    • Fast data transfer: up to 1500 bytes of process data each way (latency 15µs)
    • Unique way of handling device profile integration (Drive, Motion, Semi, Others)
    • Safety-ready. Combine with the IXXAT SafeT100 for safety network integration
    • Uses network encryption technologies to keep your devices safe and secure

    Anybus CompactCom B40 Brick - EtherNet/IP IIoT Secure

    The Anybus CompactCom B40 EtherNet/IP IIoT Secure is a high-performance network interface in Brick format, that provides industrial devices with instant EtherNet/IP connectivity. The B40 Brick is conformance tested and communicates with the host device via the patented Anybus CompactCom host interface. Any device that supports this standard can take advantage of the features provided by the B40, allowing seamless network integration regardless of network type. The B40 Brick supports both linear and ring network topology and is a ready-made security solution which enables network-secure and encrypted communication. The B40 Brick is also able to communicate with IoT protocols such as OPC UA and MQTT. This means that the EtherNet/IP data is processed as usual by the CompactCom - and data from the device can also be sent to an IT system via OPC UA or MQTT.

    Certificates are a main component in secure communication. They are used to identify the owner of the certificate. A node will trust a certificate if it trusts the Certificate Authority (CA) that has issued the certificate. Trusted certificates are used to ensure secure communication.

    Which certificates to use, depend on the installation. HMS Networks offers a tool that generates device and CA certificates, to be used during development.
