Provided by util.lib.

This function block specifies, whether the input value is within a set range and which

The input values IN, HIGH and LOW are each of the type INT, while the outputs O, U

and IL are of the type BOOL.

If the upper limit HIGH is exceeded by IN, O becomes TRUE, and when IN is below

LOW, U becomes TRUE. IL is TRUE if IN lies between LOW and HIGH.
