Save and compile the project before downloading it to the physical HMI hardware. 3. Dynamic Password Management via Runtime Scripts
Hold the highest clearance. They can modify all variables, view system screens, and alter lower-level user credentials.
The implementation is surprisingly straightforward:
For a password to "work" on the screen, you must use the standard login dialog or link a "String Input" box to the system variable !UserPassword . Handling Forgotten Passwords If you are locked out of an MCGS project: mcgs hmi password work
often has no password unless set during the initial configuration. Password Management and Reset
If you set access control on Screen 3, but a user can still jump to it via a “Goto Screen 3” button on Screen 2 — you forgot to protect the , not just the screen. Fix: Add Login_Flag = 1 in the button’s “Enable” condition or hide the button using Visible property.
A password prompt can be triggered when a user attempts to start a motor or change a setpoint. Screen Access: Save and compile the project before downloading it
MCGS manages these runtime levels using built-in system variables and scripts.
Despite best efforts, password-related issues can still occur. Here are some common problems and their solutions:
This write-up explains how passwords function at the engineering level, the hierarchy of user levels, and the standard methodology for implementation. They can modify all variables, view system screens,
Check the system configuration properties for your input components. Ensure that the built-in keyboard driver is enabled for the project, or verify that the HMI operating system image fully supports the selected input language layout.
For engineers and technicians using —one of the most popular HMI brands in Asia and emerging global markets—understanding exactly how MCGS HMI password work is critical.
