Anybus CompactCom B40 Modbus Serial Interface - CANopen

The CompactCom B40 Modbus Serial for CANopen enable simple communication between your device and the CANopen network.

The CompactCom 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 CompactCom B40 Brick into your product line, you can get connected to other B40 supported networks simply by switching to another CompactCom B40 Brick.

The CompactCom B40 Brick enables communication between your device and CANopen. The CANopen network implementation is made directly into the CompactCom network processor — the award-winning Anybus NP40.
