The communication media is either a cable modem or wireless modem. In more modern devices – in ex- ample a vending machine – the communication was using the cell-network and a SIM card was placed in each machine. It then communicated directly via a point-to-point connection with the dedicated com- puter to send sensor data – for example the fill-level – and other alarm messages to the machine owner. The business models resulting from this are mainly around logistics and maintenance as well as special condition monitoring and preventive maintenance. For example in the industrial environment, airplane turbines are sent to the airports and constantly mon- itored to send replacement parts in time to reduce the maintenance times. 5 COMMUNICATION OPC-UA INTEROPERABILITY The requirement for the communication of things The vision of IoT can only be realized, if the commu- and services inside the IoT is vastly different than to- nication of the central components is based on a day’s established structures: The IoT communication global communication standard that can fulfill the with devices will rarely happen directly.

  • 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.

David Horner1, Friedemann Grafe2, Tobias Krichler1, Helmut Mischo1, Thomas Wilsnack2) 1 TU Bergakademie Freiberg 2 IBeWa Consulting ABSTRACT Mining operations rely on effective extraction policies, which base on concerted manage- ment and technical arrangements. In addition to commodities, mining of data is the in- creasingly matter of subject in mining engineering. The Horizon 2020 project – Real-Time- Mining supports the ongoing paradigm shift of pushing mining activities from discontinuous to continuous operation. In this respect, the partners TU Bergakademie Freiberg (TU BAF) and IBeWa Consulting tackle the issue of physical and logical data acquisition in under- ground mining. The first aspect of the project addresses the ‘logical’ provision of data. Mining technology is increasingly interacting among each other and integrated into globally distributed sys- tems. At the same time, the integration of current mining devices and machineries into su- perordinated systems is still complex and costly. This means only a few number of mining operators is capable to integrate their operation technology into a Supervisory Control and Data Acquisition (SCADA) system. TU BAF presents the middleware OPC Unified Archi- tecture, which is a platform independent middleware for data exchange and technology interconnection among distributed systems. By installing a SCADA demonstrator at the research and education mine Reiche Zeche, TU BAF intends to present the technical fea- sibility of a SCADA system basing on OPC UA even for SME mining operations.

  • The Role of CAN in the Age of Ethernet and IOT

    The Role of CAN in the Age of Ethernet and IOT

    iCC 2017 CAN in Automation The role of CAN in the age of Ethernet and IOT Christian Schlegel, HMS Industrial Networks CAN technology was developed in the 1980s and became available in 1987, just as other industrial fieldbus systems like PROFIBUS or INTERBUS entered the stage of industrial communication. Beside the fact that CAN is a success in the automotive industry and used in all types of cars today, it has also made its way in many other industrial areas. About 15 years ago, new technologies based on Ethernet started to emerge, with ap- pealing and sometimes outstanding features. Some six years ago Ethernet also started to find its way into automobiles. Today, other new communication technologies are showing up on the horizon driven by the omnipresent Industrial Internet of Things. But even now, 30 years after their introduction, these “classic” fieldbus technologies are still alive – with varying success. Since CAN was initially developed with a focus for use in automobiles, CAN has certain features that still make it the best choice for many applications in automobiles and industrial areas – even when compared to the newer technologies. This paper discusses why CAN is still a valid or even better choice for certain applica- tion areas than Ethernet-based technologies, not just focusing on the advanced fea- tures provided by the enhanced capabilities of CAN FD but also highlighting how these applications benefit from the features of “classic” CAN. Looking back into history … the requirement to transmit data between … when CAN was born these ECUs but also to connect sensors and actuators to them.

    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.

    Profinet vs Profibus Pouya Aminaie1 and Poorya Aminaie2 1Department of ECE, Shiraz University, Shiraz, Iran 2 Department of ECE, Shahid Beheshti University, Tehran, Iran E-mail: [email protected] Abstract We present a step by step definition of Profinet and Profibus. We introduced different types of each of the two communication protocols. We then described the topology and performance of each one individually. Finally, the properties of them have been compared to show that which one has better performance in the industry. Keywords: Profinet, Profibus, Industrial Ethernet and Communication Networks 1. Introduction 1.1. Profinet Profinet is the abbreviation for Process Field Net, which refers to technical standards for data communication through Ethernet in the industry. These types of standards are used for gathering data and controlling industrial equipment. As can be seen from Fig.1, Profinet satisfies all the needs of industrial technologies. Fig.1 Requirement of automation technology [1] 1 The need for Profinet is felt in production automation and processing automation sections, where its use can resolve many of these needs. Profinet can be divided into two main categories, as follows: • Profinet IO • Profinet CBA 1.2. Profibus The word Profibus is taken from the phrase Process Field Bus. The scope of this protocol covers from the field level to the control level. The advantages of Profibus are as follows: 1. Low noise acceptance due to twisted pair cable being the transmission interface. 2. Appropriate bandwidth due to the use of an appropriate transmission method such as RS485. 3. Secure and non-interfering data exchange for using the token pass access method.
