Mcgs Hmi Password

Common default/system passwords (historical MCGS units):

System boot password:     111111  
Project upload password:  888888  
Silent restore password:  6  
Engineering mode:         000000  
Download auth:            (blank) or 111111  

(Verify exact behavior with your specific firmware version as recent updates may change behaviour.)


| Level | Role | Access | |-------|------|--------| | 0 | None | No login – view only | | 1-2 | Operator | Run machine, view data | | 3-5 | Supervisor | Modify setpoints, clear alarms | | 6-8 | Engineer | Change recipes, calibrate sensors | | 9 | Administrator | User management, system config |

MCGS HMI panels are widely used in industrial automation but frequently deployed with default passwords unchanged. This creates a critical vulnerability. Organizations must enforce password policy, restrict physical access, and consider upgrading to newer models with improved security, such as login lockout and password complexity.

Managing passwords on an MCGS HMI (Kunlun Tongtai) involves several distinct security layers, ranging from factory-level access to project-specific user permissions. Because these devices are frequently used in industrial automation, security is tiered to prevent unauthorized machine operation or project modifications. Common Default & Factory Passwords

If you are locked out of system-level settings or performing a factory reset, these standard codes are often used:

Factory Access Code: 40721 is a documented factory password used during system resets or language changes.

Common Industry Defaults: If the factory code does not work, common fallback passwords for industrial panels include 111111, 123456, or leaving the password field blank. Password Protection Types (Verify exact behavior with your specific firmware version

In the MCGS configuration software (MCGS embedded version), there are typically three types of password protection:

Project Upload/Download Password: Protects the compiled project file. Without this, you cannot "read back" the program from the HMI to a PC or overwrite it with a new one.

Screen/User Access Passwords: Set within the HMI application itself. Designers use these to restrict specific buttons, navigation to sensitive screens (like "Settings" or "Calibration"), or modification of PLC parameters.

VNC/Remote Monitoring Password: Required if you are accessing the HMI via a network using a VNC viewer or the MCGS Debugging Assistant. How to Reset or Manage Passwords | Level | Role | Access | |-------|------|--------|

If a password has been forgotten, the recovery path depends on the level of protection: Troubleshooting Password Protection on Chinese MCGS HMI
