Human-Machine Interfaces (HMIs) are the window into industrial automation systems. Kunlun Tongtai’s MCGS (Monitor and Control Generated System) HMIs are widely used across manufacturing sectors to monitor programmable logic controllers (PLCs) and machinery. Protecting the intellectual property within the MCGS project file and restricting operational access on the factory floor are critical cybersecurity tasks.
Use the !GetPassword() function to create three levels:
If the defaults fail and you cannot upload or modify the project, you have two options: Software bypass or Hardware re-flash. mcgs hmi password
If you want to password-protect a particular screen (for example, a "Machine Parameters" or "Diagnostics" page) rather than the entire HMI, use the !LogOn() function.
Copy the runtime files from the HMI to a USB flash drive (if USB export is not locked). Use the
: Specialized automation shops offer "crack" or "unlock" services for various MCGS series, including the G, E, H, N, K, and T series (e.g., TPC7062, TPC1061). Software Bypass : In some cases, accessing the underlying Windows CE
If the upload password is lost and you do not possess a backup file on an external hard drive, the most secure and reliable path forward is to perform a Factory Reset on the HMI. This clears the encrypted memory entirely. You can then write and download a brand-new project file, ensuring full ownership and documentation of the new access credentials. 5. Best Practices for Industrial HMI Password Management : Specialized automation shops offer "crack" or "unlock"
: Opens a system dialog box prompting the operator for their Current Password , New Password , and Confirm New Password .
Use the MCGS "Export Data" function to keep a password-free backup of your historical data before attempting any system resets.
