  • 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.

  • Fieldbus Communication: Industry Requirements and Future Projection
    MÄLARDALEN UNIVERSITY SCHOOL OF INNOVATION, DESIGN AND ENGINEERING VÄSTERÅS, SWEDEN Thesis for the Degree of Bachelor of Science in Engineering - Computer Network Engineering | 15.0 hp | DVA333 FIELDBUS COMMUNICATION: INDUSTRY REQUIREMENTS AND FUTURE PROJECTION Erik Viking Niklasson [email protected] Examiner: Mats Björkman Mälardalen University, Västerås, Sweden Supervisor: Elisabeth Uhlemann Mälardalen University, Västerås, Sweden 2019-09-04 Erik Viking Niklasson Fieldbus Communication: Industry Requirements and Future Projection Abstract Fieldbuses are defined as a family of communication media specified for industrial applications. They usually interconnect embedded systems. Embedded systems exist everywhere in the modern world, they are included in simple personal technology as well as the most advanced spaceships. They aid in producing a specific task, often with the purpose to generate a greater system functionality. These kinds of implementations put high demands on the communication media. For a medium to be applicable for use in embedded systems, it has to reach certain requirements. Systems in industry practice react on real-time events or depend on consistent timing. All kinds are time sensitive in their way. Failing to complete a task could lead to irritation in slow monitoring tasks, or catastrophic events in failing nuclear reactors. Fieldbuses are optimized for this usage. This thesis aims to research fieldbus theory and connect it to industry practice. Through interviews, requirements put on industry are explored and utilization of specific types of fieldbuses assessed. Based on the interviews, guidelines are put forward into what fieldbus techniques are relevant to study in preparation for future work in the field. A discussion is held, analysing trends in, and synergy between, state of the art and the state of practice.
