DeviceNet is a CAN based field bus which is used mainly in the automation engineering.
Number of nodes
Maximum 64 nodes per bus segment. Node addresses (0 to 63) can be set with DIP switches on the servo amplifiers.
Selectable are: 125 kBaud, 250 kBaud and 500 kBaud. Baud rates can be set with DIP switches on the servo amplifiers.
Common Industrial Protocol
DeviceNet uses the CAN specifications on the lower layers (1 to 4) of the OSI model with some additions. On the upper layers (5 to 7) DeviceNet uses the "Common of Industrial Protocol" (CIP) from the ODVA defined.
