Protection levels
The SINUMERIK 802C base line provides a protection level concept for
enabling data areas. The protection 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.

Protection levels 2 ... 3
The protection levels 2 and 3 require a password. The passwords can be
changed after activation. For example, if the passwords are no longer known,
the control system must be reinitialized (booting in Start–Up Switch position
1). This will reset all passwords to the default settings 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”.
How to set the access levels is described in the User’s Guide “Operation and
Programming”.
