Distributed Control System Components

 This lesson lists the components associated with a common DCS and describes its functions. • List and briefly describe plant instrumentation used to collect system parameter and equipment data to use in a DCS • Describe the general design and function of the following DCS components: – Instrumentation – Transmitters and input/output modules – Processors – Multiplexers – Electrical/computer buses – Human-machine interface – Control devices/actuators • Discuss the flow of information through the DCS and describe how that information is used to monitor and control power plant systems, parameters, and equipment
