MCGS uses a "Security Strategy" system. It is not just about one password; it’s about :
If you have the source code ( .mcg or .mcp file) on your PC, you can open the User Manager in the MCGS development environment to see or reset the passwords.
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 . mcgs hmi password work
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
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 MCGS uses a "Security Strategy" system
Most well-designed MCGS projects include a "Change Password" screen for operators. This is done using the !SetUserPassword() script command. !SetUserPassword("UserName", "NewPassword")
in MCGS settings so the HMI doesn't stay logged in as an Administrator after a technician leaves the floor. Note that if the "Prohibit Upload" checkbox was
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.
