Anybus CompactCom B40 Modbus Serial Interface - PROFIBUS

The Anybus CompactCom B40 for PROFIBUS is a network interface in Brick format — ready-made with software and hardware to enable communication between your device and the PROFIBUS 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 B40 PROFIBUS Brick handles data lengths up to 488 bytes (244 bytes input and 244 bytes output) and supports both PROFIBUS DP-V0 and DP-V1 according to IEC61158 type 3. The PROFIBUS network implementation is made directly into the CompactCom network processor — the award-winning Anybus NP40.

Features & Benefits

  • A ready-made PROFIBUS connectivity solution
  • Supports PROFIBUS DP-V1 functionality
  • 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
  • Pre-certified for network compliance (enables faster network certification)
  • Fast data transfer: Up to 244 bytes of I/O data in each direction.
  • Automatic baud rate detection
  • Device identity customization
  • Solid security: Mandatory software signatures prevent unauthorized software to be downloaded to the module. Furthermore, encryption is used to prevent illicit copying.
