1.4 Product Overview

This programming guide relates to the CANopen interface.
®
frequency
CANopen is a low-level network that standardizes
communications between industrial devices (sensors, limit
switches, motor controls) and high-level devices
(controllers). CANopen follows the open systems intercon-
nection (OSI) model and is based on CAN technology for
media access control and physical signaling.
Configure CANopen systems to operate in a master/slave
or a distributed control architecture using peer-to-peer
communication. Up to 127 nodes in a multi-drop network
topology are supported. Nodes can be removed or
inserted without powering down the network.
Each node on the network has its own unique node ID to
distinguish it on the network. The access control is based
on the carrier sense multiple access/collision avoidance
(CSMA/CA) principle, meaning that all nodes may have
access to the network at the same time. When 2 nodes
attempt to get control of the network bus simultaneously,
the CAN protocol resolves the issue by arbitration. This
allows to avoid collisions on the network.
CANopen defines device profiles for devices belonging to
specific classes. For other devices, define a custom class to
make it CANopen compatible. All of the above enhances
the interchangeability and interoperability of the network.
