Embedded EtherCAT slave interface

Anybus CompactCom M40 EtherCAT plug-in module

The Anybus CompactCom M40 for EtherCAT is a complete embedded Industrial Ethernet communication plug-in modul which enables your products to communicate on an EtherCAT network. The module acts as a EtherCAT slave interface and supports fast communication speeds, making it suitable also for high-end industrial devices.

Interchangeable with other networks

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

Get real-time EtherCAT communication

The Anybus CompactCom M40 enables fast communication between your device and the EtherCAT network. The module supports generic device profiles and 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 complete, interchangeable embedded EtherCAT slave interface plug-in module with connectors
  • ETG pre-certified for network compliance (enables faster network certification)
  • Fast data transfer: Up to 1448 bytes of process data in each direction, Up to 1500 bytes of explicit messaging
  • Very low latency <15µs
  • 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
