CANopen machine bus
Originally used in the automotive industry, CAN is increasingly used in general
industry. Several fieldbuses based on CAN lower layers and components are
available. The CANopen machine bus conforms to the ISO 11898 international
standard, promoted by the CAN In Automation association, which consists of users
and manufacturers and offers an excellent assurance of open access and
interoperability due to its standardised devices and communication profiles.
The CANopen bus is a multimaster bus which ensures reliable deterministic access
to realtime data in control system devices. The CSMA/CA protocol is based on
broadcast exchanges, sent cyclically or on an event, which ensures optimum use of
the passband. A message handling channel can also be used to define slave
parameters.
The bus uses a double shielded twisted pair, on which 127 devices maximum are
connected by daisy chaining. The variable data rate between 20 Kbps and 1 Mbps
depends on the length of the bus (between 30 and 5000 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:
b Open bus system.
b Data exchanges in real-time without overloading the protocol.
b Modular design allowing modification of size.
b Interconnection and interchangeability of devices.
b Standardised configuration of networks.
b Access to all device parameters.
b Synchronisation and circulation of data from cyclic and/or event-controlled
processes (short system response time).
b Interoperability between numerous international manufacturers.
