i303 - Ethernet Interface module

The i303 is an Ethernet interface card for the ionia™ system. The module includes two galvanically isolated Ethernet interfaces to connect individually to two ethernet networks. This module enables any connection to one or two ethernet networks.

Furthermore, this module helps building up redundant ethernet connections.

With the i303 a gateway to the consist network (being either on the central unit or on any other module) can easily be realised. Moreover, any other devices can be connected to the system and thus can be controlled out of one single application.

As a real time ready module, it supports all real time train protocols like IPTcom, CIP and PROFINET. It will as well cover the future TRDP protocol. Both ethernet controllers (fully compliant with IEEE802.3) are implemented in an FPGA with proven duagon IP. The real time protocol stacks are directly running on the module using a 32bit soft-core CPU.

The configuration registers and all communication data are accessible by the central unit through a fast and secure pointto- point connection (duagon serial star slave).

A built-in supervisory mechanism called «Condition Monitoring» can detect, record and report any off-limit usage, such as overvoltage, overcurrent, supply interruption, overtemperature, etc. as well as selected user-defined values.

Configuring the i303 is done easily and time saving by using one of the five methods defined by IEC 61131.

The i303 is designed for harsh rolling stock environments and is fully compliant to EN 50155 and IEC 61375.


  • Supports all real time protocols like IPTcom, TRDP, CIP and PROFINET RT
  • Both Ethernet controller support 100Mbit/s
  • Easy access to the ethernet communication by a graphical editor
  • Fully integrable into the central units application
  • No obsolescence risk due to the use of duagon® own soft-IP in an FPGA
