4.1.1 Access levels
Protection levels
The SINUMERIK 802S provides a protection level concept for enabling data areas. The pro-
tection levels range from 0 to 7 whereby 0 is the highest and 7 the lowest level.
The control system comes with default passwords for protection levels 2 and 3. If necessary
these passwords can be changed by the appropriate authorized person.

5 User IS from PLC NCK
6 User IS from PLC NCK
7 User IS from PLC NCK
Protection levels 2 ... 3
The protection levels 2 and 3 require a password. The passwords can be changed after acti-
vation. For example, if the passwords are no longer known, the control system must be reini-
tialized (booting in Start-Up Switch position 1). This will reset all passwords to the default set-
tings for this software version.
If the password is deleted, protection level 4 is applicable.
The password remains set until it is reset using the Delete password softkey; POWER ON
will not reset the password.
Protection levels 4 ... 7
Protection level 4 is automatically set when no password is entered. If required, the protection
levels 4 ... 7 can be set from the user program via the user interface.
See Section 6.1.1 “Display Machine Data”.
Note
How to set the access levels is described in the User’s Guide “Operation and Programming”.
