Retention
The function block does not recognize retentive data.
Application example LS
An analog pressure sensor I1 in a tank delivers a value ranging from 0 (empty) to
10000 (full). When the cylindrical, upright tank is completely full, it holds 600 liters.
The purpose is for the current fill level to be converted to liters. The relationship
between the pressure and the fill level, and accordingly the volume as well, is linear,
meaning that an LS function block can be used.
The parameters would need to be configured as follows: X1=0, X2= 10000, Y1=0,
Y2=600
QV will then deliver the fill level in liters.
