The Controller Area Network (CAN) was developed specifically for automotive applications in the early 1980s, and standardized as ISO 11898 in 1993. Due to its technical characteristics and the low cost of the bus interface, CAN today is used not only as a communication network for automotive electronic components, but also as an embedded network within systems in almost all areas of life. In addition, the CANopen and DeviceNet higher-layer protocols have been defined specifically for open automation solutions. These protocols use CAN as the base technology and provide additional specifications to allow device and plant configuration by system integrators and users.

CANopen is developed, standardized and maintained by CAN in Automation (CiA), and DeviceNet by ODVA.
