In this video, Zahraa Khalil explains what supervisory control and data acquisition, or SCADA, is within industrial automation systems and the definition and role SCADA plays in current industries.
- [Instructor] SCADA. SCADA is an acronym for supervisory control and data acquisition. The major function of SCADA is for acquiring data from remote devices, such as valves, pumps, transmitters, et cetera, and providing an overall control remotely from a SCADA host software platform. This provides process control locally so that theses devices turn on and off at the right time and a remote method for capturing data and events for monitoring these processes.
SCADA host platforms also provide function for graphical displays, alarming, trending and historical storage of data. A typical SCADA system consists of SCADA master that is connected to either a remote location unit that contains controllers, remote terminal units or PLCs or connected locally to a local location unit that is connected to a control system. It could be either a PLC or DCS and off field devices.
SCADA was traditionally used for data collection from PLC and floor controllers. SCADA systems were used for monitoring and supervisory control for processes. The role of SCADA now expanded. They are a vital part of many manufacturer information systems. They provide manufacturing data to many other software systems in a typical manufacturing settings.
Learn about the components and networks involved at each level of automation: field level, control level, and management level. Explore the different devices involved, from the programmable logic controllers (PLCs) on the factory floor, to OPC software that give technicians insights into operations. Instructor Zahraa Khalil, an engineer and educator, also provides an overview of SCADA (supervisory control and data acquisition), an industrial control system architecture that enables supervision over large distances and multiple sites.
