Anybus CompactCom B40 Brick - CANopen

The Anybus CompactCom B40 for CANopen is a high-performance network interface in Brick format — ready-made with software and hardware to enable communication between your device and the CANopen network.


The B40 Brick gives you the flexibility to add your own connectors and network isolation. An alternative is to use the ready-made connector board from HMS. The B40 Brick is ideal for device manufacturers who are looking for a semi-integrated solution where connector flexibility, size and cost are key elements.


By implementing the B40 Brick into your product line, you can get connected to other B40 supported networks simply by switching to another Anybus Brick.


The B40 Brick enables fast communication between your device and CANopen. With its fast data transfer and very low latency, its the perfect match for even the most demanding industrial applications.


Features and benefits

  • A ready-made CANopen connectivity solution
  • Flexibility to add your own connectors and peripherals to limit size and costs
  • Easy mounting to your host PCB design
  • Short in-design with free assistance from HMS ensures a fast time to market
  • CiA pre-certified for network compliance (enables faster network certification)
  • Fast data transfer: Up to 512 bytes of process data in each direction,
    Up to 1524 bytes of acyclic data
  • Event-based interface method enables easy access to input and output data at any time
  • Fast, event-based application hardware interfaces: 8/16-bit parallel and highspeed SPI. I/O (shift register interface) is also available.
  • Solid security: Mandatory software signatures prevent unauthorized software to be downloaded to the module. Furthermore, encryption is used to prevent illicit copying.
