Input parameters

Output parameters

Description

This function block provides a linear interpolation of the input signal, using the

table passed as input (

Px_1

Px_9

and

Py_1

Py_9

). The parameter

N_SEG

specifies the number of the segments in which is divided the input range: if this

value is 0 or grater then 8, the output

AOUT

is always 0.0. Furthermore the FB

checks if the

input is out of range, and in this case it forces the minimum or the

maximum values provided for the output linearization.
