Development of service oriented web-based SCADA application

Abstract

This paper presents some considerations on the development and use of Web services in Web-based SCADA applications . SCADA systems are becoming more and more comon allowing the user to monitor and control local and remote technological processes. SCADA Web-based applications are SCADA applications for web clients, that run in web browsers. The use of Web services enables the development of web SCADA applications in a consistent way, by using the standardized methods for data transmission. Web services use XML standard for data transfer. This paper also proposes the use of the XML standard for describing virtual instruments.
