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

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…
