MCGS (Monitor and Control Generated System) HMIs use a hierarchical password and security system to manage user permissions and protect system integrity. Access is typically divided between system-level settings project-specific user management 1. System-Level Passwords

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

This is the most important step. You must restrict individual HMI components: mcgs hmi password work

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.

C. Download/Upload Password

• Purpose: Prevents unauthorized firmware updates or project downloads into the HMI.
• Function: If set, you cannot download a new project to the HMI hardware or upload the existing project from the HMI to a PC without providing this credential.

or default system password is used during initial setup or after a factory reset to regain control Default & System Passwords Factory Default Password

• Note: MCGS typically has a default "Logout" time (e.g., 5 minutes of inactivity).

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.

How it works: Every interactive component (button, input box, slider) has a property called "Minimum Operation Permission Level" . If the currently logged-in user’s level is less than the component’s required level, the component is grayed out or completely invisible.
