2.2.5 Redefining Protection Levels for NC Data

Function
The user can change the priority of the protection levels. Only lower priority
protection levels can be assigned for machine data, whereas higher or lower
priority protection levels can be assigned for setting data.
Example:
%_N_SGUD_DEF
REDEF $MA_CTRLOUT_SEGMENT_NR APR 2 APW 2
REDEF $MA_ENC_SEGMENT_NR APR 2 APW 2
REDEF $SN_JOG_CONT_MODE_LEVELTRIGGRD APR 2 APW 2
M30
The file becomes active when the next _N_INITIAL_INI is read in. Different
protection levels are specified for writing (changing) and reading (part program or
PLC).
Example:
MD 10000 has protection level 2/7, i.e., protection level 2 is required for write
access (corresponding to password) and protection level 7 for read access. In
order to access the machine data area, key switch position 3 or higher is required.
Undoing the protection level change
In order to undo protection level changes, the original values have to be restored.
Example:
%_N_SGUD_DEF
REDEF $MA_CTRLOUT_SEGMENT_NR APR 7 APW 2
REDEF $MA_ENC_SEGMENT_NR APR 0 APW 0
REDEF $SN_JOG_CONT_MODE_LEVELTRIGGRD APR 7 APW 7
M30
Protection levels for NC commands
Certain NC commands can be linked to protection levels to restrict their execution
to authorized personnel only.
