Password protection
You can protect the "Logon/Settings" menu from unauthorized access by assigning a
password.
This prevents inadvertent wrong operation and increases security for the plant or machine
security because access to the settings is denied. If the user does not enter a password, this
user can only access the "Contrast", "Device Info" and "Version Info" menu commands.
When a password is assigned, the following dialog appears when the user attempts to open
the "Logon/Settings" menu:
Password
|
Figure 6-3 Password dialog
You need to enter the password again to access the "Logon/Settings" menu after you closed
the previous session.
NOTICE
Password no longer available
If the Loader password is no longer available, you can only call the "Logon/Settings" menu
again after you update the operating system.
All data on the HMI device will be overwritten when you update the operating system.
Note
The currently active entry is always indicated in a dialog.
