Why use CANbus in commercial vehicles, mobile plant or industrial machinery?
Integrating electronic controls in vehicles and machinery gives savings on cabling, construction and building. And it’s all brought together by one of the most widely successful control system standards ever: CANbus. Developed originally (by Bosch) with automotive applications in mind, CANbus is now an international standard (ISO 11898), which is why it’s the most sensible (and widely-used) approach to developing such a control system. A single pair of wires is sufficient as the transmission medium (making wiring very easy), and because CANbus is now used in such huge volumes, all the components are extremely affordable. Its high transfer rate and high transmitter reliability, as well as the ability to recognise data error, makes it ideal in electrical noisy environments, where earthing/grounding can be a problem. For more in-depth background, or to see just how widely CANbus is used, you’ll find several user groups on the internet as well as tremendous resources such as CIA, the CAN i
