The Problem Classic OPC Solved

1 Copyright 2011 Matrikon Inc.

The OPC Concept: Open Connectivity OPC – A Set of Separate Standards• Classic OPC Specifications

– OPC DA – real time– OPC HDA – history

– OPC A&E – events– OPC CMD – programs

– OPC Security– Complex Data

Why OPC Classic Succeeded• Published industrial standards for system interconnectivity• Domain Agnostic Application Interfaces

– Data model agnostic– Stable application interfaces

Where Classic OPC is used today

Taking Stock of OPC Classic

Challenges to Enterprise Integration

Industrial Landscape Shifts…

•Access to Control Data at Control level.

•Limited corporate access or applications.

•Limited users

Industrial Landscape Shifts…

• Embedded OPC for non

Windows devices

• Growing corporate/operational demand for control data

• Improved security necessary• New Industry segments adopting

OPC

The Challenge

• Next Gen OPC requires:– Operating system agnostic

– Industry Domain agnostic– Scalable: embedded to enterprise

– Single interface/unified address space– Communicate data and context

• Secure, Reliable, Interoperable OPC UNIFIED ARCHITECTURE (UA)Next generation Open Connectivity

OPC UA - High Level View• Not “another” super protocol

• Complements existing protocols

• facilitates data connectivity regardless of underlying protocol

Information Model Specifications IEC, ISA, MIMOSA …

•Comprehensive Data Modeling Handles All Data Needs•OPC UA Clients choose appropriate data detail

OPC UA Solves Even More..

OPC Unified Architecture BaseArchitecture • Integration of DA, A&E, HDA, Commands, Complex Data, and

Object Types

Federation• Abstract data/ information from the plant floor, through

information models, and up to enterprise systems

Information Modeling• Development and deployment of standard information models

to address industry domain specifics

OPC Unified Architecture BaseSecurity• Secure-by-default, Encryption, Certificate Handling

Robustness and Reliability• Communication failure recovery• Redundancy

Companion Standards• Industry collaboration (EDDL, FDT, MIMOSA, ADI)

UA Server

Scalability Through Profiles• Facet: an atomic client/server capability

• Profile:• A defined level of minimum set of facets for interoperability• A set of facets and profiles

• Scalability Profiles• Nano Embedded Device Server – Security is NONE only and only basic

binary DA type calls.• Micro Embedded Device Server – Nano with subscription capabilities.• Embedded UA Server – Micro with more subscription options and some

security.• Standard UA Server – A full UA Server with full DA and subscriptions and

all security

UA AddressSpace

• UA Server models information using:• AddressSpace

– Nodes• Variable: DATAITEMTYPE (Classic Item mapping)• References (Relationships between nodes)• Properties (High/Low Ranges)• …

– Views• UA Servers can organize information into defined

groupings for different UA Clients

UA Modeling• Robust data models can be built using nodes

& the relationships between them.

UA Nodes• Single AddressSpace facilitates all UA Specifications

UA Strengths• Scalable• Domain agnostic• Platform and protocol independent

– Not another super protocol– Protocol mapping across domains

• Data models• Security is baked in• Service Oriented Architecture

UA Challenges• OPC Classic

– Great technology– Often poorly implemented/Executed– DCOM OPC UA still has the word OPC

• Education– No one knows what is behind the curtain– Perceived complexity

• End users are not demanding faster adoption

MatrikonOPC can Help• Training (become an expert):

• OPC UA• OPC Implementations

• Services• Architectural assessments• Technology consulting

• Technology• MatrikonOPC Universal Connectivity Server• Adapters• Server Development

Summary • OPC Classic’s success is undeniable• OPC UA provides

– Secure, Robust, Efficient, Scalable – Platform and protocol independent – Rich clients and servers– Evolutionary, not revolutionary

• OPC UA is ready todayNew capabilities for customersNew opportunities for vendors
