D502 - RS485/422 to Ethernet Gateway
- TCP/IP, UDP
- IPTCOM / TRDP
- CIP, PROFINET
The D543 is a compact PROFINET to MVB 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 PROFINET interface is fully compliant with IEEE 802.3 and supports features like Auto- Polarity, Auto-Negotiation and Auto-MDI-X. The D543 integrates the magnetics with a galvanic isolation of 1.5kVrms, the PHY and the complete protocol controller.
The gateway offers one line redundant MVB interface with selectable physical layer – ESD+ or EMD. duagons own MVB controller is implemented in an FPGA and supports all 4096 process data ports. An additional 32-bit softcore handles the complete message data stack with an easy-to-use interface.
The MVB interface fully complies to the TCN standard IEC61375 up to MVB class 4. The optionally includable Bus Administrator manages the complete MVB network. The gateway is equipped with a 32-bit embedded softcore processor, that handles the Ethernet communication stack for the service interface and the gateway application.
A software development library with an easy to use API to the PROFINET and MVB 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 development.
The D543 is powered directly from the train battery (24V to 110V). There is no need for an additional DC/DC converter. The D543 fulfils the Safety Integrity Level 0 defined by EN 50128 and EN 50129 and is designed for harsh rolling stock environments.
