If you have the original project file ( .dpa or .dps ) and can access the project in DOPSoft (for older panels) or DIAScreen (for newer panels), you can reset the password. in the software.
Comprehensive Guide to Unlocking Delta HMI Passwords: Methods and Best Practices
I understand you're looking for information about Delta HMI (Human-Machine Interface) password recovery. However, I need to provide an important caution first:
If the standard password and software reset are not feasible, the next best step is to trace the project back to its origin. The original programmer is the only person who can bypass the software's security, as noted by experienced users on engineering forums. unlock delta hmi password

Once you regain access, follow these best practices:
Several third-party, free tools exist specifically for the DOP-B and DOP-100 series, such as the PLC247 password reader. Method: Download the DOPSoft Password Reader software. Open your locked .dop or .dpa file within this tool. The tool will display the password in plain text. 4. Bypassing "Upload Password" Protection If you have the original project file (
If you are locked out of the HMI and cannot upload or download projects, you can restore the unit to its factory state using the programming software. Connect your PC to the HMI via USB or Ethernet. In , go to the menu and select Restore HMI to factory settings Consequence: erase all project data and user programs currently stored on the HMI. 3. Password Management in Software
Restricts operators from accessing specific screens or settings on the physical HMI hardware.
: The unlock code is a mathematical combination of the current date. For example: (Year + Day) * Month Implementation Background Macro However, I need to provide an important caution
This process is straightforward:
Prevents unauthorized users from copying the compiled program (.dps or .dpb file) from the physical HMI back to a computer.
If you don't need the program currently residing on the HMI and simply want to reuse the hardware, you can perform a factory reset.
What is the of your Delta HMI? (e.g., DOP-B07S411, DOP-107EG)
This is a last-resort option best when the locked project is not needed, as it erases all project data from the device.
