Extending OPC-UA through Architecture Flexibility, Performance, and Scalability

Building Large, Disparate Systems

Dave ScheibenhofferReal-Time Innovations

Industry Checkpoint

Collaboration

Business Centric DecadeShift from enabling technology

to using

Available and proven Technologyto improve Business Performance

Operational Efficiency

• Business Goals– Return on Assets– Continuous Improvement– Flawless Execution– Automate– Total Cost of Ownership– Common Infrastructure– Barriers to Information

• Business Benefits– Operational Effectiveness– Asset Utilization– Minimize Variable Costs– Reduce Downtime– Preserve Capital Assets

Business Centric

System Requirements

• Collaborative Automation Systems– Guiding Principles

• Extensible• Common Data Model• Adaptable through Configuration• Single Version of the Truth• Interoperable• Standards Adoption• Multi-supplier Support• Security and Reliability• Actionable Context Support• Knowledge Workplace Support

Problem Statement

The Systems Engineering Challenge

• Systems – Built from components

• System of Systems – Convergence of disparate systems

• Small Systems– Integration is challenging

• Large Systems– Integration costs dominate

System Scale

Must ease integration complexity

Four Key Factors in Distributing Data

• Number of Devices– Ever expanding and many disparate types

• Volume of Information– Only send pertinent data

• Density of Pipe– Limited bandwidth which must be used wisely

• Timeliness– Making data available when it is needed

Need for Scalability, Reliability, Performance

Combination of Both

Workflow-Driven Services•IT systems respond to human intention on demand

•Focus on access to stored data•Consistency is mission-critical

Event-Driven Services•Detect change and respond automatically•Focus on processing data as it changes•Availability is mission-critical
