How do I set a password for projects on HMI? - Delta Electronics

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.

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. unlock delta hmi password

Why Do Delta HMIs Have Passwords?

Before discussing how to unlock a Delta HMI, it is crucial to understand why the locks exist. Delta implements security on two primary levels:

Project File Protection (.dvp or .dop files): When an engineer creates a project in Delta's Screen Editor software (DOPSoft), they can set a password to prevent unauthorized reading, writing, or uploading of the program. This protects the Intellectual Property (IP) of the machine builder.
Runtime Screen Protection: During operation, the HMI may have user-level passwords (e.g., Operator, Supervisor, Engineer) to prevent untrained personnel from changing critical machine parameters.

When users search for "unlock," they usually mean one of two things: bypassing a lost screen access password on a running machine, or recovering/uploading a project file from an HMI when the source code is lost.

Step 4: Upload the Project (If Not Password-Locked for Upload)

Some Delta HMIs have separate passwords for “Operation” vs. “Upload/Download”.

Connect a USB cable or Ethernet (depending on model).
In ScreenEditor, go to HMI → Upload.
If the upload password is different from the run password, you might be able to retrieve the project without knowing the run password.
Once uploaded, open the project in ScreenEditor and disable or view the password under System Parameters.

Step 5: Last Resort – Contact Delta Technical Support (With Proof of Ownership)

If none of the above work, Delta can sometimes generate a master reset file. You will need:

HMI model number (e.g., DOP-107BV)
Serial number
Proof of purchase or a letter from your company on letterhead verifying ownership

Contact your local Delta distributor or open a ticket at Delta Global Support.

Step 1: First—Try the Default Passwords

Before attempting any reset, test the factory defaults. Delta HMIs often ship with one of these:

| Username (if prompted) | Password | |-----------------------|----------| | (blank) | (blank) | | (blank) | 111111 | | ADMIN | 111111 | | admin | (blank) |

What NOT to Do

Don’t brute-force the HMI via the touchscreen—it has no such function and you’ll waste time.
Don’t download random “unlock tools” from forums—they often contain malware.
Don’t short pins or attempt hardware hacking unless you are an electronics engineer and own the device.

If you have the original .dvp file but lost the password, open it in ScreenEditor, go to HMI → Compile → Decompile (advanced mode), and manually remove the password tag—but this requires deep familiarity with the file structure.

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:

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 unlock a Delta HMI password, you can

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.

Are you trying to unlock a specific project file on your PC or are you locked out of the physical HMI screen? Unlock HMI Security: Password Setup in Delta DOPSoft

Unlocking a Delta HMI password typically involves trying the factory default or using the hardware "System" button to access configuration menus. If you've forgotten a custom project password, you may need to factory reset the unit, which will erase the current application. 1. Try Default Passwords

Before attempting a reset, try the standard factory default passwords: 12345678 (Standard for project/highest security level). 00000000 (Common secondary default). 2. Access the System Menu

To change settings or passwords directly on the device, you must enter the System Menu: Locate the physical SYSTEM button on the back of the HMI.

Press and hold this button for 3 seconds while the device is powered on.

Alternatively, you can trigger the system menu by pressing and holding any corner of the screen during the initial boot-up sequence. 3. Reset or Bypass via DOPSoft

If you have access to the original project file in Delta DOPSoft, you can view or change the password: Open your project in DOPSoft. Go to Options > Configuration. Navigate to the Security Level and Password tab.

Modify the "Highest security password" or individual user levels. 4. Factory Reset (Last Resort)

If the project is protected and the password is lost, you must perform a factory reset to regain control of the hardware. Warning: This deletes the uploaded HMI program. Enter the System Menu (as described in Step 2). Look for System Setting or Init. Memory.

Select the option to restore factory defaults or clear memory.

How to Unlock Delta HMI Password: A Comprehensive Guide Forgetting a password on a Delta HMI (Human Machine Interface) can bring a production line to a standstill. Whether you’ve inherited a project without documentation or simply lost a long-standing code, "unlocking" the device is a common challenge for automation engineers.

This guide explores the legitimate methods to regain access, the differences between password types, and what to do when you’re truly stuck. 1. Understanding Delta HMI Password Levels

Before attempting to unlock a device, it’s important to know what you are actually trying to bypass. Delta uses several layers of security:

Screen Password: Prevents unauthorized users from switching screens or triggering specific buttons on the HMI during operation.

Upload Password: The most common hurdle. This prevents someone from pulling the project file from the HMI back to a PC.

System Menu Password: Protects the internal HMI settings (like IP address, COM port settings, and calibration). 2. Standard Methods to Recover Access Method A: The Default Password

If the HMI was recently installed or never properly configured, try the factory default. For many Delta DOP-B, DOP-100, and AS series models, the default system password is often: 12345678 88888888 00000000 Method B: Using Screen Editor / DOPSoft

If you have the original project file (.dps or .dpb) on your computer but can’t remember the password to open it: Open DOPSoft. Go to Options > Configuration.

Check the Control Block settings. Sometimes, the password is hardcoded into a register that you can view if the file isn't fully encrypted. 3. How to "Unlock" Without the Password (The Force Method) Why Do Delta HMIs Have Passwords

If you cannot retrieve the password and simply need the HMI to work again, your best (and often only) option is to overwrite the existing project.

Warning: This will delete the current program on the HMI. Do not do this if you do not have a backup of the original project.

Format the HMI: Enter the System Menu (usually by holding the "System" button on the back or a specific corner of the screen during startup). Select "Initialize" or "Format" to wipe the memory.

Download a New Project: Once the HMI is wiped, you can download a new software build via USB or Ethernet using DOPSoft. 4. Third-Party "Crack" Tools: A Word of Caution

You may find software online claiming to "crack" Delta HMI passwords by reading the hex dump of the memory.

Risks: These tools are often flagged as malware. Furthermore, newer Delta models (like the DOP-100 series) have enhanced encryption that makes these legacy cracking tools ineffective.

Legality: Always ensure you have the legal right to access the software before using bypass tools. 5. Preventing Future Lockouts

To avoid needing to "unlock" your Delta HMI again, implement these best practices:

Backup to USB: Use the DOPSoft "Copy to USB" function and keep a physical backup in a secure location.

Documentation: Record all passwords in a password management system or the machine’s electrical manual.

Disable Upload Password: If the environment is secure, consider disabling the "Upload Password" in the project settings to allow for easier maintenance.

Unlocking a Delta HMI usually comes down to either finding the documented code or initializing the unit and starting fresh. If the project inside is proprietary and you don't have the password, your best bet is to contact the original Machine Builder (OEM).

Requires reprogramming the HMI afterward
Check manual for specific model reset procedure

The Simplest Solution: Prevention

The best way to "unlock" a Delta HMI is to never lock yourself out in the first place. Implement these five best practices immediately:

The "Safe" Folder: On your company server or cloud storage, maintain a folder named HMI_Backups with the exact version of DOPSoft used and the .dop project file for every machine. Include a .txt file with the passwords.
Document Passwords in an Offline Vault: Use a password manager like KeePass (offline, encrypted) stored on a maintenance USB drive inside the electrical cabinet.
Use a Standard Password Policy: For runtime access, use a simple, documented tiered system (e.g., 1111 for Operator, 2222 for Supervisor). This is for convenience, not security against espionage.
Leave a Backdoor in the Code: As a programmer, add a hidden "Maintenance" button or a time-limited access code that resets the password for 60 seconds. Document this in the machine manual.
Label the HMI: Place a small, tamper-evident sticker inside the electrical cabinet door stating: "Delta HMI Project Password: [XXXX] – Upload Enabled: YES"
