MD18112 $MN_MM_KIND_OF_SUMCORR, bit 4=1: Setup offsets are available
The sum offset is now composed of the "sum offset fine" (represented by $TC_SCPx) and the
setup offset (represented by $TC_ECPx). Two data sets therefore exist for one DL number. The
sum offset is calculated by adding the corresponding components ($TC_ECPx + $TC_SCPx).

The individual sets of sum offset parameters are differentiated according to the number ranges
of system variable $TC_SCP.

; Sum offset 2 is added to the D2 compensation instead of sum offset 1, i.e.
$TC_SCP23 to $TC_SCP31.
