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.
Default:
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.
