Supervisory control and data acquisition (SCADA) is a system for remote monitoring and control that operates with coded signals over communication channels (using typically one communication channel per remote station).
In terms of applications, DCS is the system of choice for installations that are limited to a small locate, like a single factory or plant, while SCADA is preferred when the entire system is spread across a much larger geographic location,like a power station or oil wells which are spreaded out in a large field.
