If you cannot open the .mcgs file on your computer:
Double-click the target object (e.g., a "System Settings" button). Go to the or Security tab.
: Configure up to 16 user levels. Higher levels (e.g., Level 2) automatically inherit the privileges of lower levels (Level 0 and 1). Password Constraints : Passwords are restricted to numerical digits only. The maximum length for a password is eight digits .
For safety, it is best practice to log the user out automatically after a period of inactivity.
This article provides a comprehensive technical overview of how the password mechanism works in MCGS HMI software (MCGS Embedded Version / MCGS Pro), how to configure it, and how to handle common security challenges. The Core Architecture of MCGS HMI Security

: Some users report success by using a USB drive to manually copy folder structures like GD5000 to the HMI's internal storage to bypass certain software locks, though this requires technical expertise and the correct file structure. Best Practices for Password Management
If the HMI uses standard WinCE-based firmware, some generic defaults like 888888 or 111111 are sometimes used, though these are more common on rival brands. Password Recovery Methods
40721 (often used for internal system recovery or factory menus).
Required to open or edit the original project file in the MCGS configuration software.
: When designing an HMI project, each object (like a button or numeric input) has a "Security" or "User Level" property. If a user's logged-in level is lower than the object's requirement, the button will either be hidden or non-functional. Password Management
To prevent unauthorized bypasses while avoiding permanent lockouts, engineering teams should implement robust operational protocols:
This content covers the standard "System Password," the specific "Download/Upload Passwords," and how to handle lost password scenarios.
