CAN is a message-oriented multi-master protocol for fast, serial data exchange and has established itself in numerous areas of industry where high robustness and data security, as well as low costs and a wide range of component suppliers, associated software, and tools, are essential. Examples include automotive engineering (networking of various control units, sensor units, and even multimedia units), automation technology (time-critical sensors in the field, monitoring systems), medical technology (magnetic resonance and computed tomography machines, laboratory equipment, etc.), as well as aerospace engineering (networking within avionics systems) and marine engineering. This multifaceted development is documented in the now fifth edition of this successful technical book by more than 40 competent professionals who address the topic.
