Can-Network (Controller Area Network): Overview

CAN (Controller Area Network) is a standardised system for multiplex-communication. Volvo has developed a new standard for multiplex communication - VOLCANO. VOLCANO is a further development of CAN and operates with real time operation and prioritising. The description of prioritising is developed from VOLCANO but is designated CAN.

The standard for Control area network (CAN) specifies:

• That two cables should be used (CAN H and CAN L)
• Which voltage levels should be used
• What a message should look like
• How transfer errors should be handled.
