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.
With major product releases coming from big names like Sony, Microsoft, and Samsung, and big investments by companies like Facebook, 2015 could be the year that virtual reality (VR) and augmented reality (AR) finally pop. Here's take a look back at some of the technologies that got us here (for better and worse).
Good engineering designs are those that work in the real world; bad designs are those that don’t. If we agree to set our egos aside and let the real world be our guide, we can resolve nearly any disagreement.
The Industrial Internet of Things is bringing a previously reluctant process industry into the wireless fold. The ability to connect smart sensors to the Internet has spiked the demand for wireless devices in process manufacturing, according to the new study from ARC Advisory Group.
If you’re developing an embedded monitoring and control application, then you’ll want to take note of the upcoming Design News Continuing Education Center class, “Embedded Development Using Microchip Microcontrollers and the CCS C Compiler."
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
