The Line Segment logic block provides linear scaling and biasing of an input value using one or more line segments where two points define a single line segment.

The Line Segment block reliability values are Reliable or Math Error. The Present Value retains its previous value on Math Error. The block remains reliable if the input is not reliable (ignores unreliability of the input).

You must open the Details view of this block to configure its Input Points and Output Points. See Configuring the Line Segment Block in the Configuring a System section.

The following table describes the inputs and outputs of the Line Segment logic block.
