Get a transparent Ethernet channel through the Anybus CompactCom 40-series 

Users with high-end processors and software, such as Linux with built in TCP/IP stack and IT services, get a transparent Ethernet channel. The Transparent Ethernet channel gives you complete freedom to create and implement your own IT solution in your host application processor.

Anybus CompactCom 40 Ethernet products are available in a special version that includes a Transparent Ethernet interface. This means that industrial Ethernet protocol data (for example PROFINET or EtherNet/IP) is processed as usual by the CompactCom while all other Ethernet data passes straight through the module transparently — speeding up the network communication while allowing you to develop your own IT-functions.

Under the hood

The block diagram above shows how the communication is handled inside the Anybus CompactCom. Inside, there is a “traffic separator” which is able to detect and separate industrial Ethernet protocol data from other Ethernet data.

The real-time data is processed by the CompactCom while other Ethernet data is sent routed via the Reduced Media Independent Interface (RMII) interface for transparent distribution to the application.

The Transparent Ethernet RMII interface emulates a PHY operating at 100Mbit/s full duplex. The RMII interface is connected directly to an Ethernet MAC in the host application processor.
