Bus controllers for CANopen and Powerlink

Bus controllers for CANopen and Powerlink

CANopen has become one of the leading I/O profile standards in the automation industry. Originally designed solely for CAN, it can now also be found in other forms. Particularly in combination with Powerlink, it expands into the high-performance realm with real-time Ethernet. Now new bus controllers have been introduced for both CAN and Powerlink to round off the existing range of products.


The CAN bus controller meets the CANopen specifications DS 301 and DS 401. Automatic baud rate detection, PDO linking, life/node guarding, emergency objects and many more features are supported. The integrated X2X Link connection makes it possible to connect additional modules. AutoMapping is used to automatically detect these modules, whose data is then placed in the I/O map. The 16 digital channels can be configured to operate as digital inputs or outputs, which are then individually directed to M8 connections.


The Powerlink bus controller has two M12 connections for the fieldbus to allow easy network wiring. An additional M12 serves as the connection for expansion modules. 16 additional digital channels are also provided here, which can each be configured to operate as input or output. Depending on the design, these are directed individually to M8 or in pairs to M12 connections.


Both systems provide the user considerable cost savings by offering an integrated T-connector / integrated hub. The integrated connection for local expansion makes it possible to connect any system component from the B&R series X20, X67 and XV.
