7. OPC Unified Architecture
Reasons for developing OPC UA
.NET is introduced onto the market as successor of COM/DCOM
Boundaries of DCOM
OPC-communications beyond firewalls
Platform-independent application of OPC
High-performance OPC-communication via Web Services
Unified data model
Support of complex data structures
Process data communication without loss of data
Better protection from unauthorized data access
Support of method calls

Summary
Goals:
Improvement of Classic OPC standards to meet new requirements
Provide a platform-independent server-client-architecture based on an object- oriented and abstract data model to address new applications
Technical Implementation:
Abstract data and information model
Technology mappings
Object-oriented approach
Large set of services
Different client and server profiles for different requirements
Detailed security concept

12. OPC Unified Architecture
OPC UA and CIM
Important requirements:
Applicable to extended CIM models (because in many cases deployed models include numerous enterprise-specific objects)
Platform-specific model (PSM) as basis:
All CIM-information will be preserved
Stereotypes are used to annotate UA-specific information
Design decisions can be stored and loaded
Handle new versions by difference models
Tool-Support:
Add-In for Sparx Enterprise Architect (the tool which is used to maintain the CIM)
