FSE

Freely available software interfaces for efficient data exchange

 

Frauscher Safe Ethernet FSE

Modern signalling systems require a high degree of integration of all subsystems and therefore high-performance interfaces. An efficient exchange of data between the sub-systems can only be achieved with software interfaces and Frauscher has developed the Frauscher Safe Ethernet FSE for this purpose.

The FSE protocol is the ideal solution for integration into systems without their own software protocol. It has been developed especially for a very wide range of applications in the field of wheel detection and axle counting. Frauscher makes the FSE available free of charge and provides its customers with support in the implementation.

FSE has become the standard

FSE has become the standard

The FSE interfaces are now being used on a variety of hardware platforms by customers in many different countries. An increasing number of system integrators are holding discussions with Frauscher with a view to coordinating the details or implementing the FSE protocol. If this trend continues, FSE will become a de facto standard in the field of wheel detection and axle counting.

Application data

Performance parameters when implementing with FAdC

  • A COM-FSE communication board is able to evaluate and transmit data from up to 40 AEB boards
  • Communication via Ethernet using an interlocking
  • Notifications are sent in two directions:
    • Notifications that are sent by COM-FSE communication board from FAdC to the interlocking
      • Information on the status of the track section (FMA)
      • Current number of axles in a track section (FMA)
      • Indicator of train length
      • Information on direction, speed and wheel diameter
      • I/O infomration of the AEB/IO-EXB
    • Notifications that are sent from the interlocking to the COM-FSE communication board resetting information
      • Checkbyte
      • Reset information
      • I/O information of the safety system
  • Max. number of bytes for application data on sender side (notifications from FAdC to interlocking) = 201 Bytes
    • 1 x checkbyte
    • 40 x information on status of track section 1 (FMA 1)
    • 40 x information on status of track section 2 (FMA 2)
    • 80 x current number of axles in a track section (FMA) (for FMA 1 and FMA 2)
    • 80 x indication of train length (for FMA 1 and FMA 2)
    • 40 x information on direction
    • 40 x information on speed
    • 40 x information on wheel diameter
    • 40 x I/O information of the AEB
  • Max. number of bytes for application data on the recipient side (notifications from the interlocking to FAdC) = 84 Bytes
    • 1 x checkbyte
    • 40 x reset information track section 1 (FMA 1)
    • 40 x reset information track section 2 (FMA 2)
