SMC_Interpolator
wM: WORD
If the interpolator passes an M object, i.e. a line describing an additional option, this output
will be set to the corresponding value and the program organisation unit will wait until it
is acknowledged by the bAcknM input.

Note!
The SMC_OUTQUEUE variable is empty at the end of an outline. If you want to
traverse the same outline again, you will either have to convert the CNC program
into an SMC_OUTQUEUE structure via the decoder and path preprocessing
POUs, or use the SMC_RESTOREQUEUE function. The latter is only possible if the
OUTQUEUE buffer is large enough to hold the entire outline.
