MD number
Note
It might be sensible to back up only altered machine data before a software update if
changes have been made to the default machine data settings in the new software version.
This applies particularly to machine data that are assigned SIEMENS protection level 0.
Note
MD11210 $MN_UPLOAD_MD_CHANGES_ONLY should be set to "1" or the corresponding
bits set to "1". With this setting, the transferred files contain only those data, which deviate
from the default.
