Protection levels for system frames

The machine manufacturer or user can assign the appropriate

protection levels for system frames as well as for individual functions

and data areas using display machine data.

These machine data are assigned protection level 7 by default during

the standard commissioning procedure. This means that access is

granted to all these data areas and functions when the keylock switch

is in the 0 position.

If required, these protection levels can be changed by the machine

manufacturer or user. Protection levels 0 to 3 can also be entered.
