What is Supervisory Control (SC)

This chapter presents the development and design of an industrial application based on new technologies and explores the technological dimension of data acquisition, storing, access, and use; the data structure and integration and aggregating values from data necessary for the control of production processes. The demo application presented here was designed according to the Enterprise-Control System Integration Standard (ISA-95) with the goal of maintaining a standard that defines the interface between control functions and other enterprise management and business functions. The component-based object-oriented development concept was implemented in order to utilize advantages provided by creating a complete plant equipment model. The value of semantics was rediscovered in applications, which communicate among their system modules on Simple Object Access Protocol (SOAP), the standard defined by W3C, whose initiative has provided standard semantics markup languages based on XML as well. The data format and the format of standard XML messages that are used in industrial applications are defined by Business To Manufacturing Markup Language (B2MML) as W3C XML Schema for implementation of ISA-95, while offering the framework for project integration, the separation of business processes from manufacturing processes and focusing on functions instead of systems, organizations or individuals themselves.
