  • 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.

Based on published material it shows the technical principles of the various approaches and tries to put these into perspective. The content given represents my best knowledge of the systems introduced. Since the company I work for is member of all relevant fieldbus organizations and supports all important open fieldbus and Ethernet standards, you can assume a certain level of background information, too. The slides were shown on ETG Industrial Ethernet Seminar Series in Europe, Asia and North America as well as on several other occasions, altogether attended by several thousand people. Among those were project engineers and developers that have implemented and/or applied Industrial Ethernet technologies as well as key representatives of some of the supporting vendor organizations. All of them have been encouraged and invited to provide feedback in case they disagree with statements given or have better, newer or more precise information about the systems introduced. All the feedback received so far was included in the slides. You are invited to do the same: provide feedback and – if necessary – correction. Please help to serve the purpose of this slide set: a fair and technology driven comparison of Industrial Ethernet Technologies.

  • Industrial Ethernet Facts Compares PROFINET (RT, IRT), POWERLINK, Ethernet/IP, Ethercat, and SERCOS III, I.E
    Luca Lachello Wratil Peter Anton Meindl Stefan Schönegger Singh Karunakaran Bhagath Huazhen Song Stéphane Potier Preface Outsiders are not alone in finding the world of Industrial Ethernet somewhat confusing. Experts who examine the matter are similarly puzzled by a broad and intransparent line-up of competing systems. Most manufacturers provide very little information of that rare sort that captures techni- cal characteristics and specific functionalities of a certain standard in a way that is both com- prehensive and easy to comprehend. Users will find themselves even more out of luck if they are seeking material that clearly compares major systems to facilitate an objective assessment. We too have seen repeated inquiries asking for a general overview of the major systems and wondering “where the differences actually lie”. We have therefore decided to dedicate an issue of the Industrial Ethernet Facts to this very topic. In creating this, we have tried to remain as objective as a player in this market can be. Our roundup focuses on technical and economic as well as on strategic criteria, all of which are relevant for a consideration of the long-term via- bility of investments in Industrial Ethernet equipment. The arguments made in this publication were advanced and substantiated in numerous conversations and discussions with developers and decision-makers in this field. We have made every attempt to verify claims whenever practically possible. This document must not be modified Despite all our efforts, though, we were unable to ascertain exact, verifiable information on without prior consent of its publisher. some aspects, which prompts us to ask for your help: if you would like to propose any Passing on the document in its entirety amendments or corrections, please send us an e-mail or simply give us a call.
