If no screen touches are detected within a specified duration (e.g., 10 minutes), the script triggers the system function to log out the current user, resetting the access level to "Guest." 4. Troubleshooting Common MCGS Password Issues
MCGS (Kunlun Tongtai) Human-Machine Interfaces (HMIs) are widely used in industrial automation to monitor and control machinery. Securing these systems ensures that unauthorized personnel cannot alter critical machine parameters, cycle times, or calibration data. Implementing, managing, and troubleshooting password protections within the MCGS software environment requires a clear understanding of its security architecture. 1. How the MCGS Security Architecture Works
Prevents unauthorized users from pulling the compiled project file ( .mep or .vce ) off the HMI hardware and converting it back into editable source code.
The quickest solution is to reach out to the original machine manufacturer for the security code.
