SCADA, communications, and controls are the pipeline’s nerves providing multiple inputs from the pipeline and carrying back control commands.  From field instruments, station PLCs or computers, to the control room computers and operator consoles, this module provides a broad overview of the entire control scheme from a practical perspective.  Students find the scada video particularly interesting.

Learning Objectives

  • Describe the major scada components.

  • Explain the difference between local station and centralized scada.

  • Explain the purpose of a “smart device”.

  • List at least three design decisions.

  • Describe what scada applications are.

  • Describe what “time stamped” means.

  • Explain what “process data” means.

  • Explain what an “event” is.

  • Explain what a “command” is.

  • Describe the types of information contained in the “real time data base”.
