In this paper, we study the applicability of SVG to SCADA (Supervisory Control and Data Acquisition) systems. One of the main purposes of a SCADA application is to provide an operator with the graphical interface needed to monitor and control the production processes in an industrial plant. Currently, most SCADA systems are based on bitmap graphics or proprietary vector formats to build the operator's interface. We investigate here the advantages and some of the emerging technical challenges of using a web standard such as SVG for developing the graphical components of a SCADA system and how to connect these components to the data sources that determine their appearance.
