B&R X20cBC0043-10 Bus controller CANopen slave

General information

Controller Area Network (CAN) is widespread in automation technology. CAN topology is based on a line structure

and uses twisted wire pairs for data transfer. CANopen is a higher-layer protocol based on CAN. The standardized

protocol offers very flexible configuration options.

This bus controller makes it possible to connect up to 253 X2X Link I/O modules to CANopen. A transition between

IP20 and IP67 protection is possible by directly connecting X20. X67 or XV modules to one another at distances of

up to 100 m each across control cabinet boundaries as required. All CANopen operating modes such as synchro

nous, event and polling are supported as well as PDO linking, life/node guarding, heartbeat, emergency objects

and much more.

• Fieldbus: CANopen

• Auto-configuration of I/O modules

• I/O configuration via the fieldbus

• Constant response times even with large amounts of data (max. 32 Rx and 32 Tx PDOs)

• Configurable I/O cycle (0.5 to 4 ms)

• Configurable transfer rate or automatic transfer rate detection

• Heartbeat consumer and producer

• Emergency producer

• 2x SDO server, NMT slave

• Simple bootup (autostart)

• Terminal access via serial interface on the X20PS9400

• Integrated terminating resistor

Information:

With multifunction modules, the bus controller supports only the default function model in the event

of automatic configuration by the bus controller (see the respective module description).

Automation Studio V4.3 or later can be used to easily create configuration files (e.g. DCF files). All

other function models are also supported by transferring configuration data to the bus controller (e.g.

via the master environment with an SDO download).

The evaluation license is permitted to be used to create complete configurations for fieldbus bus con

trollers at no cost.

Coated modules

Coated modules are X20 modules with a protective coating for the electronics component.

This coating protects X20c modules from condensation and corrosive gases.

The modules' electronics are fully compatible with the corresponding X20 modules.

For simplification purposes, only images and module IDs of uncoated modules are used in this data

sheet.

The coating has been certified according to the following standards:

• Condensation: BMW GS 95011-4. 2x 1 cycle

• Corrosive gas: EN 60068-2-60. method 4. exposure 21 days
