Anybus CompactCom C40 Chip

The Anybus® CompactCom™ C40 is a high-performance network communication solution in chip format. It consists of the Anybus NP40 network processor loaded with the software you need to connect an industrial device to different fieldbus or Industrial Ethernet network.
The C40 Chip is available under Licensing from HMS.


The Anybus CompactCom C40 solution includes all the functionality needed to handle communication between your device and any industrial network. A chip-based solution gives you a lot of freedom to design your own hardware and add connectors around the chip.


The Anybus NP40 network processor enables integration of optimized infrastructure solutions like high-performance Ethernet switches with on-the-fly processing and cut-through switching with very low latencies. This multi-network chip eliminates the need for different external communication ASICs and FPGAs drastically reducing the design complexity and cost.

Anybus CompactCom C40 Chip

Features and benefits

  • Multi-network connectivity in a chip - Select from: PROFINET, EtherNet/IP, EtherCAT, Modbus TCP, Powerlink, BACnet/IP,  PROFIBUS, CC-Link and DeviceNet
  • A ready-made solution minimizing your programming efforts
  • New and future network updates and enhancements maintained by HMS
  • Fast data transfer: up to 1500 bytes of process data in each direction
  • Possibility to send a complete Ethernet frame via the socket interface (up to 1500 bytes). Support for more than 20 socket connections
  • Very low latency <15μs (EtherCAT)
  • Clock-synchronous operation for high-speed networks
  • Event-based interface method enables easy to access input and output data at any time
  • Fast, event-based application hardware interfaces: 8/16-bit parallel and high speed SPI. I/O (shift register interface) is also available
  • Use the same chip for different Ethernet networks. Simply download new firmware to enable communication with another network
  • Firmware management tool enables easy download via FTP or serial connection
  • Flash-based file system with two-disc access (internal and external)
  • Support for safety networks via the black channel to the IXXAT Safe Solutions.
  • Solid security: Mandatory software signatures prevent unauthorized software illicit copying.
