The communication standard for CAN-based solutions |
CANopen in a higher layer protocol based on CAN (Controller Area Network),
which enables the communication between devices of different
manufacturers and guarantees an
interchangeability of devices.
The profile family CANopen defines a standardized application for distributed
industrial automation systems based on CAN. CANopen was developed within the
CAN-in-Automation (CiA)  international users' and manufacturers' group and is now
standardized as CENELEC EN 50325-4. Soon after its release, CANopen has found a
broad acceptance, especially in Europe where it can be considered the leading
standard for CAN based industrial and embedded system solutions.
The most important device types such as digital and analog I/O modules, drives, controllers,
programmable controls or encoders, are described by so called "Device Profiles". In these
device profiles functionality, parameters and the access to process data of standard
devices of the corresponding types are specified. Based on these standardized profiles
devices of different manufacturers can be accessed via the bus in exactly the same manner.
Vendor independence is thus achieved to a large extent as devices of different manufacturers
are interoperable and exchangeable.
By now it is used in many various fields, such as medical equipment, off-road
vehicles, maritime electronics, public transportation, building automation,
etc.

Nowadays CANopen is already implemented in varous devices and applications,
from catering coffee machines to maritime solutions. |
With the CANopenSolutions.com webpage we like to provide detailed information about the
CANopen protocol (see About CANopen), available products, like tools and CANopen protocol
stacks as well as CANopen literature and training.
