Security for HMI devices

Access to the HMI device is either through user name and password or PIN.

Set up user accounts to access the HMI device on the

Security Administration

dialog box. Assign each user a password and/or PIN. Use the

Policies

tab on the

Security Administration

dialog box to create security policies such as password complexity and length and to enforce password strength.

Use the Guest user account to restrict users that do not log in. Have the Guest user view only the Home screen or certain screens.

The

HMI Device

screen in the

Predefined Screens

folder provides a way to prevent overwriting the runtime application in the HMI device. Clear

Allow Downloads

and

to prevent downloading a project or updating firmware on the HMI device.
