Display content – part 2

A mistake often made with operator displays is to limit the scope of the design work to mimic the process equipment shown on P&IDs and Process Flow Diagrams (PFDs). These initial displays include measurements, valves and final control elements. They include enough of the process equipment and piping so that the process flow can be …

DeltaV Mobile

In process manufacturing the operator station allows operators to rapidly assess a set of distinct systems or situations under their span-of-responsibility and determine where attention is needed on a moment-by-moment basis. If a problem exists, the features of the operator station directs the operators to displays from which they can troubleshoot and take action. So …
