• Fieldbus: CANopen

• 8 digital channels, configurable as inputs or outputs

• Auto-configuration of I/O modules

• Convenient I/O configuration with Automation Studio V4.3 and later

• 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)

• 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)

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 synchronous, event and polling are supported as well as PDO linking, life/node guarding, heartbeat, emergency objects and much more.

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).

Automation Studio can be downloaded at no cost from the B&R website ( www.br-automation.com ). The evaluation license is permitted to be used to create complete configurations for fieldbus bus controllers at no cost.
