The typical lives of industrial control systems (ICSs) are measured in decades. Even so, the time comes when reliability and securing replacement parts becomes nearly impossible given the rapid advancement of technology. There is much to plan and do when the time comes to migrate and modernize the control system. In a Chemical Processing article, […]

Looking Beyond PID Tuning Parameters for Control Performance Issues

When a variability problem emerges in a production process, the first suspect is often to look at the tuning of PID [proportional-integral-derivative] loops. While adjustments can be easily made in most automation systems, this is often not the source of the problem. In an ISA Intech article, Know when to look outside the PID tuning, […]

In adhesive production processes, coalescers and separators are used to accelerate the separation of immiscible liquid (completely insoluble) dispersions. I learned about this from Emerson’s Sudhir Jain and Mark Coughran, who shared a recent visit they made with an adhesives producer to address the control performance challenges they faced. They were seeking consulting help to […]

Anyone involved in process control knows the steep learning curve from what is taught in the universities to what is required to safely, reliably and efficiently control an industrial process. Many of the world’s foremost experts steeped in this knowledge have retired or are quickly approaching retirement age. Several years ago, Process Automation Hall of […]

A question on PID control in the Emerson Exchange 365 community reminded me how good some of the free, online learning tools are available for engineers new to our instrumentation and process automation ranks. The question: i have a question about PID, about setpoint for one pid from other pid ,,,is possible that these two […]
