Good Article on Benefits of Control in the Field
Travis Hesketh of Emerson Process Management has written a good article on the benefits of control in the field on the Process and Control News Europe web site. The function block structure, which enables control in the field, has always been one of the key differentiators of FOUNDATION technology. Control in the field allows end users to fix the setpoint closer to the control limit, providing greater energy efficiency and raw material utilization. CIF also provides single loop integrity, so the loss of a control loop does not result in an unplanned shutdown. The loop stands on its own, and can continue to function even if communciations with the system are lost.
