Increasing Project Efficiencies in Control System Modernizations

Jim Cahill

As members of the “baby boom” generation retire and remove their deep experience from process manufacturers and producers, sometimes the remaining staff knows little of the inner workings of the control systems. Many of these distributed control systems and PLCs that have been in service for decades have become “ black boxes ” in which the current staff is fearful to touch. There is a need to modernize these systems…
