: MCGS 8.0 and later employ AES-256 encryption for password storage, making database recovery impractical. For these versions, the official clearance process is the only viable approach.
MCGS includes two fixed, unmodifiable entities:
MCGS HMI的密码体系不仅能有效，还能实现 精细化的权限管控 。从最基础的 用户/用户组配置 ，到运行时的 !LogOn() 登录函数 ，再到 动态密码脚本 与 USB密钥登录 等高级功能，它为工业现场的安全生产提供了可靠屏障。合理运用这套机制，能显著提升生产线的安全性，避免因参数误改造成重大经济损失。
在登录按钮的"按下脚本"中输入判断逻辑，当系统检测到登录成功和所属权限后，自动跳转到对应页面。 mcgs hmi password work
Use MCGS scripts to automatically log users out after a few minutes of inactivity to prevent unauthorized access to an unattended screen.
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.
Assign a , a Password (alphanumeric depends on your HMI model support), and an Authority Level (e.g., Operators = Level 1, Engineers = Level 5, Admin = Level 9). Step 3: Applying Passwords to HMI Elements To restrict a specific button, data input, or screen: : MCGS 8
When downloaded to the physical HMI, this button will remain locked until the correct password elevates the session privilege. Project Upload/Download Protection
This granular approach ensures that operators see only the controls appropriate to their role, while sensitive configuration options remain accessible only to authorized personnel.
MCGS operates on a user-level and security-group-level permission matrix. Instead of applying a single password to the entire screen, the software restricts access based on the authority of the logged-in user. User Levels and Permissions In the world of industrial automation, security is
Are you configuring or trying to recover a locked project file ?
: Some HMIs allow you to extract the project or log files directly to an external drive, which can sometimes be analyzed to find stored credentials.
Note: These are defaults and may not work if the user has changed them. 3. How to Reset/Bypass Forgotten MCGS HMI Passwords
