DeviceNet is a digital, multi-drop network and a producer-consumer network. The digital, multi-drop network connects and serves as a communication network between industrial controllers and I/O devices and each device and/or controller is a node on the network. As the producer-consumer network, DeviceNet supports multiple communication hierarchies and message prioritization. These systems can be configured to operate in a master-slave or a distributed control architecture using peer-to-peer communication, offering a single point of connection for configuration and control by supporting both I/O and explicit messaging. Another unique feature is having power on the network.
