CAN (Controller Area Network) systems are widespread in the field of 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. As a standardized protocol, it provides a high degree of flexibility for implementing a wide range of configurations.
The bus controller makes it possible to connect up to 253 X2X Link I/O modules 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 100m. 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.
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.
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.
