About CAN

CAN (Controller Area Network)

The CAN protocol is an ISO standard (ISO 11898) for serial data communication. The protocol

was developed aiming at automotive applications. Today CAN has gained widespread use and

is used in industrial automation as well as in automotives and mobile machines.

 

There are a number of good reasons for why the CAN protocol is the right choice:

Mature standard

The CAN protocol has been around for more than 20 years (since 1986). There are now a lot of

CAN products and tools available on the open market.

Hardware implementation of the protocol

The CAN protocol is implemented in silicon. This makes it possible to combine the error

handling and fault confinement facilities of CAN with a high transmission speed. The method

used for distributing messages to the right receivers contributes to gaining a good use of the

available band width.Simple transmission medium. A common transmission medium is a twisted

pair of wires. A CAN system can also work with just one wire. In some applications different

kinds of links, optical links or radio links, are better suited. Though there is a transmission

hardware standard (twisted pair), it is not uncommon to use different transmission solutions

depending on system requirements.

 

Excellent error handling

The error handling of CAN is one of the really strong advantages of the protocol. The error
