MEN Mikro F302 - 3U cPCI/CompactPCI® Quad Fast Ethernet / Real-Time Ethernet Interface

4x 10/100 Ports, M12 Connectors, -40 to +85°C Qualified

Introduction

MEN Mikro's F305 is a 3U CompactPCI 100-Mbit/s networking controller with a strong focus on railway applications. It comes in a compact 4 HP, one-slot width even with its rugged M12 connectors. 

The card provides four Fast Ethernet channels, supporting full-duplex or half-duplex with 10BASE-T and 100BASE-TX physical layers for distances up to 100 m.

As an assembly option, the board is available with or without a real-time Ethernet controller and extended connectivity, making it scalable to system requirements.

Real-Time Ethernet for MTCS

The F305 has a special function as the real-time Ethernet component inside the controller of the MEN Modular Train Control System. MTCS is a platform to perform safe train control functions, focusing on rolling stock applications like Automated Train Operation (ATO) or Automated Train Protection (ATP). It usually consists of the MH50C MTCS controller system and safe remote I/O boxes.

Ring Topology

The distributed MTCS subsystems are connected via RT Ethernet in ring topology, which tolerates single failures. For example, in case of a broken cable, the entire system is still fully operational, as all MTCS subsystems can still be reached from the other end of the ring. The F305 offers the capability of short-connecting two front channels. This is done by the host via software. 

Access to System-Internal MTCS I/O Cards 

In MTCS systems the F305 has a direct link to I/O cards on the same backplane, using the MTCS EBUS, power supply, and address lines. As the F305 itself has no special safety mechanisms and certification, the board must be considered as a black channel.

EN 50155 Rolling Stock and EN 50121-4 / EN 50125-3 Wayside Compliance

The F305 was fully designed to meet the requirements both for vehicle and wayside applications. Its operating temperature complies with the class TX specifications of -40 to +70 °C (10 minutes up to +85 °C). Standard boards include conformal coating. Along with its railway standard compliance and long-term availability of a minimum 10 years, the F305 is a rail-ready component, saving time to arket and costs.
