Password Protection for Standard/Special Screens
There is no password protection for standard/special screens. You can protect the
functions of the special screens bydoing the following:
• Prevent the output of the basic screen by branching to the standard/special
screens: To do so, use the configuration interface to specify an initial screen.
• Create your own process displays with the desired password level. Place the
selection of the special screens with the corresponding functions to the
softkeys.
5.10.1 Password Levels and Access Rights
You can assign a password level between 0 and 4 for each screen.

effect on the process sequence when displayed. As a rule, these are

To call screens of password level 0, a password is not required.
If you call a screen that is assigned a higher level than 0, you are
prompted on the display to enter a suitable password.
