Euagon”_2. IntroductionGeneral Features The i303 is an Ethernet interface card for the ionia™ system. The module includes one or two galvanically isolated Ethernet interfaces to connect individually to up 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 realized. Moreover, any other devices can be connected to the system and thus can be controlled out of one...

Euagon”_2.1 How to Get Started This document describes the hardware and soft-IP functionality of the i303 module. These modules are part of the modular ionia™ system, they are not intended to be used as standalone components. The ionia™ system is configurable online at http://ionia.duagon.com/ For information about programming the ionia™ system, please refer to: • ionia™ Get Started Documentation (d-007724-nnnnnn). The i303 comes with several order options, these are described in the section "Ordering Information", pag. 17. For additional information, please visit our home page www.duagon.com....

The module is programmable by the central processing unit using a comfortable programming environment that is based on IEC 61131 LD, FBD, ST, IL or SFC. • ionia™ Get Started Documentation (d-007724-nnnnnn), and Firmware update is handled by the central processing unit (see i101/i102/i103 for further information). In addition it can be performed manually using built in HTTP server. The ionia™ system uses a 100Mbit/s duagon star slave (DSS) backplane communication. Each module is connected with the central processing unit over a dedicated bidirectional link. The link is used to exchange all of...

2. A second independent Ethernet Protocol stack can run on ETH1. 3. ETH1 can be used for redundancy concepts, e.g. ring structure, Parallel Redundancy Protocol PRP (IEC 62439), etc. For options 2. and 3. please call duagon for more information. On ETH0 and ETH1, different railway specific Ethernet protocols are available as an option (see also "Ordering Information", page 17): The i303 supports IPTCom Process Data, IPTCom Message Data and IPTDir service. Other IPTCom functions are available on request. On the host system, the application can use IPTCom through the host driver. The future TRDP...

Basic Function Blocks DC/DC S2 cap Backplane SuperVisor Figure 2: Schematic of the i303's architecture The logic circuits are build using programmable logic device. This ensures the versatile change of e.g. controller specifications, bug fixes after hardware production and future portability to new silicon technologies. The soft-core CPU manages operation of the device and communicates with ionia™ using direct connection over the Backplane. Ethernet MACs are implemented in the FPGA...

The front panels of the i303 are shown in Figure 3. Figure 3: Front panel of the i303 with single (left) and double (right) interface Ethernet interface has M0 2 type connector with D coding. It supports following features: • full duplex • auto negotiation (disabled by default - see IEC 60 375-3-4) • auto sensing • auto polarity • 100m cable length over CAT5e (see Ethernet Cabling) Second Ethernet interface (optional) has exactly same features as first interface. It can be fully independent or can be coupled with first interface (see also "Ethernet Interface ETH1 (optional)", page 7). • The cable...

Buagori’ • The cable shield has in all nodes the same connection to the device housing. • The signal lines are galvanically insulated to the i303 inner logic and to each other (ETH0 to ETH1). This has as a consequence, that all housings are connected together. Within the vehicle concept it must be ensured, that there are no ground potential differences that may harm the cable shield or the connectors. For information about counterparts for X1 and X2 check IEC 61076-2-101. A CAUTION. Any CAT5e cable is sufficient to establish Ethernet connection. However to maintain reliable connection in harsh...
