DCS vs. PLC: Selecting the Right Platform for Your Application

Despite much of the argument that has persisted through the years, distributed control systems (DCSs) and programmable logic controllers (PLCs) are not mutually exclusive technologies. When the end-use application serves as the basis for making a sound decision, the selection process becomes more efficient, and a more effective outcome results. This white paper provides general guidelines and highlights key considerations when choosing a control system platform. While the details of each application are critical to the selection process, use the 8-page white paper as a guide when designing, specifying, and implementing controller technology. The paper includes a comparison chart and block diagrams.
