Mcgs Hmi Password Work (EXTENDED ⇒)

MCGS does not use single "Admin" or "User" accounts by default. Instead, it operates on a numeric system:

: When an operator presses a restricted button, a login script calls the standard MCGS logon dialog box. The system verifies the input against an encrypted local database stored in the HMI flash memory. 3. Step-by-Step: Implementing Security in MCGS Pro

The standard logic flow is as follows:

Keep un-passworded master source files ( .mce / .mpc ) on a secure, air-gapped backup server. Only password-protect the runtime versions deployed to the factory floor.

You may need to use the "File System Clear" tool in the system menu to wipe the HMI, which will delete the project entirely, requiring a fresh download. MCGS does not use single "Admin" or "User"

Securing these systems is critical for keeping industrial processes safe. MCGS HMIs use a multi-tiered password system to protect intellectual property, prevent unauthorized parameter changes, and control equipment access.

Do you have the installed, or are you trying to recover a password from a locked HMI screen ?

To get MCGS (Monitor and Control Generated System) HMI passwords to work, you generally need to address three areas: the default credentials for initial access, the user authority settings within the MCGS software, and the recovery of forgotten passwords.

Always document the passwords used for user levels 1, 2, and 3.

If the engineering source file password is lost, or if you are trying to upload a project from an HMI that is password-protected, you hit a strict security wall.
