An operator monitors a sprawling pipeline that stretches across several hundred kilometers, with unmanned pumping stations reporting back to a central control room over leased lines and radio links. Which class of control system is purpose-built for this kind of widely dispersed, telemetry-driven supervision?
- A.Standalone PLC
- B.DCS
- C.SCADA
- D.Safety instrumented system
Why C is correct
SCADA (Supervisory Control and Data Acquisition) is optimized for geographically dispersed assets where data is gathered from remote sites over wide-area communications. A DCS, by contrast, is tuned for a single plant or process within one facility.
