A conceptual model for distributed systems of data acquisition and control

Abstract

The Supervisory Control and Data Acquisition (SCADA) is one of components of hierarchical control systems. This article focuses on offering a conceptual model for distributed systems of data acquisition and control on the basis of functional estimations, structural, advantageous and disadvantageous analyses of SCADA systems existing in industrial automation. The behavior and the interaction between components in the model are also described. Lastly, the open features of offered model in the article are listed.
