Started in 2005, the InteGRail project aims to improve the performance of railways by sharing information pertaining to the Operation Management, Rolling Stock Management, Infrastructure Management and Traffic Management. Such a wide scope requires a correct picture of which technologies are available in the railway industry, which technologies are available in other domains, and which main trends are to be considered in order to provide a valid answer regarding the project goals. Recent examples concerning technology obsolescence now require the railway industry to rely more and more on widely deployed / standard technologies (standard means already in used in other domains). Benefiting from Commercial Off the Shelf technologies, and ensuring by an engineering process that railway constraints are satisfied, is nowadays a common way of working. Engineering of communication systems is now made easier thanks to processes and tools that utilize techniques like simulation, modeling and automatic code generation. This set of techniques provides support for a solution that will address the issues of obsolescence, complexity, interoperability, interchangeability, independence from … A key result of the analysis of the InteGRail User Needs was the need for a greater complexity due to the increased interactions between the different actors in the railway domain. It was decided to go beyond the current InteGRail surveys by adopting an approach where the leitmotiv was to separate applications and technologies. For this, a framework was developed looking at all the constraints of the different actors, the existing solutions, other domains, new technologies and processes. Most of the information provided in this document concerning wired communication technologies has been taken into account by the InteGRail project. This survey can be used by any system architect for the design of embedded communication systems. Enjoy the reading and make comments to the authors. Thanks a lot.

  • On Ttethernet for Integrated Fault-Tolerant Spacecraft Networks
    On TTEthernet for Integrated Fault-Tolerant Spacecraft Networks Andrew Loveless∗ NASA Johnson Space Center, Houston, TX, 77058 There has recently been a push for adopting integrated modular avionics (IMA) princi- ples in designing spacecraft architectures. This consolidation of multiple vehicle functions to shared computing platforms can significantly reduce spacecraft cost, weight, and de- sign complexity. Ethernet technology is attractive for inclusion in more integrated avionic systems due to its high speed, flexibility, and the availability of inexpensive commercial off-the-shelf (COTS) components. Furthermore, Ethernet can be augmented with a variety of quality of service (QoS) enhancements that enable its use for transmitting critical data. TTEthernet introduces a decentralized clock synchronization paradigm enabling the use of time-triggered Ethernet messaging appropriate for hard real-time applications. TTEther- net can also provide two forms of event-driven communication, therefore accommodating the full spectrum of traffic criticality levels required in IMA architectures. This paper explores the application of TTEthernet technology to future IMA spacecraft architectures as part of the Avionics and Software (A&S) project chartered by NASA's Advanced Ex- ploration Systems (AES) program.

  • PROFINET for Network Geeks
    PROFINET for Network Geeks (and those who want to be) Introduction PROFINET is an open Industrial Ethernet standard. It is a communication protocol that exchanges data between automation controllers and devices. With over 25 million installed nodes (as of 2018), PROFINET is one of the most widely used Industrial Ethernet standards worldwide. But even though millions of users are familiar with PROFINET, not all users understand how it works. This white paper starts with a brief overview of Ethernet and the 7-layer ISO-OSI model. Then, it describes how PROFINET’s 3 communication channels fit in the model: TCP/IP and UDP/IP, Real-Time (RT), and Isochronous Real-Time (IRT). 1 Ethernet The transition from using 4-20 mA analog signals for I/O communication to digital fieldbuses provided the benefits of reduced wiring, access to network data, and robust diagnostics. The later transition from digital fieldbuses to Ethernet was also similarly a shift to a more modern technology. Ethernet incorporated and improved upon the benefits of fieldbuses. Ethernet is ubiquitous and PROFINET uses standard Ethernet. Ethernet gives PROFINET the ability to provide faster updates, more bandwidth, larger messages, an unlimited address space, and even more diagnostic capabilities. Also, as commercial Ethernet evolves, PROFINET can take advantage of these physical layer improvements. Figure 1 ISO-OSI Model The ISO-OSI Model Ethernet-based communications can be represented by a seven-layer model: the ISO/OSI Reference Model. The model generically describes the means and methods used to transmit data. Each layer has a specific name and function, as shown in Figure 1.

PROFINET is particularly useful for industrial automation systems and process control networks, in which motion control and precision control of instrumentation and test equipment are important. It emphasizes data exchange and defines communication paths to meet speed requirements. PROFINET communication is scalable on three levels: • Normal non-real-time communication uses TCP/IP and enables bus cycle times of approximately 100 ms. • Real-time communication enables cycle times of approximately 10 ms. • Isochronous real-time communication enables cycle times of approximately 1 ms. Note The switch does not support isochronous real-time communication channels. PROFINET IO is a modular communication framework for distributed automation applications. PROFINET IO uses cyclic data transfer to exchange data, alarms, and diagnostic information with programmable controllers, input/output (I/O) devices, and other automation controllers (for example, motion controllers). PROFINET IO recognizes three classes of devices: • IO devices • IO controllers • IO supervisors Cisco IE 3000 Switch Software Configuration Guide OL-27302-02
