Part 2: How to Unlock/Reset the HMI System Password (DOP Series)
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
Consider using (DIALink or WebAccess) which allows centralized password management and remote backup.
The most common hurdle. This prevents someone from pulling the project file from the HMI back to a PC.

Warning: This method will completely erase the old program running on the HMI. Only use this if you have a copy of the original program saved on your PC, or if you are completely reprogramming the machine from scratch. Method 4: Contact the Original Equipment Manufacturer (OEM)
: Instead of relying on a single "all-access" password, configure Delta’s multi-level security system to grant different permissions to operators, technicians, and administrators, reducing the risk of a single lockout crippling your entire operation.
If you have access to the original project file (.dps or .dpb) on your computer, you can modify security settings without needing to "unlock" the physical screen: Navigation: Open the project in Configuration Security Settings: Password Table
Ultimate Guide to Unlocking Delta HMI Passwords: Safe and Approved Methods Part 2: How to Unlock/Reset the HMI System
If the HMI was locked with an "Upload Password" during the original compilation, there is no direct software method to "crack" or "unlock" it via Delta software. The only way to regain functionality is to: Use the original project file.
Several third-party automation tools online claim to instantly crack Delta HMI passwords. How It Works Risk Level Recommendation
This comprehensive guide covers the official, safe, and technical methods used to handle locked Delta HMIs, along with the risks associated with third-party software. 1. Understanding Delta HMI Password Levels
How to Unlock Delta HMI Passwords: A Complete Guide Delta Human Machine Interfaces (HMIs) are widely used in industrial automation due to their reliability, affordability, and extensive communication capabilities. However, getting locked out of a Delta HMI—whether you forgot the password or inherited a machine without the documentation—can be a massive headache. I can provide the specific software tools or
If you lost the HMI’s upload password but still have the original project file on your computer, you can simply create a new download file without a password.
Delta Human Machine Interfaces (HMIs), such as the popular DOP-B, DOP-W, and DOP-100 series, are cornerstones of industrial automation. They offer robust performance for controlling PLC systems. However, security measures like project download/upload passwords or local menu restrictions can sometimes lead to lockout situations.
This completely erases the HMI. You will lose the password, but you will also lose the entire application. You will be left with a blank HMI requiring a new project download. This is only useful if you have the original .dop project file on a PC.
A: No. USB keyboards are only for data input, not bypassing security.
