Protection against unauthorized use
You can protect the control panel against unauthorized access by using a password.
You can also protect the taskbar and the Desktop with the help of SecureMode. If the
HMI device is protected, "secure mode" is displayed on the Windows CE desktop.
You can find additional information on this in the section "
Setting up and disabling
SecureMode (Page
94)".
The "Transfer" and "Start" buttons can always be used without having to enter a password.
Password protection prevents maloperation. This increases the security of the system
or equipment because settings for the current project can only be changed after entering
the password.
NOTICE
Loss of data possible
If the password is no longer available, you can only cancel password protection by updating
the operating system. All data on the HMI device will be deleted when you update the
operating system.
Back up the HMI device's data.
Internet Explorer
Internet Explorer for Windows CE is installed on the HMI device.
