What is SCADA and how does it relate to BAS?

• A. Supervisory Control and Data Acquisition; a system for remote monitoring and control
• B. System Control and Data Analytics; a local-only control system
• C. Standardized Calibration and Data Aggregation; a device protocol
• D. Sequence Control and Data Access; a field device interface

Answer: (A)

SCADA stands for Supervisory Control and Data Acquisition, a system designed for remote monitoring and control of processes from a central location. In building automation, SCADA provides the supervisory layer: it collects data from field devices like sensors and actuators through controllers, presents dashboards, logs trends, raises alarms, and sends control commands to equipment. This lets operators oversee and adjust building systems—such as HVAC, lighting, and pumps—from a single interface, even across multiple zones or sites. The relationship to BAS is that BAS can use SCADA software as the central supervisory framework, enabling centralized visibility and control. SCADA emphasizes remote data gathering and control over distances, while BAS covers broader automation within buildings. The other descriptions don’t fit the standard term: they describe an invented acronym or a function that isn’t what SCADA represents.
