3.2.90 SCL_ - Scaler
SCL_ function blocks provide a means to scale an analog
signal. It will re-range a signal by using the range pointer
to reference the function block with the original range.
When the range pointer (input R) is not configured, the
function block will not re-scale the input signal but will
pass it directly to the output. The purpose, under this
situation, would be to provide minimum and maximum
scale, preferred decimal point position, and units for
another block (e.g. operator display) to reference.

3.2.91 SEL_ - Signal Selector
SEL_ function blocks can provide a high or low signal
selection on the three input signals. Unused inputs will be
set equivalent to the lowest real value when configured as a
HI selector and to the highest real value when configured as
a LO selector.
