1.3 Data exchange in the DeviceNet
DeviceNet has been developed by Rockwell Automation and the ODVA (Open DeviceNet
Vendor Association) as an open field bus standard, based on the CAN protocol. DeviceNet
belongs to the CIP-based networks. CIP (Common Industrial Protocol) forms the user
interface of DeviceNet and defines the exchange of:
explicit messages with low priority, e.g. for configuration or diagnosis
I/O messages, e.g. time-critical processing data.
Note
The Open DeviceNet Vendor Association (ODVA) is the user
organisation for DeviceNet. Publications on the DeviceNet/
CIP specification can be found under:
