Control loops, implemented with proportional, integral, or derivative control circuitry and simpler on/off system control points, are utilized within one of three architectures. PLCs, or Programmable Logic Controllers, are used in smaller and simpler applications. They are the oldest of the three technologies and are often programmed with ladder-logic, relay-based tools. DCSs, or Distributed Control Systems, can be used to control an entire, large scale production facility, such as a power plant or refinery. DCSs can control separate PLC systems and have other branches they simultaneously control. SCADA, or Supervisory Control and Data Acquisition, systems are used to control even larger applications, such as a series of power plants connected to a grid or multiple refineries all supplying multiple pipelines.


Course Objectives

"Place a PLC system within the hierarchy of the three types of systems from most to least complex.
Understand how a DCS's ability to have PID controls implemented both within the DCS computer and the local detectors expands the range of applications this architecture can control.
Relate how SCADA architecture is used for the largest control applications."





Quiz Information

You will not be required to pass the knowledge check questions to move on to the next lesson. These will not be counted as a grade, but each question gives you insight into what you should have learned and the sorts of things you'll need to remember moving forward.



The final exam must be passed successfully with 80% or higher in order to receive your certificate of completion.
