FGEN Function Generator Function Block
Description
The FGEN label stands for Function Generator - 10 Segment.
This block is part of the
Auxiliary category.
Function
Generate output characteristic curve based on up to 11 configurable “Breakpoints” for both input (X) and
Output (OUT) values.
OUT = interpolation of OUT (Yb) values for segment in which X falls.
• If X <= X (1), then OUT = OUT (1)
• If X >= X (11), then OUT = OUT (11)
ATTENTION
The X(n) value must be < X(n+1) value. Thus, if fewer than 11 breakpoints are needed, be
sure to configure any unneeded breakpoints with the same X and OUT values used for the
previous breakpoint.
Input
X
= Analog Value
Output
OUT
= Calculated Analog Value
