Embedded PROFINET IRT slave interface

Anybus CompactCom B40 PROFINET IRT brick for PCB-assembly

The Anybus CompactCom B40 for PROFINET-IRT is a complete embedded Industrial Ethernet communication plug-in modul which enables your products to communicate on an PROFINET-IRT network. The module acts as a PROFINET-IRT slave interface and supports fast communication speeds, making it suitable also for high-end industrial devices.

Add your own connectors and peripherals

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

Interchangeable with other networks

By implementing the CompactCom B40 into your product line, you will have instant embedded access to any other industrial network by simply plugging in another Anybus brick .

Get real-time PROFINET-IRT communication

The Anybus CompactCom B40 enables fast communication between your device and the PROFINET-IRT network. The module supports generic device profiles, PROFIenergy and a black channel interface for PROFIsafe implementation. In addition, it comes with a dual port switch implemented in the network processor — the award-winning Anybus NP40. With its fast data transfer and very low latency, it's the perfect match for even the most demanding industrial applications.

Features and benefits

  • A ready-made embedded PROFINET-IRT slave interface for PCB assembly
  • Easy mounting to your host PCB design
  • PNO pre-certified for network compliance (enables faster network certification)
  • Fast data transfer: Up to 1440 bytes of process data in each direction
  • Very low latency
  • 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
  • IIoT ready: (EoE) Includes Email Client, Web server with customizable content, SSI functionality and FTP server
  • Extended flash-based file system with two-disc access (internal and external)
  • Transparent Socket Interface handling the complete Ethernet frame (support for 20 socket connections)
  • Solid security: Mandatory software signatures prevent unauthorized software to be downloaded to the module. Furthermore, encryption is used to prevent illicit copying
  • Short in-design with free assistance from Twincomm and HMS ensures a fast time to market
