In the context of GridWorks, SCADA refers to:
A device, and software, that monitors and controls a TerminalAsset
A GNode representing the above.
SCADA is also a more generalized industry term for any device capable of supervisory control and data acquisition.
The functions of the SCADA are pretty straightforward and obvious, given the goals of transactive energy. A SCADA needs to:
Sense and report information relevant to the performance of the TerminalAsset, including but not limited to the power and energy metering;
Let its AtomicTNode call the shots on how the TerminalAsset uses (or provides) electrical power, whenever the two are communicating; and
Do a decent job of running the TerminalAsset on its own when it loses communications with its AtomicTNode.
