Most well-designed MCGS projects include a "Change Password" screen for operators. This is done using the !SetUserPassword() script command. !SetUserPassword("UserName", "NewPassword")
If you are locked out of an MCGS HMI project, "recovery" is difficult because the software compiles files into a binary format. Here are the common workarounds:
To enter the background calibration or IP settings menu, the default is usually 123456 . mcgs hmi password work

If you simply need the hardware to work and don't care about the existing program, you can perform a factory reset via the SD card or USB recovery mode. This will wipe all data, including the password and the project. 4. Changing the Password during Runtime Most well-designed MCGS projects include a "Change Password"
Are you trying to bypass a on a physical machine, or
If this screen wasn't built into the project, you cannot change the password while the machine is running; you must modify the project in the MCGS software and redownload it. 5. Best Practices for Engineers To avoid "password lock" issues in the future: of the original .mcg project file. Here are the common workarounds: To enter the
MCGS uses a "Security Strategy" system. It is not just about one password; it’s about :
MCGS (Monitor and Control Generated System) HMI panels are widely used in industrial automation, but managing passwords can be a hurdle during maintenance or when inheriting a project from another engineer. This guide covers how passwords work across different layers of the MCGS ecosystem. 1. Default Passwords and Levels
(Kunlun Tongtai) are typically "123456" or "000000" , depending on whether you are accessing the runtime environment, the system settings, or the configuration upload/download functions.
