2.1 DeviceNet
DeviceNet was developed by Rockwell Automation and ODVA (Open
DeviceNet Vendors Association) as an open field bus standard based on the
CAN protocol.
DeviceNet is an object-oriented bus system and works using a producer/
consumer model.
DeviceNet‘s application layer uses the CIP protocol (Common Industrial
Protocol). CIP defines the transfer of I/O data in real time via I/O messages
(I/O messaging or implicit messaging), as well as the transfer of request and
response data for configuration, diagnostic, and management purposes
(explicit messaging). CIP is an object-oriented protocol and is typically used
to network sensors, variable frequency drives, and actuators with higher-
level automation devices (PLCs).
DeviceNet devices within a DeviceNet network can function as a client
(master), server (slave), or both.
DeviceNet networks can support a maximum of 64 bus nodes.
Baud rates of 125, 250, or 500 kBaud can be achieved (depending on the
type of cable used).
