May 2012 Digital Edition

The May issue of Control addresses the question, is industrial control security a safety issue. Also included, the real reason variable-frequency drives (VFDs) are such a hard sell to many process engineers--it may not be what you think--and Hall of Fame member Greg Shinsky takes on the question of Lamba tuning in control loops. Also, don't miss McMillan and Weiner's interview with Hans Baumann, where they ask Baumann about his most notable innovations in control valves.
