Protection level

To access the SINUMERIK* machines operated with a high protection level
(0-3) from DNC, you have to set the appropriate protection level for downloads
and uploads in DNC. For this purpose, you have to enter the protection level in
the MCF file. If this is configured, prior to the download/upload, the protection
level on the machine is fetched, possibly the appropriate password set, and
after the download/upload reset again.
Changing the protection level by DNC also acts on the SINUMERIK user
interface, i.e. the machine operator has all operating capabilities possible with
this protection level!
