Technology Updates (Hanover Fair 2009 Report 3)

There was news of progress in a number of technology areas: IO-Link, wireless, PROFIBUS, and PROFINET. IO-Link products are appearing more rapidly.  IO-Link is not a fieldbus, but allows digital communications over the device’s cable.  This led me to characterize… Read more »

SPS Drives 2008 Report: IO-Link

I’ve previously described IO-Link as HART for discrete.  IO-Link was widely displayed at this year’s show.  For more explanation, how it fits with PROFIBUS and PROFINET, reports, photos, and video, click here.
