Accessing or managing an MCGS (Kunlun Tongtai) HMI password depends on whether you are using a default factory setting or trying to recover a lost custom password. 1. Default Passwords
Allows user management, shifting schedules, clearing historical data logs, and calibrating the touchscreen hardware. 2. Setting Up User Security in MCGS Software
Maintain a secure, confidential log of passwords for your team.
For legacy MCGS models running older WinCE kernels, specific third-party software tools can extract the database files ( .dbf or system configuration files) from a USB backup.
In a standard industrial setup, users are categorized into roles: mcgs hmi password
In a typical industrial environment, an HMI acts as the command center for Programmable Logic Controllers (PLCs), sensors, and actuators. Without proper password protection, any operator could alter critical parameters, stop a production line, or cause equipment damage. MCGS Pro offers a robust security framework that includes runtime safety mechanisms and developer rights protection. Proper password configuration allows you to:
Check the box for and select the required user group from the dropdown menu. Save, compile, and download the updated project to the HMI. 4. How to Recover or Reset a Lost MCGS HMI Password
Most modern MCGS TPC units use standard Ethernet or a USB "B" port for programming. Older units may require a specific RS232 pinout (DB9).

If the HMI is in download mode or not restricted from uploads, you may be able to pull the project file and view or change the password settings within the software. Factory Reset: Accessing or managing an MCGS (Kunlun Tongtai) HMI
: Pops up a standard login dialog box demanding a username and password.
If you lose the engineering project password or the upload password, the compiled application cannot be natively reversed through normal software buttons.
Check the box to enable security and select the minimum user level or group required to operate that specific object. 4. How Operators Can Change Passwords at Runtime
Store your .mcgp project files and their associated passwords in an IT-controlled password manager (e.g., Bitwarden, KeePass) with your machinery documentation. In a standard industrial setup, users are categorized
Human-Machine Interfaces (HMIs) are the frontline of industrial automation, allowing operators to monitor and control complex machinery. Among the widely used systems in manufacturing and industrial automation is the MCGS (Monitor and Control Generated System) HMI, powered by MCGS Embedded Configuration Software.
Protects the internal system settings, network configuration, and firmware updates.
Use the hardware button (if available) or touch the screen to stop the project run. System Settings: Access the MCGS system settings menu.
