By using the methods outlined in this report, users can regain access to their Delta HMI device and continue to monitor and control their industrial processes. It is essential to follow best practices and take precautions to maintain system security and prevent unauthorized access.
To unlock a Delta HMI when the password is lost, you can attempt to use default credentials, access system settings via programming software, or perform a factory reset. 1. Try Default Passwords
Many Delta HMI models (like the DOP-B and DOP-100 series) ship with standard factory passwords. Try these common defaults first:
12345678 (The most common default for high security levels).
111111 (Common for local system settings on similar HMI brands). 2. Use DOPSoft Software
If you have access to the original project file or can connect to the device, use DOPSoft to view or change passwords: Connect the HMI to your PC using a USB or Ethernet cable.
Open DOPSoft and navigate to the System Parameter Settings (F5). Go to the Security tab and open the Password Table.
You can view, modify, or delete existing passwords for different security levels here.
Download the updated project back to the HMI to apply the changes. 3. Factory Reset (Last Resort)
If the project is protected and you cannot upload it, you may need to clear the HMI memory entirely. unlock delta hmi password
Wipe Memory: Using DOPSoft, you can often format the HMI system memory, which removes the current program and its password protection.
Caution: This will permanently delete the existing application. You must have a backup copy of the original program to reload onto the device afterward. 4. Third-Party Unlock Tools
There are specialized software tools (e.g., "Project Password Readers") advertised for Delta HMIs, but use them with extreme caution.
Security Risks: Many of these "cracking" tools found online are known to deliver malware or exploit zero-day vulnerabilities.
Official Support: If this is a critical industrial system, it is safer to contact the original programmer or Delta Electronics technical support for recovery assistance.

How do I set a password for projects on HMI? - Delta Electronics
The pursuit of a universal "Delta HMI unlock code" is largely a myth. While older DOP-B series had known backdoors (e.g., 575233), modern Delta HMIs like the DOP-100 series are built with robust security to protect machine builders' intellectual property.
If you are an end-user or maintenance technician, your realistic options are: uploading the project (if allowed), contacting the OEM, or performing a factory reset that erases the device. Attempting hardware-level hacks carries a high risk of destroying the unit.
Ultimately, the key to unlocking a Delta HMI is not a piece of software—it is documentation and communication. Secure your project files, document your passwords, and maintain a relationship with your machine builder. That is the only reliable way to ensure you never face a locked screen during a critical production shutdown.

Unlocking a Delta Human Machine Interface (HMI) typically involves either using known default credentials, resetting the device to factory settings, or employing specialized software to retrieve forgotten project passwords. 1. Default Passwords
Before attempting a hard reset or using unlocking tools, try the common factory default passwords. These are often used for local settings access and remote monitoring: Delta HMI Password Unlock Report Introduction Delta HMI
System Settings/Local Access: 111111 is frequently used for local configuration screens.
DOPSoft/eRemote: The standard default for many DOP series models is 12345678. 2. Password Retrieval for Project Files
If you have lost the password for a specific project file (e.g., .dps, .dpa, or .dpb), you may need to use a password "reader" or "cracker." These tools are generally third-party software designed to scan the project file and reveal the stored string.
DOPSoft Method: Some users use debugging tools like xdbg to find upload password verification strings within the software's binary.
Third-Party Software: Sites like PLC247 offer specialized "Unlock Key" software that claims to read these passwords for various Delta DOP series models. 3. Physical Factory Reset
If the system password is unknown and preventing all access, a factory reset is the final option. Note that this will erase all stored data and project files on the HMI.
Locate the physical "System" button or specific DIP switches (depending on the model, such as the DOP-B or DOP-100 series).
Hold the system button while powering on the unit to enter the boot menu.
Select the option to Restore Factory Defaults or Clear All Data. 4. Setting or Changing Passwords in DOPSoft
To prevent future lockouts or to secure your own projects, use the DOPSoft configuration menu: Navigate to: Options →right arrow Configuration →right arrow Security Level and Password. Enable Protection: Go to File →right arrow Password Protect to encrypt the entire project file.
User Levels: You can set different passwords for different user levels to restrict access to specific sensitive HMI screens.

Unlocking a Delta HMI password typically refers to one of three things: regaining access to the System Settings , opening a Protected Project File , or uploading a program from the HMI to a PC ( Upload Password 1. Default Factory Passwords
If the HMI is still using factory settings or you are accessing the system menu for the first time, try the standard default passwords: : The most common default password for Delta DOPSoft and project security. : Sometimes used for local system setting access
: An alternative eight-digit default used in some older DOP-A or DOP-B series units. Welcome to Delta 2. Accessing the HMI System Menu
If you are locked out of the HMI's internal configuration (IP settings, calibration, etc.), you can often bypass the user project to enter the System Menu: Physical Method
: Most Delta DOP series HMIs have a "System" button or a hidden touch sequence (usually holding the top-left corner during power-up) to enter the system settings. Maple Systems
: You can perform a factory reset from within this menu, though this will erase the current project stored on the device. 3. Unlocking Project Files (.dps, .dpa, .dpb) Method 1: Using the Default Password
If you have the project file but cannot open it in DOPSoft because it is password-protected: Official Recovery
: There is no "forgot password" button within the software. You must have the original password set during the configuration phase Third-Party Tools
: Some specialized technical services and "HMI Unlocker" software claim to read the project password from the file metadata. These are often used by maintenance engineers to recover programs from legacy hardware 4. Bypassing the Upload Password
If you are trying to "Upload" (suck the program out of the HMI into your PC) and it asks for a password: Security Level
: If the "Prevent Upload" option was checked by the original programmer, the HMI will not allow the program to be extracted at all, regardless of the password. PLC/HMI Sync : Note that the HMI password and PLC password
can be different; ensuring you are targeting the correct device is critical.

When you forget any of these, the HMI becomes a locked black box. You cannot modify the application, back it up, or even change basic network settings.
Delta Electronics is a global leader in industrial automation, and their Human-Machine Interface (HMI) panels—such as the DOP-B, DOP-100, and DOP-W series—are widely used in factories, process control, and machine building. These HMIs store critical operator screens, macros, recipes, and communication settings.
One of the most common (and frustrating) issues maintenance engineers and system integrators face is being locked out of a Delta HMI due to a lost or unknown password. Whether you inherited a machine with no documentation or a former employee left without handing over credentials, the need to unlock a Delta HMI password is urgent.
This article explains the legitimate methods to reset, recover, or bypass password protection on Delta HMIs, the risks involved, and best practices for avoiding future lockouts.
Delta’s DOPSoft (a configuration tool for DOP-xxMseries HMIs) can aid in password recovery if the original project file is available:
.DOP and export settings to retrieve password-protected screens.For newer models (e.g., DOP-xxExx, DOP-xxBxx), Delta’s HMI Designer or Delta Smart Designer tools may offer similar functionality. Visit the Delta website for software downloads and guides.
The best way to "unlock" a Delta HMI is to never lock yourself out in the first place. Implement these five best practices immediately:
HMI_Backups with the exact version of DOPSoft used and the .dop project file for every machine. Include a .txt file with the passwords.1111 for Operator, 2222 for Supervisor). This is for convenience, not security against espionage.
