Introduction to Unified ArchitectureThe Next Generation of System Interoperability
Thomas J. Burke
OPC Foundation President & Executive Director
Thomas J. Burke 2
OPC Foundation’s New OpportunityImprove the Existing … and … Find Its Place in …
Next Gen Systems: Enterprise InteroperabilityMany complex information structures
Many groups working on semantics: schemas+
Complex exchanges between platformsBusiness & Integration processes (scenarios)
Consolidation of standards – less overlap
Reduce complexity, easier decisions, …Faster progress
New architecture with bigger scope:Service-based (SOA, SBA, …)
Scope includes other platforms:Microsoft, Oracle, SAP, IBM, …

Enterprise Interoperability Fundamentals
Existing OPC Interfaces within new capabilities …Component-based information modeling
Operations Application must have Flexible Asset and Resource Modeling
Accommodate many semantic standardsISA/B2MML, OAGi, RosettaNet, CIDX, …
Support standard messaging (above)Support reliable enterprise-wide orchestration
Within Enterprise and Operations Platform ToolsStrong security integrated with infrastructure
Better management of security information
Thomas J. Burke 8
Where Does OPC UA Help?(Definitely a work in progress)
(Does not specify user data management, …)Encryption, Digital Signatures, PKIWeb Service Security StandardsTraceability & Audit Records required
Security
(Does not address orchestration)… Exposes common services (for Orchestration)… Exposes Standardized Programming I/F’s… Provides common state model for managing services
Unified Orchestration
(Does define or address messaging)Complements Industry Standards Create and expose Object Commands (Methods and Programs)
Unified Messaging
(Does define semantics or address mapping to Apps)Complements Industry StandardsCreate and Expose Object Structures
Unified Semantics
(Does not define data models)Provides Common Object Management MethodsSupports more complex and flexible models
Unified Data Models
Existing OPC I/F’s …Subscription Model
Support Legacy Systems

How is OPC UA Going to Work?Use UA-Based Software Supplier Platforms and Tools
Communications
ContextViews &Concepts
Unified Information& Events
Unified Processes &Workflow
Provide Tools to “Import” Industry Standards into UA and Create Shared UA Objects and Commands
Provide Tools to Create andExpose Application Object Info and Commands
as UA Services and Programming I/Fs
Use Platform Tools (Portal, UI, …) to Create Role-Based Common Views by
Browsing and AccessingShared UA Objects and Commands
Use Platform Tools (BPM, EAI, …) toCreate Processes and Mappings by
Browsing and AccessingShared UA Objects and Commands
OPC UA Server Suppliers
OPC UA Client Suppliers
“Conform to UA Security Guidelines”
Thomas J. Burke 10
Questions:Once we Understand …
Explore the Implementation of UAHow will Commands get created?
How will industry standards (semantics, messages, …) be used on OPC UA?How do we expect Enterprise Apps to use OPC UA?
What do we expect suppliers to implement?
Will OPC Foundation manage any shared code?
Who is working on UA and what are their deliverables?How can we become more aware of its status and monitor its progress?
(If we run out of important things to talk about)OPC UA talks about Objects - How does OPC UA compare to CORBA?

COM object
Interfaces
ServerClient
Pointers tointerfaces
A client accesses a COM object's services through pointers to its interfaces.
Function1( )Function2( )Function3( )
Each interface provides one or morefunctions
An interface is a collection of methods or related functions and procedures that perform some specific service that the COM object will provide.
COM does not specify the implementation of interfaces, only their behavior in interacting with clients.
