Auxiliary function output for spindles

During program execution and after block search with "search via program test" (SERUPRO),
the pre-defined auxiliary functions S, M3, M4, M5, M19 and M70 are output channel-specific
on the NCU on which the spindle has been programmed and also axis-specific on the home
NCU.
Output of the channel-specific auxiliary functions
● DB21, ... DBW68 (extended address of the M function)
● DB21, ... DBD70 (M function 1)
● DB21, ... DBW98 (extended address of S function 1)
● DB21, ... DBD100 (S function 1)
Output of the axis-specific auxiliary functions
● DB31, ... DBD78 (F function for axis)
● DB31, ... DBW86 (M function for spindle)
● DB31, ... DBD88 (S function for spindle)
