Unmanaged Industrial Ethernet Switch

The G304 is an unmanaged 3U Ethernet switch implemented as a CompactPCI Serial board. It occupies one peripheral slot, using a 4 HP front panel with 4 Gigabit Ethernet ports on RJ45 or X-coded M12 connectors, and one direct Ethernet connection to the CPU card using PCI Express on P1. A P6 connector can optionally extend the number of Ethernet channels available on the board to six.

Reliable Communication System Component

The G304 supports full-duplex and half-duplex operation with auto-negotiation, high-speed nonblocking store-and-forward switching. Its built-in test mechanisms make the G304 an even more reliable component in the communication system.

In addition, the switch can act as Power over Ethernet Plus (PoE+) Power Sourcing Equipment (PSE), supplying other devices on all ports with up to 30 W (class 0, 1, 2, 3, 4) per port for power according to IEEE 802.3 Section 2 – Type 1 and 2 (formerly known as IEEE 802.3at). The maximum power available for one G304 is limited to 61.6 W, according to CPCI-S.0 specification.

Compliant to Railway Standards

The board is specifically designed for rugged mobile communication systems. It is, for example, compliant with the EN 50155 railway standard, supports a -40 °C to +85 °C operating temperature and rail-ready versions are coated.

The MEN G229 is an I/O expansion board for CompactPCI Serial for adding often required functions to a CPU board on a single slot. It can be used, e.g., as a main boot device for a server CPU.

The board is designed and tested for the railway and industrial market. It provides 3 USB 3.2 Gen 1×1 ports and isolated RS232 and RS422/485 interfaces, for either service or continuous operation in a railway or industrial environment.

For data storage or as a boot medium an M.2 slot supporting NVMe is provided on the board. It provides a fast boot time as it is connected via a PCI Express x1 link.

The G229 is a low-power solution for the extended temperature range.

MH50C is a central controller of the duagon SAFE CONTROL (d-SC) System. It is a modular system platform usable for safety-critical train applications like train control, automatic train operation (ATO) and automatic train protection (ATP) up to SIL 4 (EN5012x) or SIL3 (IEC61508).

Modular I/O Configuration

Being based on modular 40 HP CompactPCI, the system is always configured with a safe system CPU, a real-time Ethernet card, a power supply unit and a shelf controller. Other cards are added as built-to-order (BTO) options or by the user. The safe I/O cards support the common I/O requirements requested in trains.

The composition of safe CPU card, safe train I/Os and interfaces, such as MVB, CAN or serial interfaces to connect to legacy train equipment makes the controller ideal for use in safety-critical rolling stock applications.

Application-Ready, Open Platform

The MH50C is an application-ready, open platform. This means that the user adds his application based on the basic operating system and driver software.

Part of duagon SAFE CONTROL System

d-SC is a modular SIL 4 certifiable family of CompactPCI-based standard products usable for every kind of safety-critical railway application – from a single function to the main control system of the train. It can be configured to control anything in the train that requires functional safety with requirements from SIL 1 up to SIL 4.

d-SC communicates via standard real-time Ethernet and can be configured to interface to any type of consist fieldbus network like MVB, CANopen, Profinet etc. This makes it easy to integrate into a TCN network as well as into regionally different Train Control Systems like ETCS, CTCS, ATCS or Klub-U. The high level of flexibility of d-SC results in significant cost and time savings during computerization of the train.

Certification and Standards Compliance

d-SC components come with certification packages and complete support for the safe operating system QNX, including safe protocols, and provides the technical possibility to run a safety PLC, again saving cost and time for implementation and for certification of the final system. d-SC is developed according to EN 50128 and EN 50129 standards and complies with the environmental requirements for railway applications: temperature class TX, shock, vibration, humidity, dust, isolation, PSU hold-up times, EMC regulations etc.

Mounting and Cooling Options

The system can be wall or rack-mounted, and is cooled.
