Seven Ways Today's Distributed Control Systems (DCS) Can Save You 20% or More
White Paper By ABB
In the past, DCS Systems were large, expensive and very complex. This drove many control engineers to use PLCs and HMIs in order to lower cost. Today, these implementations are consistently more expensive than DCS systems for the same process or batch application. This white paper documents the key advantages of DCS systems over PLC/HMI engineered systems and the typical value of each.

Optimizing OPC Communications with Middleware Products
