ding data word but only into the loading line (DW 2 of the magazine table).
FB 139 "Data distributor" searches for an empty location suitable for the tool size. Up to soft-
ware version 5, this location is output in DB 146, DW 5 as a locator number and in DW 4 as a
data word number. The user can now transfer the data from the data words of the loading line
to the data words of the empty location found.
