Fieldbuses – it’s a competition, not a war – I said back in 2006 in The Great Thing about Standards is… in defense of competing fieldbus and Industrial Ethernet standards. Now my friend James Powell weighs in with a similar conclusion in Selecting an open digital protocol in process automation.
He begins: “If you want to make it to the finishing line quickly, you need a fast horse. To make top times, however, it helps to have two or more high-performance horses in the race. Competition brings out the best in performance, and nowhere is this truer than in the world of industrial protocols.” You should read the whole thing.
