CAN stands for Control Area Network and is a
single serial bus system in which all network devices are equal, or
peer to each other. This means each control unit can send and
receive signals independently. In contrast to the other protocols,
CAN does not address the device, but rather the message used by the
device to decide whether or not the data is required. Each control
unit on the CAN bus is equal to the other, so that important data
can take precedence over unimportant data. The essential features of
CAN bus are a high data transfer speed of 10 Kbps to 1Mbps. As a
field bus, the CAN bus is used for networking complex controllers.
An important
field of application for the CAN bus is the automotive industry. Due
to high demands
e.g. for protection against electromagnetic disturbances, real-time
capability for fast procedures and high reliability, a two-wire bus should
replace the extensive cable trees used to connect electrical systems. The
CAN bus also finds application in industrial control systems and automation
technology (such as programmable control systems, handling devices,
robotics, medical equipment, building control systems).
