7.3 Data backup using machine data
Backing-up modified values
When backing-up machine and setting data, the general machine data
MD11210 $MN_UPLOAD_MD_CHANGES_ONLY (only modified MD data are backed-up)
can be used to define whether all data are output or only data that deviate from the default
setting.
If a value of a data item that is stored as an array is changed, the entire MD array is always
output (e.g MD10000 $MN_AXCONF_MA-CHAX_NAME_TAB).

UPLOAD_MD_CHANGES_ONLY
MD backup of changed MD only
Min. input limit: 0
Protection level: 2/4
Selection of differential MD upload:
Bit 0 (LSB) Scope of the differential upload with TEA files (area-by-area archiving)
0: All data are output
•
1: Only machine data are output that deviate from the standard (this does not apply to
•
INITIAL_INI)
If a value is changed for a piece of data that is saved as array, then the complete MD array
is always output
(e.g. MD10000 $MN_AXCONF_MACHAX_NAME_TAB).
Bit 1 Scope of the differential upload with INI files
0: All data are output
•
1: Only data that deviate from the standard are output
•
(e.g. INITIAL_INI)
Bit 2 Change to an array element
0: Complete array is output
•
1: Only modified array elements are output
•
Bit 3 R parameters (only for INITIAL_INI)
0: All R parameters are output
•
1: Only R parameters not equal to zero are output.
Bit 4 Frames (only for INITIAL_INI)
0: All frames are output.
•
1: Only frames not equal to zero are output
•
Bit 5 Tool data, cutting edge parameters (only for INITIAL_INI)
0: All tool data are output
•
1: Only tool data not equal to zero are output
•
Bit 6 Retentive system variables
($AC_MARKER [ ]; $AC_PARAM [ ] only for INITIAL_INI)
0: All system variables are output
•
1: Only system variables not equal to 0 are output
