The Future of CAN / CANopen and the Industrial Ethernet Challenge – Wilfried Voss, President esd electronics, Inc USA

The Future of CAN / CANopen and the Industrial Ethernet Challenge - 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, 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 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 very difficult. The major question, besides the technical aspect, is which of these technologies will survive in the market and how they support the current need for control components. In all consequence, the battle between these technologies is a mere marketing battle and only time will tell who will win.


This presentation will elaborate on the future of CAN and CANopen in the North American market. It will also address the need for faster fieldbus systems and narrow the field of potential winners in the Ethernet race. A special focus will be on the conversion of CANopen application into EtherCAT.


Introduction to EtherCAT – Joey Stubbs – North American Representative, EtherCAT Technology Group

This presentation is an in-depth introduction to EtherCAT, the fastest industrial Ethernet fieldbus available, capable of updating 1000 distributed I/O in 30µs, 200 16 bit analog I/O in 50µs, or 100 servo axes in 100µs. EtherCAT sets new standards for real-time performance and topology flexibility, while meeting or undercutting standard industrial fieldbus cost levels. EtherCAT features include IEEE 802.3 compatibility, high precision device synchronization, a cable redundancy option, flexible topology, and a native functional safety protocol (SIL3). EtherCAT is an international standard (IEC, ISO and SEMI). EtherCAT is represented by the EtherCAT Technology Group (ETG) with over 1000 member companies from 45 countries around the world.


Ethernet in the Factory: Lessons Learned – James Ingraham - Software Development Team Leader Sage Automation, Inc

For about ten years, Sage Automation, Inc. has been using Ethernet on the factory floor. A builder of gantry robots and other automation equipment, Sage has used industrial Ethernet for controller-to-controller communications, control of I/O and variable speed drives, motion control, interfacing to vision sensors and barcode scanners, and communicating with the enterprise network. Unsurprisingly, not everything has gone smoothly. Primarily, Sage has worked with EtherNet/IP, but many of the lessons learned apply to other Ethernet protocols as well. This presentation will talk about what went wrong, what went right, the pros and cons, and how we solved some of the problems that industrial Ethernet creates.
