Create a blank project in GP-Pro EX matching the exact model number of your HMI. Download this blank project to the unit. This action erases the existing application along with its security constraints, resetting the HMI to factory default settings. 4. Technical Decryption and Hex Editing (Advanced)
If you have a backup of the original GP-Pro EX project file on your engineering laptop, the fastest solution is to completely wipe the HMI and reload the project. Wiping the memory clears the forgotten password.
Always store a copy of the password inside a secure text file alongside the master PLC/HMI source code in your engineering repository. proface hmi password unlock
Once you have successfully regained access to your Proface HMI, it is vital to implement practices to prevent future lockouts.
Reputable services like TMN SOFT offer an approach that is "no reset, no hardware damage". Their typical process involves: Create a blank project in GP-Pro EX matching
Use the "Information Label" feature in GP-Pro EX to leave contact info for the original programmer. Conclusion
If you don't need the data currently on the HMI and just want to get the hardware working again, you can perform a factory reset. Always store a copy of the password inside
The exact of your Pro-Face panel (e.g., GP-4501TW, AGP-3500).
It sounds simple, but many systems are left with factory settings. Before trying complex workarounds, test these common defaults: 0000 8888 Method 2: Recovery via GP-Pro EX Software
Given the severe security and reliability risks, using third-party password unlock tools is strongly discouraged.
Using non-official cracking software carries a risk of corrupting the HMI firmware or downloading malware onto your engineering PC. Always back up whatever data you can before trying these utilities. 4. The Last Resort: Factory Resetting the HMI
