CANopen Basics Instruction Manual pdf - Kuhnke

Introduction
1.1 CANopen ® Features
There are many ways in which industrial automation
benefits from the serial data bus system:
� Standardisation
International standard (layer 1/2),
DIN ISO 11898 and DIN ISO 11519-1
� Manageability and ease of use
Simple configuration of new CAN networks and extension
of existing ones due to object-oriented information
exchange
� Speed
Max. transfer rate of 1 Mbit/s through a 40 m bus;
network extendable to up to 1000 m at reduced data
rates down to 50 kbaud; priority assignment to message
frames to ensure very short delays of a couple
of milliseconds only for the transfer of major messages.
� Cost-efficiency
Availability of low-cost logging and
transceiver modules as well as of microcontrollers
with their own CAN interface because this bus is
widely used in the automotive sector.
� Safety
Very safe data transfer even when EMC conditions
are tough.
