4.5.12.1 General information
CAN (Controller Area Network) systems are widespread in the field of automation technology. CAN topology is
based on a line structure and uses twisted pair wires for data transfer. CANopen is a higher-layer protocol based
on CAN. This standardized protocol offers highly flexible configuration possibilities.
The bus controller makes it possible to connect up to 253 X2X Link I/O nodes to CANopen. A transition between
IP20 and IP67 protection outside of the control cabinet is possible by aligning X20, X67 or XV modules one after
the other as needed at distances up to 100 m. All CANopen transmission types such as synchronous, event and
polling modes are supported together with PDO linking, life/node guarding, emergency objects, and much more.
•
Fieldbus: CANopen
•
Auto-configuration of I/O modules
•
I/O configuration via the fieldbus (also supported by the B&R FieldbusDESIGNER)
•
Constant response times even with large amounts of data (max. 32 Rx and 32 Tx PDOs)
•
Configurable I/O cycle (0.5 - 4 ms)
•
Possible to configure the transfer rate or have it detected automatically
•
Heartbeat consumer and producer
•
Emergency producer
•
2x SDO server, NMT slave
•
Simple bootup (autostart)
•
Terminal access via the serial interface on the X20PS9400
Information:
Only the standard function model (see the respective module description) is supported when the bus
controller is used together with multi-function modules it has automatically configured itself.
The B&R FieldbusDESIGNER can be used to create configuration files (e.g. DCF files) in six easy steps.
All other function models are also supported by transferring configuration data to the bus controller
(e.g. from the master environment with an SDO download or via the serial interface).
The B&R FieldbusDESIGNER is available free of charge in the download section of the B&R website
