DEFINITION
Limits an input Input 1 to the programmed maximum Max Val and
minimum Min Val values.
INPUTS
Input 1 — A signed integer that is limited.
Max Val — A signed integer that represents a maximum input value.
Min Val — A signed integer that represents a minimum input value.
OUTPUTS
Max Lim — High limit flag that is true when Input 1 > Max Val.
Min Lim — Low limit flag that is true when Input 1 < Min Val.
Output — A signed integer that results from limiting Input 1.
FUNCTION
1. If Input 1 < Min Val, then Output = Min Val and Min Lim is
true.
2. If Input 1 > Max Val, then Output = Max Val and Max Lim is
true.
3. If Input 1 < Max Val and > Min Val, then both are false and
Output = Input 1.
