Mcgs Hmi Password Work Portable [OFFICIAL]

Default passwords for MCGS HMI software (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.

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

In most MCGS TPC (Touch Panel Control) series, there are three primary areas where you will encounter password prompts:

System Setup (Control Panel): To enter the background calibration or IP settings menu, the default is usually 123456.

Project Runtime: 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.

Upload/Download: When transferring a project from a PC to the HMI via MCGS Embedded software, the default communication password is often empty (no password) or "123456". 2. How Password Permissions Work in MCGS

MCGS uses a "Security Strategy" system. It is not just about one password; it’s about User Groups:

Authority 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.

Password Variable: 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 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: mcgs hmi password work

Check the Configuration File: 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.

The "Upload" Method: 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.

Factory Reset: 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

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

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: Always keep a backup of the original .mcg project file.

Document the System Password on a sticker inside the electrical cabinet.

Use the "Auto-Logout" feature in MCGS settings so the HMI doesn't stay logged in as an Administrator after a technician leaves the floor.

Understanding and Managing MCGS HMI Passwords In industrial automation, the MCGS (Monitor and Control Generated System) HMI is a widely used interface for controlling machinery. Managing passwords effectively—whether for daily operation, program security, or emergency resets—is critical for maintaining both safety and system integrity. Common Default Passwords Default passwords for MCGS HMI software (Kunlun Tongtai)

For many MCGS TPC series models, certain factory-set credentials are often used during initial setup or for specific maintenance modes.

Factory/Engineer Password: 40721 is a frequently cited default for accessing deeper system configuration menus or changing language settings.

Generic HMI Defaults: While not universal across all Chinese HMI brands, many similar industrial panels use 111111 or 888888 for basic system access. Types of Passwords in MCGS HMI

The MCGS software (such as MCGS Embedded V7.7) allows for multi-layered security. You will typically encounter three distinct password levels:

Operation Passwords: Restrict access to specific buttons or screens, ensuring only authorized personnel can start or stop processes.

Upload/Download Passwords: Protect the project file itself, preventing unauthorized copying or modification of the program from the HMI.

System Settings Passwords: Protect local hardware configurations like IP addresses, brightness, and calibration. How to Change or Reset Your MCGS Password

If you have access to the original project files and the MCGS Studio software, the process is straightforward: 1. Modifying via Software Open your project in the MCGS configuration environment.

Navigate to User Administration (often under the System folder or "General Setup"). Step B: Secure Your Elements (Buttons & I/O)

Define different user levels (Level 1 to 9) and assign specific passwords to each.

Re-download the project to the HMI to apply the new security settings. 2. Resetting a Forgotten Password

If you are locked out of the system and do not have the original project, your options are more limited due to security protocols:

Factory Reset: Most panels can be restored to their factory state, which clears all passwords but also erases the project data. This typically involves a "tap-tap" procedure during boot-up or toggling physical DIP switches on the back of the unit.

Manufacturer Support: If the "factory password" (40721) does not work, you may need to contact the HMI vendor or the original system integrator who programmed the machine.

USB Workaround: 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

This content covers the standard "System Password," the specific "Download/Upload Passwords," and how to handle lost password scenarios.

Step B: Secure Your Elements (Buttons & I/O)

This is the most important step. You must restrict individual HMI components:

  1. Double-click a button (e.g., "Change Motor Speed").
  2. Go to the Security tab (or Property setting).
  3. Check Enable Security.
  4. Set Minimum Operation Permission Level to 10.

4. Forgotten Runtime Password for Project Opening

If you protected your .mcgs project with a password and forgot it, no software backdoor exists. You would need to restore from backup or contact MCGS support with proof of ownership.

Part 5: Persistent Passwords – Saving to EEPROM or Recipe

A hardcoded Master_PW = 1234 is erased when you recompile the project. How do you make password changes permanent? Here is how MCGS HMI password work with data persistence:
