CAN “Brotherhood” : SDS, DeviceNet and CAN Kingdom

DeviceNet, SDS and CAN Kingdom are all based on the ISO 11898 CAN communication protocol and circuits meeting the CAN specification. This implies that modules following any of the protocols can be connected to a very same CAN-bus. However, when modules following different protocols are connected to the same CAN bus, most often problems will arise due to conflicting interpretation of messages at the application level. CAN Kingdom differs from SDS and DeviceNet in one major principle way: CAN...

CAN Kingdom at Automotive

A modern automobile may have as many as 50 Controller-area networks (CAN) for various subsystems. Typically the biggest processor is the engine control unit, which is also referred to as “ECU” in the context of automobiles; others are used for transmission, airbags, antilock braking, cruise control, audio systems, windows, mirror adjustment, etc. Some of these form independent subsystems, but communications among others are essential. A subsystem may need to control actuators or receive...
