REFSCALE—Range Scaler
The REFSCALE function block scales INPUT within the input range specified by IN_MIN
and IN_MAX to one of the output ranges specified by OUT_MIN_1 and OUT_MAX_1 or
OUT_MIN_2 and OUT_MAX_2.
When OUT_MIN_2 and OUT_MAX_2 are both set to zero, OUT_MIN_1 and OUT_MAX_1
is considered as the active output range. If either OUT_MIN_2 or OUT_MAX_2 has a
non-zero value, then OUT_MIN_2 and OUT_MAX_2 will be considered as the active
output range.
The output range can be flipped over the horizontal axis using by setting INV to TRUE.
