Anybus CompactCom M40 Module - PROFINET IIoT Secure

The Anybus CompactCom M40 PROFINET-IRT IIoT Secure is a complete communication module which enables your products to communicate on a PROFINET-RT or IRT network. The module 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 module, allowing seamless network integration regardless of network type. The module supports fast communication speeds, making it suitable also for high-end industrial devices and is a ready security solution which enables network-secure and encrypted communication. The module is also able to communicate with IoT protocols such as OPC UA and MQTT. This means that the PROFINET 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.

The Anybus CompactCom 40 PROFINET-IRT IIoT Secure module is a ready-made security solution which enables network-secure, encrypted communication on OPC UA Secure channels, and Secure MQTT communication. It also enables secure access to the embedded web server and secure file transfer. In order to secure the network communication over TLS, the device is equipped with a security chip providing secure key storage together with a hardware-accelerated cryptographic engine. The embedded web server includes web pages for security configuration such as certificate installation and user account management.

Security Functions

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.
