South African Instrumentation & Control, April 2009 Michael Brown’s Loop Signature column is ending in SA Instrumentation & Control magazine, and he had this to say: “I am still very frustrated by the lack of interest shown by the vast majority of process companies. To date, the only company that I know of that has instituted optimisation as a separate discipline is Sasol…The equipment is getting more and more advanced, but the base layers do not work any better. In my opinion the vast majority of sophisticated control systems like DCSs and PLC/SCADA systems, are, from the control point of view, really being used as man-machine interfaces.”
