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.
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 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
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 this screen wasn't built into the project,
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
You can assign a numerical value (0–999) to different buttons or screens. A user must log in with a password associated with an equal or higher authority level to press that button. If the original programmer set up user levels (e
MCGS uses a "Security Strategy" system. It is not just about one password; it’s about :
(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 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:
