Mcgs Hmi Password Work May 2026
For MCGS (Kunlun Tongtai) HMIs, passwords typically secure different levels of access, such as system settings, project uploads, or FTP servers. If you are locked out, you can try standard factory credentials or use specific software-based recovery methods. Common Default Credentials
Factory Password: 40721 (often used for internal system recovery or factory menus).
FTP Server: admin / admin (default username and password for port 21 access).
System Settings: 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
If default passwords fail, you may need to use MCGS Studio or physical access to reset the device: Project Upload (Bypass): Launch MCGS Studio on your PC. Go to Tools (工具) → Upload Project (上载工程).
Connect via Ethernet (default IP is often 192.168.1.200) or RS-232.
If the HMI is in download mode or not fully locked, you may be able to retrieve the project file to view or change passwords. USB Recovery Procedure:
Prepare a USB drive with the necessary recovery files (often named CHgstart or similar). Insert the USB into the HMI and restart.
Follow the "Recovery Wizard" (恢复向导) prompts to reset the registry or software shortcut. ADB / USB Debugging:
For models with a USB Type-B port, you may be able to use ADB (Android Debug Bridge) to access the internal filesystem and manually extract or delete the password-protected .MCE project files.
Caution: Avoid downloading "password cracking" tools from unverified sites, as these are frequently used to deliver malware to industrial control systems.
Are you trying to recover a project from the HMI, or do you just need to bypass a login screen on the unit itself?
4. Runtime Operations: Logging In and Out
How does the user actually enter the password on the HMI screen during operation?
3. Internal Logic: How the HMI "Thinks"
When you implement the above, here is what happens inside the MCGS processor:
- The Global Variable: The system tracks a hidden variable called
CurrentUserandCurrentUserLevel. - The Check: Every scan cycle, when an operator presses a button with a "Min Level" of 10, the HMI compares
CurrentUserLevelagainst10. - The Action:
- If
UserLevel >= 10-> Execute the button script. - If
UserLevel < 10-> Do nothing (or trigger an "Access Denied" popup).
- If
Summary
MCGS password work revolves around the Engineering Password (protecting your code), System Password (protecting the runtime), and Download Password (protecting the hardware). Proper configuration ensures operational safety and IP security. However, because password recovery is intentionally difficult for security reasons, rigorous documentation and backup procedures are essential for any MCGS engineer. mcgs hmi password work
(Kunlun Tongtai) devices, passwords are used for both project protection and system-level access. In many industrial applications, "factory password"
or default system password is used during initial setup or after a factory reset to regain control Default & System Passwords Factory Default Password
: The commonly cited factory password for MCGS HMI systems is
. This is typically entered when prompts for "factory password" appear during a restart or system change. User Management
: MCGS software (such as MCGS Embedded or MCGS Pro Designer) supports role-based user security . By default, the username
often has no password unless set during the initial configuration. Password Management and Reset
If you are locked out or need to change a password, the following methods are typically used: Entering System Settings
: During the boot process, pressing and holding the screen can sometimes trigger access to system settings Factory Reset
: If the project-level password is lost, you may need to reset the device to its factory state.
: This often involves a specific "tap sequence" or holding the screen during startup. : Resetting to factory defaults will typically erase the current project data Software Configuration : Within the MCGS configuration software MCGS Pro Designer ), passwords can be set or changed by navigating to the "Security" "User Management" settings in the project tree. Troubleshooting Access Issues Invalid Attempts
: Some HMI systems, like the Siemens Unified panels often compared in automation forums, may lock users out after several invalid attempts. Chinese Interface
: Many MCGS HMIs default to a Chinese language interface. You can often find a "Change Language"
option in the settings menu (using the 40721 password) to switch it to English for easier navigation. Official Resources

MCGS HMI password systems (MCGS Embedded) typically utilize three layers—project upload/download, runtime application, and system/control panel protection—which are managed through the software's "User Manager" or script-based triggers. While password recovery may involve uploading projects to check credentials or resetting to factory defaults, these procedures often require specific Chinese-language software environments. For a detailed guide on recovery and software, see the technical discussion on PLCTalk.net Industrial Monitor Direct
For MCGS HMI (Monitor and Control Generated System) devices, the standard factory password is 40721. This password is often required when accessing system-level settings, changing languages, or performing firmware updates via USB. Password & Security Configuration Report 1. Core System Passwords Factory Default Password: 40721.
Purpose: This is used to enter the system maintenance interface, modify the startup shortcut (GD5000), or adjust hardware-level parameters. 2. Project Security Management
In the MCGS configuration software, security is managed through levels and specific project settings:
User Permission Levels: You can define different security levels for operators, maintenance staff, and administrators.
Screen/Button Protection: Each screen or action button (like "Start" or "Settings") can be assigned a security level. If a user's logged-in level is lower than the object's level, the HMI will prompt for a password.
User Database: Usernames and passwords are often stored in a local database file (sometimes an .mdb or similar format) created during the project design phase. 3. Common Troubleshooting
Password Prompt on Startup: If an unknown password screen blocks access immediately, it was likely set by the original application developer. There is no "master" bypass for application-level passwords without the original project file or vendor assistance.
USB Updates: To update or "burn" a program via USB, you must often use the CHgstart program in the root of the USB drive and enter the factory password (40721) when prompted during the restart process. 4. Software Requirements
Environment: MCGS software is primarily designed for Windows environments. Some Chinese versions may have compatibility issues on non-Chinese (e.g., North American) Windows versions without locale adjustments.
Official Support: Technical documentation and software updates are available through hmitech.com.
Are you trying to recover a lost application password or just access the system settings? Troubleshooting Password Protection on Chinese MCGS HMI
MCGS HMI Password Management Report This report outlines the procedures for managing user access and passwords within the MCGS (Kunlun Tongtai) HMI environment. Proper password configuration is essential for protecting operational controls and preventing unauthorized project modifications. 1. User Level and Password Configuration
Security in MCGS is typically handled through a hierarchical user-level system that restricts component access based on privilege levels. The Global Variable: The system tracks a hidden
Accessing Settings: Navigate to Settings → System Settings → User Level in the MCGS configuration software.
User Count & Levels: 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.
Level 0 is traditionally set as "empty" for unrestricted basic access.
Component Protection: To protect a specific button or input field, open its Properties, go to the security/enable tab, and set the minimum required Password Level (e.g., 1–16). 2. Project Upload & Download Security
To prevent unauthorized users from extracting or overwriting the HMI project, separate communication passwords can be established.
Upload Protection: When attempting to retrieve a project from an HMI via Ethernet or RS-232, the MCGS Studio software will prompt for credentials if an application-level password is active.
System Settings Password: Accessing the HMI's internal system menu (often hidden behind an arrow icon or requiring a power-on gesture) usually requires a default password, such as 111111 or m1111111. 3. Password Recovery and Reset Methods
If credentials are lost, several recovery or reset methods are available depending on the HMI model and firmware.
USB Backup/Restore: Some models allow for system updates and program overrides using a USB drive containing a tpcbackup folder and specific decompression scripts. Factory Reset (DIP Switches): Flip DIP switch 1 to the UP position and cycle power.
Follow on-screen calibration prompts to reach the "Restore to default password" dialog.
Warning: This often erases the existing HMI program and resets the system password to 111111.
Software Workaround: If you cannot run the Chinese MCGS software on North American Windows, use tools like Locale Emulator or a Windows XP/7 Chinese edition in a virtual machine (VMware/VirtualBox) to successfully access project security settings. 4.
