The D547 is a compact PROFINET to Ethernet gateway with Sibas PN services. The integrated Ethernet controllers, designed by duagon, feature hardware prioritisation and very low jitter. The PROFINET interface offers a full-featured 3-port switch to enable ring topologies and daisy-chaining. Furthermore, the bypass relays ensure the ring topologies integrity in case of malfunction.
The Ethernet interface is prepared for the “Ethernet on traction vehicles” standard IEC 61375-3-4. It supports various Ethernet protocols such as TRDP, CIP, IPTCom, UDP or TCP/IP.
Both the PROFINET and the Ethernet interfaces are fully complaint with IEEE 802.3 and supports features like Auto- Polarity, Auto-Negotiation and Auto-MDI-X.
The gateway is equipped with a 32-bit embedded softcore processor, that handles the Ethernet communication stacks and the gateway application.
The gateway integrates the magnetics with a galvanic isolation of 1.5kVrms, the PHY and the complete Ethernet protocol controller.
A software development library with an easy to use API to the PROFINET and Ethernet interface is provided and offers a high flexibility to the designer of the gateway application using standard C language. The gateway is delivered with a demo application to support the development.
The D547 is powered directly from the train battery (24V to 110V, wide range power supply). There is no need for an additional external power supply.
The D547 fulfils the Safety Integrity Level 0 defined by EN 50128 and EN 50129 and is designed for harsh rolling stock environments.
