Most well-designed MCGS projects include a "Change Password" screen for operators. This is done using the !SetUserPassword() script command. !SetUserPassword("UserName", "NewPassword")

To enter the background calibration or IP settings menu, the default is usually 123456 . mcgs hmi password work
(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.
If you don't have the source code, try to "Upload" the project from the HMI to your PC. Note that if the "Prohibit Upload" checkbox was ticked during the initial download, you cannot retrieve the file without the specific Project Password . Most well-designed MCGS projects include a "Change Password"
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" ,
The password isn't hardcoded into the button; it is stored in a standard variable (e.g., UserPassword ). When you type on the keypad, the software compares your input to the value stored in the system database. 3. Recovering a Forgotten Project Password
If the original programmer set up user levels (e.g., Operator, Technician, Administrator), there is no "universal" default. However, many developers leave the Admin password as "1" or "888888" during testing.
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:
