For many embedded MCGS models, you can enter a "factory" password to reset user credentials. On the HMI login screen, try entering .
Example: Master_PW = RW0 Pros: You can backup/restore passwords. Cons: Slightly slower read/write.
The simplest and most common method uses the built-in function !LogOn() . This function opens a standard system dialog box where users can enter their username and password. Here’s how to link it:

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
If the steps above fail, the HMI might be heavily locked or the project might be corrupted. For many embedded MCGS models, you can enter
The version of the you are running (e.g., MCGS Pro, Embedded Edition)
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.
Store passwords in or user database .
MCGS provides standard script commands to manage users without custom code.
In the world of industrial automation, security is not an afterthought—it is a necessity. Whether you are controlling a packaging line, a water treatment facility, or a CNC machine, unauthorized access to your Human-Machine Interface (HMI) can lead to catastrophic downtime or safety hazards.
| Component | Configuration | |-----------|---------------| | | Screen ID 0, numeric entry for password, login button | | Main Menu | Screen ID 1, shows “Logged in as: Operator/Tech/Admin” | | Parameters Screen | Screen ID 2, visible only if Access_Level >= 2 | | User Admin Screen | Screen ID 3, visible only if Access_Level = 3 , allows changing RW0 (master admin pw) and RW1 (operator pw) | | Logout Button | On all screens, sets Access_Level = 0 , Login_Flag = 0 , jumps to Screen 0 | Cons: Slightly slower read/write
Each user account belongs to a group, and each group is assigned a unique numerical security level (e.g., Level 0 to Level 99). 2. Object-Level Security Inheritance
