CAN COMMUNICATION

CAN COMMUNICATION

System Description

NKS002BR

CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.

CAN Communication Unit

NKS002BS

Refer to 

LAN-40, "CAN Communication Unit"

  in “LAN SYSTEM”.
