This report addresses the password protection mechanisms used in MCGS (Monitor and Control Generated System) HMI panels (e.g., TPC series). The investigation covers default engineering passwords, runtime system access passwords, and password recovery methods.
Key finding: Many MCGS devices lack brute-force protection, and default/backdoor passwords pose a significant security risk if not changed.
Introduction: The Silent Guardian of Your Automation System
In the world of industrial automation, the Human-Machine Interface (HMI) is the window into your programmable logic controller (PLC) and machinery. For users of MCGS (Microcomputer Control Group System) — widely known as Kinco in Western markets — the password is the first line of defense against unauthorized tampering.
But what happens when you forget the password? Or when a legacy machine arrives without documentation? Or when you need to implement a complex, multi-level user hierarchy? Understanding the MCGS HMI password system is not just about security; it’s about operational continuity.
This article covers everything: default factory passwords, step-by-step recovery methods, password bypass procedures, and best practices for setting up user groups.
For high-security applications, consider using external PLC user management or Windows CE embedded security (on advanced MCGS units).
If you need a step-by-step tutorial for a specific MCGS model (e.g., TPC7062Ti, TPC1570Gi) or a sample project file, let me know.
You're looking for a detailed feature overview of the MCGS HMI (Human-Machine Interface) password protection feature.
MCGS HMI Overview
MCGS (Monitor Control and Graphical Software) is a popular HMI software used for monitoring and controlling industrial automation systems. It provides a graphical interface for operators to interact with the system, view data, and perform control actions.
Password Protection Feature
The password protection feature in MCGS HMI is designed to restrict unauthorized access to the system, ensuring that only authorized personnel can view or modify sensitive data, configure the system, or perform critical control actions.
Detailed Feature Overview
Here are the key aspects of the password protection feature in MCGS HMI:
Benefits
The password protection feature in MCGS HMI provides several benefits, including:
Configuring the MCGS HMI (Human-Machine Interface) password is a critical step for securing industrial control systems, preventing unauthorized adjustments to machine parameters, and protecting intellectual property within the HMI application. Default & Factory Passwords
If you are accessing a new or reset unit, use these common default credentials:
Factory Password: 40721 is often used for factory-level resets or initial setups.
General Settings Default: Many MCGS and related HMI systems utilize 111111 or m1111111 as the initial password for local settings.
Communication Bridge: If using a network bridge (like NET30-MPI), the default login is often admin with no password initially set. Password Protection Levels
MCGS software allows for granular security across different operational "classes" or levels:
User Levels: You can configure up to 16 user levels. Higher levels (e.g., Level 16) inherit the privileges of all lower levels.
Component Restriction: Individual buttons, input fields, or screens can be locked so only users with a specific security level can interact with them.
IoT & Remote Access: Specific passwords can be set for VNC (Virtual Network Computing) to allow secure remote monitoring via PC or mobile apps. How to Configure Passwords in MCGS Software What is the default password in the HMIs local settings?
MCGS HMIs come with factory-set passwords for initial configuration and system access. System Settings Default: 111111 or m1111111.
Factory Programming Reset: 40721 (often used during initial software burning or language changes). mcgs hmi password
Common Industry Defaults: Some units may use generic codes like 2222 or user-defined defaults like maint if previously modified by a technician. 2. Password Protected Areas
Passwords in MCGS are typically applied to three distinct levels:
Local System Settings: Accessing the HMI's internal configuration (VNC, network settings, and project upload/download) often requires a password.
Project Security: Developers can lock projects to prevent unauthorized modification, decompiling, or uploading from the HMI.
Runtime User Access: Specific screens or buttons can be locked behind user login prompts, requiring unique usernames and passwords managed via a local database. 3. Password Reset and Recovery
If a password is forgotten, several methods exist to regain access, though most will result in the loss of current project data. How to reset a password of CP600 HMI
Managing passwords on an MCGS HMI (Kunlun Tongtai) involves several distinct security layers, ranging from factory-level access to project-specific user permissions. Because these devices are frequently used in industrial automation, security is tiered to prevent unauthorized machine operation or project modifications. Common Default & Factory Passwords
If you are locked out of system-level settings or performing a factory reset, these standard codes are often used:
Factory Access Code: 40721 is a documented factory password used during system resets or language changes.
Common Industry Defaults: If the factory code does not work, common fallback passwords for industrial panels include 111111, 123456, or leaving the password field blank. Password Protection Types
In the MCGS configuration software (MCGS embedded version), there are typically three types of password protection:
Project Upload/Download Password: Protects the compiled project file. Without this, you cannot "read back" the program from the HMI to a PC or overwrite it with a new one.
Screen/User Access Passwords: Set within the HMI application itself. Designers use these to restrict specific buttons, navigation to sensitive screens (like "Settings" or "Calibration"), or modification of PLC parameters.
VNC/Remote Monitoring Password: Required if you are accessing the HMI via a network using a VNC viewer or the MCGS Debugging Assistant. How to Reset or Manage Passwords In MCGS Embedded or MCGS Pro : If
If a password has been forgotten, the recovery path depends on the level of protection: Troubleshooting Password Protection on Chinese MCGS HMI
It looks like you're asking about password issues or mechanisms for an MCGS (Monitor and Control Generated System) HMI.
Here’s a concise breakdown of common topics related to MCGS HMI passwords:
MCGS HMI panels are widely used in industrial automation but frequently deployed with default passwords unchanged. This creates a critical vulnerability. Organizations must enforce password policy, restrict physical access, and consider upgrading to newer models with improved security, such as login lockout and password complexity.

In the dusty corner of a busy textile factory, a "cost-effective" MCGS HMI panel governed the massive weaving machines
. For years, it chirped along reliably, its bright screen displaying data in a language only the senior technician, Mr. Chen, could fully interpret. But when Mr. Chen retired, he took a vital piece of knowledge with him: the system password The Locked Gate
One Monday morning, the line ground to a halt. A minor calibration was needed, but when the new lead engineer, Elias, tapped the screen, he was met with a stark, immovable password prompt. He tried the usual suspects:
, and even the factory’s founding date. Nothing. The HMI, built by a Chinese firm specializing in affordability, seemed to have its own digital stubbornness. The Software Struggle Elias spent the night scouring forums. He found the MCGS Embedded V7.7
software, which promised "stronger security features". But there was a catch: the software was designed for a Chinese version of Windows. When Elias tried to install it on his North American laptop, the characters turned into unreadable "mojibake" (scrambled text). He felt like he was trying to solve a puzzle where the pieces were written in invisible ink. The Secret in the Script
Desperate, Elias remembered an old forum post about "cracking" MCGS passwords. He didn't want to break the machine, just talk to it. He realized that the password wasn't just a gate—it was likely stored deep in the PLC properties or the application's configuration file.
He eventually found a workaround using a virtual machine running a specific language environment. After hours of tinkering, he bypassed the screen and discovered the "secret" password Mr. Chen had set: —the very default suggested by some older manuals. The Lesson Learned
The factory roared back to life. Elias didn't just reset the password; he added a physical key-switch
next to the HMI. Now, anyone with the authorized physical key could access the settings, ensuring that even if a password was forgotten, the machines would never have to stop again. default passwords for specific HMI brands or how to set up role-based security to prevent this in the future?
