Function Blocks

3.2.51 FTG_ - Falling Edge Trigger

FTG_ function blocks provide a high (1) output for one
scan cycle each time input P transitions from a high (1)
input to a low (0) input.

3.2.52 GB_ - Gain & Bias
GB_ function blocks provide action, gain, and bias
adjustments to input signal A. Although this block can
provide signal scaling, it should not be used if needed as a
reference for a range pointer. The SCL function block
should be used when scaling is required for this purpose.
