Abstract

This  paper, titled,  “Overview of the Supervisory Control and Data Acquisition (SCADA) System ” is a precursor to the subsequent p apers on  analytical performance model for SCADA System protocols. We examine the fundamental functions expected from a SCADA System, its components  and the distinct features between SCADA System and Distributed Control System (DCS)  – both are members of the set of Indus trial Control System  (ICS). This work is quite different from others as SCADA System is considered from different perspectives such as : a) role in monitoring and control of  critical infrastructure  like national electricity supply system and oil and gas pipelines; b) its layout and hierarchical architecture and c) its Master/Rem ote  Terminal Unit (RTU) functional data/control flow. Its hierarchical model presented is compared with the Purdue Enterprise ref erence Architecture (P E- RA) which is one of the general models that visualize the entire enterprise system from the field or the  plant to the apex (Computer System or produc- tion Scheduling). Compliance is confirmed
