At the 2011 Siemens Automation Summit in Orlando, we jumped straight in. Dennis Inverso, from DuPont, conducted a welcome, organized a safety moment and then began to talk about the relationship between DuPont and Siemens since 1990. In 2006, DuPont's DCS engineering team recommended that Siemens had the best offering globally, and was the best in connectivity between drives, PLCs and DCS.
