Go to and send the updated project to the HMI via USB or Ethernet. Select Overwrite when prompted.
To avoid critical downtime caused by locked HMIs in the future, implement a strict security management workflow.
Modern Pro-face HMIs supporting advanced web server capabilities or running Windows-based runtimes (like the Pro-face Blue or IPC series) can integrate with central user management systems. This allows passwords to be managed globally, removing reliance on hardcoded local passwords. Conclusion
Pro-face Human-Machine Interfaces (HMIs) are the backbone of modern industrial automation, trusted worldwide for controlling complex machinery. To protect proprietary PLC logic, operational formulas, and system configurations, developers implement security passwords on these devices. proface hmi password unlock
Ensure you are using the correct version (GP-Pro EX vs. GP-PRO/PBIII) as password protocols differ.
: 1101 is the most common system default. Others include 101 , 1111 , or 0 .
Confirm the command to wipe the current runtime project, internal logs, and security passwords. Go to and send the updated project to
This method requires you to have access to a working copy of GP-Pro EX that matches the HMI’s firmware version. If you don't have the software, you cannot create the drive.
HMIs often bridge the gap between corporate IT networks and physical plant floor machinery. A weak or easily cracked HMI password means an unauthorized actor could modify critical machine thresholds, leading to equipment damage or safety hazards. Recommendations for Future Project Deployments
This password is set in the GP-Pro EX project under Remote Viewer or Web Server settings. To protect proprietary PLC logic, operational formulas, and

now supports up to 15 different access levels for 100 individual operators. To prevent future lockouts, plants are increasingly using: Pro-face by Schneider Electric 23.10.1.1 Password Settings
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
