HEIDENHAIN CNC PILOT 4290 177
4.15.2 V Variables
The CNC PILOT uses value ranges to define the scope of variables::
■ Real V1 .. V199
■ Integer V200 .. V299
■ Reserved variables V300 .. V900
Requests and assignments:
■ Machine dimensions read/write (machine parameter 7)
Syntax: V{Mx[y]}
x = dimension: 1..9
y = coordinate: X,Y,Z,U,V,W,A,B or C
■ Interrogate external events
Is the bit value 0 or 1? The significance of the external event is
determined by the machine manufacturer.
Syntax: V{Ex[y]}
x = Slide 1..6
y = bit: 1..16
