While most engineers argue Ethernet TCP/IP is inappropriate for an I/O bus, Gerd Hoppe, President of Beckhoff North America, says his company is going in the opposite direction with its new product RTEthernet—introduced in Europe in November 2002 and just now available here in the U.S. Beckhoff 's software engineers, old hands at tinkering with the Windows operating system, have devised a way to communicate directly with a standard COTS Ethernet controller card using short, 7-microsecond telegrams. One of these tiny telegrams could contain the status of as many as 368 I/O points. Regular TCP messages are held temporarily in a buffer while the telegrams pass through the system. Aptly described as an "onion ring" design, it can encapsulate any fieldbus protocol inside its Ethernet telegrams, giving RTEthernet potential compatibility with dozens of different fieldbus systems.
The transformative nature of designing and making things was the overarching, common theme at separate conferences held in Boston by two giants in the PLM space: Autodesk, with its Accelerate 2015, and Siemens’s Industry Analyst Conference 2015.
