The report starts in chapter 2 with an overview of technologies which are actually used in main non-railway industrial domains, like in industrial automation, in aerospace and in automotive. Some of those technologies, which obtained some importance also in the railway domain like Profinet or CIP, are presented in more detail. The chapter concludes with an outlook to upcoming technologies, which are considered to play a major role in future and which also need to be considered when defining a NG-TCN. Following the actual technology trends leads to a selection of technologies which shall be used to form the NG-TCN, namely technologies which eliminate the weaknesses of the existing, standardized, Train Communication Network. The selection of those technologies is in the scope of chapter 3. The chapter starts with a description of the actual TCN architecture and continues with listing the weaknesses and suitable measures and technologies to overcome those weaknesses in a NG-TCN. This selection of suitable technologies is then examinated in more detail within chapter 4. Basically two aspects are analysed: firstly the performance improvement by using techniques like scheduled data traffic based on synchronized clocks, and secondly the reliability increase by using sophisticated network architectures. The report closes with a conclusion giving advice about the suitability of investigated technologies for the definition of a NG-TCN.

  • 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

  • The Future of CAN / Canopen and the Industrial Ethernet Challenge by Wilfried Voss, President Esd Electronics, Inc USA
    The Future of CAN / CANopen and the Industrial Ethernet Challenge by Wilfried Voss, President esd electronics, Inc USA Industrial Ethernet technologies are a formidable challenge to CANopen as the low-cost industrial networking technology of choice. Ethernet technologies will eventually replace the majority of CANopen applications, at least in regards to new developments. For many years, Controller Area Network (CAN) and CANopen, a higher-layer protocol based on CAN, represented the best choice for low-cost industrial embedded networking. However, since the official introduction of CAN in 1986, there has been a quest to replace CAN and CANopen to overcome the most obvious shortcomings such as limited baud rate and limited network length. Industrial Ethernet technologies are currently the most formidable challenge to CANopen as the low-cost industrial networking technology of choice. Ethernet technologies will eventually replace the majority of CANopen applications, at least in regards to new developments, starting at this very moment in certain areas such as industrial control including motion control and, especially, robotics. Ironically, CAN - the underlying hardware layer of CANopen - has a far greater lifetime expectancy in the North American market than CANopen as a higher layer protocol. However, there can be too much of a good thing, and that is definitely the case when it comes to Ethernet-based fieldbus technologies. There are currently more than 20 different industrial Ethernet solutions available, all with their distinctive advantages and disadvantages, making a pro/contra decision difficult. The major question, besides the technical aspect, is which of these technologies will survive in the market, and how do they support the current need for control components.
