DeviceNet protocol is the device-level, CAN-based manifestation of ODVA's Common Industrial Protocols (CIP) fieldbus suite. It is one of the most popular fieldbuses in the world today. Over 700 vendors support the DeviceNet standard worldwide.

DeviceNet utilizes the inherently robust CAN data and physical layers for data communication. In addition, DeviceNet takes advantage of the CAN power connection to supply operating voltage to devices with limited power requirements. The multi-drop bus structure of CAN simplifies wiring and minimizes cabling costs, as well as improving reliability by reducing the number of required connection points.

The DeviceNet protocol utilizes the producer-subscriber model for data interchange, allowing for multiple communication hierarchies to be implemented. Messages can be prioritized, and networks can be set up using master-slave or peer-to-peer models. Because it implements CIP, it interoperates seamlessly with other CIP-based protocols such as EtherNet/IP.

All DeviceNet devices are required to have a device description (EDS) file which loaded into the DeviceNet controller. The EDS file describes the device, its communication capabilities, and available data in a format that both the engineer and the controller can understand.
