DeviceNet is a network of low cost intelligent control that connects a wide range of intelligent devices such as sensors, valves, barcode readers, actuators, variable frequency drives, PCs, programmable logic controllers, etc.
DeviceNet allows industrial devices can be easily interconnected in a network and be managed remotely.
Being a. standard network, DeviceNet is ideal for applications that benefit from tight integration between devices.

DeviceNet Protocol Architecture
The Network
DeviceNet incorporates a network-based connection. A connection must be established initially for a UCMM (unconnected message manager) or an unrelated port group 2. From there, the explicit and implicit messages can be sent and received. Explicit messages are data packets that usually requires a response from another device. Typical messages are sensible collection of data settings or no-time. The implicit messages are data packets that are time critical and generally communicate real-time data over the network. Post an explicit connection must be used to set first before a connection is made implicit message. Once the connection is made, the identifier for the ABLE data routed to the corresponding node.
Example of a DeviceNet network
And Benefits
- Open standard ensures interoperability of various devices: interchangeability of similar devices from different manufacturers.
- Quick and easy installation resulting in a savings of time and space: it eliminates the standard electrical wiring.
- Ready for the future, for easy additions increased according to needs and changes.
- Reset time through improved intelligence into devices: DeviceNet alerts on network events allowing a faster drive.
- Efficient use of bandwidth through the media producer / consumer.
- Online configuration and additions without disconnecting the system.
