Products have been available for some years now and they are starting to appear in very large projects in the automotive industry.

Automotive Instigates PROFIBUS, then PROFINET

At the PI North America General Assembly Meeting last month we had an automotive theme.  This put me in a reflective mood, thinking about the roots of PROFI. In 1989 the German automotive industry asked the government to help them by creating a fieldbus.  Thirteen companies and 5 universities responded to the call and created…

SPS Show Report 2010, Around the Show

Before I had time to leave the PI booth, at the Phoenix Contact station I was handed a Tiger chip.  Except they’re not calling it “Tiger” anymore; it’s just called TPS-1.  This ASIC is intended for simple PROFINET IO devices.  Right next to their station was the Innovasic station.  Keith Prettyjohns introduces their solution in…

Go Green for Money, not Image

I don’t do well with the whole politically correct thing.  In the one-day training classes we even talk about <gasp> multi-point grounding.  And we talk about the reasons to use PROFIenergy, including AGW (Anthropomorphic Global Warning*).  I guess I’m a bit of a skeptic, but it doesn’t matter – it’s still a reason to use…
