Sparked by a blog post and an article in Computer magazine, I had to think about Web 1.0, 2.0, and 3.0. There’s an easy comparison or two between Web 1.0 and Web 2.0 at the Vovici blog. The Web 3.0 article was in Computer magazine, “Web 3.0 Emerging.” (The article has to be purchased unless you are a member of the Computer Society, which if you read this blog, you should be.) It starts out “Facebook is so 2008.” The author’s definition of Web 3.0 is Web 2.0 plus Semantic Web technologies.
The Industrial Automation connection?
Direct wiring is equivalent to Web 0.0 (Dark Ages, pre-Bulletin Boards even).
Using a fieldbus like PROFIBUS moves you to Web 1.0.
Adding PROFINET gets you to Web 2.0 in the sense that PROFINET allows “collaboration” with easy peer-to-peer integration.
Web 3.0 (if there really is such a thing) might be equivalent to PROFINET’s vertical integration allowing data from the plant floor transforming into information in production systems (MES, EAM, ERP).
