What this chapter contains

This chapter contains a short description of the CANopen protocol
and the FCAN-01 CANopen adapter module.

CANopen protocol

CANopen is a higher layer protocol based on the CAN (Control
Area Network) serial bus system and the CAL (CAN Application
Layer). CANopen assumes that the hardware of the connected
device has a CAN transceiver and a CAN controller as specified in
ISO 11898.
The CANopen Communication Profile, CiA 301, includes both
cyclic and event driven communication, which makes it possible to
reduce the bus load to minimum while still maintaining extremely
short reaction times. High communication performance can be
achieved at relatively low baud rates, thus reducing EMC problems
and cable costs.
CANopen device profiles define both direct access to drive
parameter and time critical process data communication. The
adapter module fulfills CiA (CAN in Automation) specification CiA
402 (CANopen device profile for drives and motion control).
