Note
S It may be useful to perform a data saving operation in which only altered
machine data are saved prior to upgrading software in cases where the
defaults in the new software are not the same as those in the earlier
version. This applies particularly to machine data which are assigned
SIEMENS protection level 0.
Recommendation
MD 11210 UPLOAD_MD_CHANGES_ONLY should be set to “1” or the corres-
ponding bits set to “1”. With this setting, the transferred files contain only those
data which deviate from the default. This is advantageous for future software
upgrades.
Continue from “Standard system start-up” or “Archiving by area”.
