Initial addresses of load/unload locations:
Loading/unloading location
Example calculation of address DBW n+24 (magazine no. target)
n = (m–1) * len + 4
m =2 ; len = 30
Address for magazine no. target of 2nd load point is DBW 58.
Loading point 1 is intended for loading/unloading in (all) spindles/tool holders.
This must be considered when assigning the loading interface
(applies with ShopTurn on NCU (HMI embedded); with PCU 50.3 this is consid-
ered automatically). Loading point 1 is also used to relocate/position tools in any
location (e.g. buffer location).

1: n = 4
2: n = 34
3: n = 64
4: n = 94
m = location no. of load location
len = 30 (length of one load location)
n = (2–1) * 30 + 4 ==> n = 34
DBW (34 + 24) = DBW 58
