5.13 Controller Area Network (CAN)
5.13.1 Overview
5.13.2 Features
The Controller Area Network (CAN) is a serial communications protocol which is multi-master and
it efficiently supports distributed real-time control with very high level of security. Its domain of
application range from high speed networks to low cost multiplex wiring. In automotive
electronics, engine control units, sensors, anti-skid-systems, etc. are connected using CAN with
bit-rates up to 1Mbit/s.
In CAN systems, a node does not make use of any information about the system configuration
(station addresses). Any Nodes can be added to the CAN network without requiring any change
in the software or hardware of any node. The information on the bus is sent in fixed format
message of different but limited length. When the bus is free, any connected unit may start to
transmit a new message. The content of message is named by IDENTIFIER. The IDENTIFIER
does not indicate the destination of the message, but describes the meaning of the data, so that
all nodes in the network are able to decide by Message Filtering whether the data is to be acted
upon by them or not. Within a CAN network it is guaranteed that a message is simultaneously
accepted either by all nodes or by no node.
