Human-Machine Interfaces (HMIs) are the heart of industrial automation, allowing operators to monitor and control complex machinery. Pro-face, a global leader in HMI technology, utilizes robust security measures to protect intellectual property and prevent unauthorized configuration changes.
Use GP-Pro EX to modify the project settings and re-transfer the modified project to the HMI. 5. Summary of Actions Forgot Offline/System PW Initialize GP Memory Project data is erased . Forgot Project Transfer PW Edit Project in GP-Pro EX No data loss, requires software. Remote Viewer Locked Change Password in Offline Mode No data loss. 6. Pro-face HMI Password Security Tips To avoid future lockouts:
Enter the existing password, then leave the new "Password" and "Confirm" fields and click OK. proface hmi password unlock
Prevents unauthorized users from pulling the project file from the HMI to a PC. This is the most common "lock-out" scenario. Method 1: Using the Default Passwords
Keep holding until the screen appears. Navigate to Initialize Memory or Clear System Area . Human-Machine Interfaces (HMIs) are the heart of industrial
Implement a company-wide standard for background service passwords. While individual operator accounts should vary, the core upload/download administrative passwords should follow a secure, company-specific algorithm known to all internal automation engineers.
: Many downloadable "HMI crack tools" hosted on unverified forums contain trojans designed to steal intellectual property or infect industrial control PCs. Remote Viewer Locked Change Password in Offline Mode
If you know the current password but want to remove it, open GP-Pro EX and go to [Project] → [Information] → [Passwords] . Under [Send/Receive], enter the current password, then leave the new password fields blank and click OK. Important Considerations
Losing or forgetting the password to a Pro-face Human-Machine Interface (HMI) is a common crisis in industrial automation. Production lines stop, updates are delayed, and maintenance halts when you are locked out of critical system settings or project transfers.
specialize in "cracking" or reading the hex-encoded password directly from the HMI's memory. This process preserves the internal program, allowing the machine to stay in production. The "Administrative Reset" (Modern Units): Newer models like the STW6000 series
To avoid costly downtime caused by lost passwords in the future, engineering teams should implement a strict security and backup policy:
