3.1 CANopen
3.1.1 General
CANopen is an open, non-proprietary network protocol. It consists of a profile family, based on a
communication profile and several device profiles. The CANopen communication profile is
standardized as CiA DS-301 (Application Layer and Communication Profile).
The CANopen device profile for I/O-modules has been published as CiA DS-401 (Device Profile for I/O-
Modules).
CANopen is based on the following standards:
„
ISO 11 898 (Physical and Data Link Layer)
„
Layers 1 and 2 of the ISO/OSI communication model
„
CiA DS-301 (Application Layer and Communication Profile) C ANopen communication profile
„
CiA DS-302 (Framework for Programmable CANopen Devices) CANopen Network Management
NMT
„
CiA DS-401 (Device Profile for I/O-modules)
„
CiA DS-406 (Device Profile for Encoders) CANopen device profile for counter modules
„
CiA DS-102 (CAN Physical Layer for Industrial Applications) General application in the field sector
(connectors and bit rates) on the basis of ISO 11898
