Anybus CompactCom B40 Modbus Serial Interface - PROFINET

The CompactCom B40 Modbus Serial PROFINET IRT enables simple communication between your Modbus device and the PROFINET IRT or RT network.

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

The CompactCom B40 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 is ideal for device manufacturers who are looking for a semi-integrated solution where connector flexibility, size and cost are key elements.

The B40 PROFINET IRT Brick handles data lengths up to 2800 bytes (1400 bytes input and 1400 bytes output). The PROFINET IRT network implementation is made directly into the CompactCom network processor — the award-winning Anybus NP40.
