Example:
A custom function is defined to change the logic state of parallel port
output pins Dout(3) and Dout(4) to indicate four ranges of
displacement of the channel 1 probe. The value ranges of C1 and the
corresponding logic states of Dout(3) and Dout(4) are shown in this
truth table.
This custom function is defined in a hidden dimension and uses 2
parameters to set the logic states of Dout(3) and Dout(4).
H1 = DefFn1(Dout(4,Param1),Dout(3,Param2))
Later, the function is called in a Case operation and the 2 parameters
are passed in the calling statement that correspond to the logic states
of Dout(3) and Dout(4) shown in the truth table above.
H2 = Case((C1<0mm),Fn1(0,0),
((C1>=0mm)&&(C1<0.5mm)),Fn1(0,1),
((C1>=0.5mm)&&(C1<1.0mm)),Fn1(1,0),
((C1>=1.0mm)&&(C1<1.5mm)),Fn1(1,1))
C1 value range Dout(4) Dout(3)
<0 mm 0 0
>=0 mm AND <0.5 mm 0 1
>=0.5 mm AND <1.0 mm 1 0
>=1.0 mm AND <1.5 mm 1 1
