Restrict access to settings on the HMI device

By default, any user not logged into the project on the HMI device has Administrator access to the Settings screens. These screens in the
Predefined Screens
 folder of the
Project Explorer
configure the HMI device at runtime. Limit the access guest users have to the Settings screens by assigning any role but the
Administrator
 role. Users who are not assigned the Administrator have Read Only access to the Settings screens. This prevents non-Administrator users from disrupting the system. For example, a Guest user cannot reboot the HMI device. The user can still navigate to and open all of the Settings screens on the HMI device to review the HMI device settings and configuration.
To restrict access settings on the HMI device
  1. Select
    Tools > Security Administration
    . The
    Security Administration
     dialog box opens.
  2. In the
    Guest User
    box after
    Role
    , select any role, including
    None
    , that is not the
    Administrator
    role.
    All options on the Settings screens on the HMI device are Read Only for any user except an administrator.
