The world of HMI password management is often a mix of routine security and complex troubleshooting, especially for those working with equipment sourced from international markets. 1. The Gateway: Default Passwords
If you are trying to access system settings or a new project for the first time, try these common defaults: 888888 or 000000 (six zeros). System Settings Password: Often 111111 or 123456 . Engineer Mode: 666666 . Configuring Passwords in MCGS Embedded
Best practices and mitigations
MCGS does not simply use a "single password" for the entire system. Instead, it utilizes a hierarchy based on and Access Levels .
在用户管理器窗口下半部分的用户组列表中，点击 新增用户组 按钮。在弹出的对话框中，设定用户组名称（如"操作员组""技术员组"），并完成创建。
Immediately, when the initial MCGS logo or loading screen appears, tap rapidly or hold down the screen corner (usually top-left or top-right) to access the hidden "System Menu" or Windows CE desktop.
Keep offline backups of project source codes in secure, encrypted engineering repositories rather than relying on HMI extraction methods.
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
Modern industrial systems increasingly rely on remote monitoring and control capabilities. MCGS supports these features through two primary password-protected mechanisms.
MCGS has special address ranges: LW 10000 to LW 10099 are retentive (survive power cycles). Modify your logic:
