If you have the original project file but can't access the HMI, you can perform a factory reset. This typically involves using the MCGS ProSave or a similar utility to "Update OS" and "Reset to factory settings," which wipes all data and passwords from the device.

This security layer prevents unauthorized retrieval of the project compilation files from the physical HMI hardware back to a PC.

Draw three input boxes linking to local string variables: str_OldPwd , str_NewPwd , and str_ConfirmPwd . Create a "Submit" button. Write a script on the button action to validate the input:

Store all engineering, upload, and download passwords in an encrypted, centralized company database rather than relying on individual engineers' memory. mcgs hmi password work

IF str_NewPwd <> str_ConfirmPwd THEN !Message("New passwords do not match!"); ENDIF IF !SetUserPassword("Operator", str_OldPwd, str_NewPwd) = 1 THEN !Message("Password changed successfully!"); ELSE !Message("Invalid old password!"); ENDIF Use code with caution.

Restricts sensitive actions—like altering PID tuning parameters, clearing alarm histories, or entering manual calibration modes—to qualified personnel. 2. How the User Permission Architecture Works If you have the original project file but

Sensitive pages, such as "System Settings" or "Calibration," can be hidden behind a login screen. How Password Protection is Implemented

: To protect a specific button or input field, open its Properties , go to the security/enable tab, and set the minimum required Password Level (e.g., 1–16). 2. Project Upload & Download Security

This guide details the types of passwords available, how to configure them, and troubleshooting steps for recovery. Draw three input boxes linking to local string

Add a (text: "Enter Password"). Add a Numeric Input object linked to Entered_PW . Under its properties, set "Input Format" to decimal, "Max Length" = 4.

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.

Open the (in McgsPro: Project → Real-time Database). Create:
