SCADA systems are combinations of field devices, communications infrastructure, computer hardware and software integrated into a system that provides for safe, reliable, and effective operation of remote facilities. Producers, gatherers, midstream operators and pipelines use SCADA system for operations. In addition, SCADA gathers data used by advanced applications such as measurement accounting. SCADA is key for highly profitable operation.
This paper provides and overview of the building blocks of the SCADA system. The SCADA host and advanced applications are discussed in detail. The paper concludes with a discussion of SCADA trends.
