3.3.2 LIN Signal
LIN Signal
function blocks are used to specify input and output signals on the LIN bus. There
are
130
LIN Signal
function blocks available to the user. Each
LIN Signal
function block has
one signal input and one signal output for interfacing with other function blocks.
Figure 7. LIN Signal Function Block
Configuration parameters of the
LIN Signal
function block are presented below:

–
Type of the LIN signal.
Input Signal
Source
Not
Connected
Any signal output of any
function block or “Not

signal is output (data is
sent on the LIN bus).
Output Signal
Autoreset Time
