Anybus CompactCom M40

For both general or demanding high performance applications

The cutting-edge Anybus CompactCom 40-series is based on the award-winning Anybus NP40 network processor. It is especially suitable for both general purpose and for high-end applications with large I/O data transfer, fast network cycles and synchronization demands.

    • Combines major fieldbus networks with high performance real-time Industrial Ethernet
    • Common Ethernet module allows you to download your chosen Ethernet protocol to the module
    • Unique way of handling device profile integration (Drive, Motion, Semi, Others)
    • Safety ready - Can be combined with the IXXAT SafeT100 to provide implementation of safety networks
    • Uses network encryption technologies to keep your devices safe and secure
    • 1st generation CompactCom 30-series available for additional networks 

    Anybus CompactCom M40 Module - Modbus TCP

    The Anybus CompactCom M40 for Modbus TCP is a complete communication module which enables your products to communicate on an Modbus TCP network. The module supports fast communication speeds, making it suitable also for high-end industrial devices.


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


    The Anybus CompactCom M40 enables fast communication between your device and the Modbus TCP 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.
