Are you going to Hanover Fair…

Not Scarborough Fair… and no parsley, sage, rosemary, or thyme.  Are You Going to Hanover Fair could have been the tune at Hanover Fair on Monday (with apologies to Simon and Garfunkel).  Monday attendance seemed off from prior years; one company said they had 20% fewer leads.  Fortunately Tuesday picked up and Wednesday was very busy;…

Manchester-Encoded Safety Airport Lounge

En route to Hanover I am spending some hours in the Manchester (UK) airport… too many, actually, but more than enough time to read and ponder a Briefing in Friday’s ARCwire on HIMA’s Safety Systems.  In the last paragraph this bit causes me to wonder: “HIMA offers open integration solutions based on common hardware and…

“Safety has evolved from being a cost burden and “necessary evil” to a strategy for improving productivity and reducing downtime.” –from the “The Business Case for Safety” section of the new ARC White Paper, PROFIsafe: Networked Safety for Process and Factory Automation. We engineers sometimes get so excited about the technology we forget about the…

Live from the PROFINET one-day training event in Nashville – lunch is over and we are resuming with the PROFINET IO demo.  Good questions at this event and a blend of Control Engineers and IT.  I love to see that gap overcome.  At these events, when we ask if there is cooperation or tension between…

Somewhere over the Atlantic

I’m relatively awake but not necessarily happy to be.  But while I am, I will compose some Hanover Fair news to post when I land. First, news about PROFIBUS and PROFINET.  A number of companies make development kits for device manufacturers to get moving quickly on PROFINET products.  (We’ve recently confirmed that we will schedule…

Stuck in the office

Kind of a long stretch with no travel.  Today Mike and Mike are handling the PROFIBUS in the Process Industry one-day training event in San Juan.  Sure, I go to Canada for a week and the boss goes to Puerto Rico.  (He doesn’t do “cold.”  We all live in Arizona for a reason, I guess.)…

Going back to Austin

I didn’t realize how long it had been since I’d been here.  Bergstrom was an air base then and now it’s the Austin airport.  I guess my youngest graduated from UT longer ago that I realized. The training class was terrific.  Man, I love this technology!  One of the things we do to break up…

National Manufacturing Week Part 2

I set most of today aside to visit the show before heading off to Austin for the PROFINET one-day training event there tomorrow.  But I saw all of the show I needed to during lunchtime yesterday.

National Manufacturing Week

At National Manufacturing Week today.  Well, the conference actually.  I participated in an all-day session moderated by Control Engineering’s Mark Hoske: a round-up of 7 Industrial Ethernet technologies.  Each technology was presented and the session concluded with a round table panel discussion.  Modbus and Ethernet/IP sent slides but no representative.  Mark went through the slides…

PTO one-day training events in Canada

I’m just back from the PROFIBUS and Process one-day training events in Montreal and Toronto only to find snow in the mountains north of our Scottsdale office.  I did not mean to bring the snow back with me! We had a lively group in each venue and a lot of good questions (and answers).  There…
