OPC UA Based Information Modeling for Distributed Industrial Systems

Data representation in devices of industrial systems is simple data However, the structurial data organization is used in impel layers of such systems This information can be modeled by vendors, which of course would lead to different ways of how to model similar lamination thus makes the life Mad for clients, e g OPC clients There ale efforts to define a base model to expose device information and device types A vendor will use this base model and extend it with vendor-specific information thou! its devices This paper introduces an object-oriented data model based on the OPC Unified Architecture (UA) specifications and Unified Modeling Language (UML) used for communication in distributed industrial systems This model is applied for device and information models to provide data for enterprise systems
