Presentation
Schneider Electric has selected the CANopen bus for its machines and installations
because of its wealth of functions and its resulting benefits in the automation world.
This decision was based on the general acceptance of CANopen by the automation
engineer community due to its openness and universality, and the fact that CANopen
products are increasingly used in control system architectures.
CANopen is an open communication bus supported by more than 400 companies
worldwide, and promoted by CAN in Automation (CIA) http://www.can-cia.org/.
CANopen conforms to standards EN 50325-4 and ISO 15745-2.
CANopen brings transparency to Ethernet
The CANopen bus is a multi-master bus ensuring reliable, deterministic access to
real-time data in control system equipment. The CSMA/CA protocol is based on
broadcast exchanges, sent cyclically or on an event, to ensure optimum use of the
bandwidth. A message handling channel can also be used to define slave
parameters.
The bus uses a double shielded twisted pair on which, with the Altivar IMC drive
controller type S, Modicon M238 logic controller type S, Modicon M258 logic
controller type S, a maximum of 16 slave devices are connected by daisy-chaining or
by tap junctions. The variable data rate between 20 kbps and 1 Mbps depends on
the length of the bus (between 20 m and 1000 m).
Each end of the bus must be fitted with a line terminator.
The CANopen bus is a set of profiles on CAN systems, possessing the following
characteristics:
bbOpen bus system
bbData exchanges in real time without overloading the protocol
bbModular design allowing modification of size
bbInterconnection and interchangeability of devices
bbStandardized network configuration
bbAccess to all device parameters
bbSynchronization and circulation of data from cyclic and/or event-controlled
processes (short system response time)
