right corners of the screen (or press and hold the "System" button if available) to enter the HMI’s System Setting menu. Navigate to "Transmission Settings" and set the COM port to the correct baud rate (usually 115200). Never rely on the HMI as the only
Step 4: Run the Unlock Software Open the third-party software as Administrator. Select the correct COM port number. Click "Read Password" or "Unlock Project."
Step 5: Interpretation
Step 6: Upload the Project
Once unlocked, immediately open DOPSoft software (official) and upload the .dkp file from the HMI to your PC for backup.
This is the most common method used by professional "Delta Hmi Password Unlock Software." It involves placing the HMI in a special boot mode (usually by shorting specific pins on the motherboard or holding the touchscreen during power-up). The software then reads the raw flash memory, locates the password hash, and either decrypts it or deletes it entirely.
Delta has an undocumented (but legitimate) recovery feature. You can create a recovery file using DOPSoft or request a Reset.UPP file from your local Delta distributor. Don't let a 8-character string hold your factory hostage
How it works (Legitimate process):
Pros: 100% safe, no risk of bricking the device.
Cons: Total data loss. You will lose the HMI project entirely. You will need the original .dkp source file from your PC to reload the machine. If you don’t have the source file, this method is useless.
While Delta Hmi Password Unlock Software is a lifesaver in emergency scenarios, it is not without risks:
