Spring – When a Young Man's Fancy Turns to PROFINET

There are a lot of similarities between baseball and PROFINET: Green.  They are both associated with the color green. Green grass on which to play baseball; green cable over which to send PROFINET. Pitch speed. Some pitchers’…

Engineer’s Holiday

No PROFIBUS or PROFINET in this post; it’s off those topics, but still engineering related.  A Sightseer’s Guide to Engineering lists six engineering sights to see in Arizona.  With this past weekend’s travels I’ve now seen five.  (I have not been to Kitt Peak National Observatory yet – although I have been to the Lowell…

PROFINET Q & A from Louisville

Our course evaluation form asks some specific questions with check box choice answers, but I think the most interesting are the open-ended questions.  Two of those are topics you would like to see covered in greater detail and topics in less detail.  In Louisville there were a few responses for topics attendees thought we should…

Long Beach Process Q & A

From the plane bound for Louisville, here is one of the comments from the PROFIBUS in the Process Industries one-day training class in Long Beach: “I think PROFIBUS is more complicated than Foundation Fieldbus as far as device connections go.” At the physical layer there is no difference between FF and PROFIBUS PA so the…
