The Benefits of an Open Process Interface


What is OPC ?

Industry standard OLE (COM) interface for data transfer between industrial clients and servers.

OPC Foundation established in 1996.– International Non-Profit Foundation established for enacting

the specification of the OPC interface. (Membership of the OPC Foundation is now over 350)

– Working as a member of committees for OPC specification.

Yokogawa has been a member of the OPC Foundation since it was established in 1996

OPC = OLE (Object Linking & Embedding) for Process Control

OPC = Openness, Productivity, Connectivity

Object-oriented system provides standard framework for the configuration of reusable software components in Windows environment.

OPC interface OPC interface

• No single standard for interfacing with process data sources.

• Application vendors must each develop proprietary interface.

• Provides a standard interface for applications to communicate.

• Vendors only need to adhere to the standard OPC interface.

• Reduced cost• Investment

protection• Easier to maintain• Increased

productivity


Features of OPC

Connectivity & Flexibility– Multi-vendor supported client-server architecture– Easy access to real-time industrial data from a

broad range of automation devices and systems

Efficiency– optimized for the process industry for fast data transfers

Expandability– Continuous evolution of specification

standards in line with technology breaks


Merits of OPC

End User– Broad range of vendor selection providing more

flexible system integration at reduced cost– Reduced total cost of ownership

Application Engineer– Availability of a general-purpose integration tool– Eliminates need for bespoke interface

development

Software Developer– Unification of device driver development– High level of code reusability in

extension of interface libraries


Data Access (DA) interface– Reads & Writes real-time process data

Alarms & Events (A&E) interface– Notifies on Alarms and Events occurring asynchronously from

process fields

Historical Data Access (HDA) interface– Reads time-sequential process data (Historian, Trend data)

Batch Data Access interface– Exchanges Batch data (ANSI/ISA-S88.01)

• Equipment capabilities• Current operating conditions• Historical data• Recipe contents

OPC Specifications -1


Security (enhanced)– Common OPC interface for Security issues in accessing O

PC servers of DA, A&E, HDA and others

OPC-XML (under discussion)– Data exchange using XML format

OPC-DX (under discussion)– enhanced communication for multi-server and multi-vend

or integration

OPC Specifications -2


Yokogawa Role Within The Foundation

Member of the ‘Council’ in Japan– Specification definition and enhancement– Review of technical impact of recommendations

Product Development in Support of the Foundations Objectives– Exaopc Server– All application products offer OPC Client capability : Exaquantum, Exa

smoc, Exaspot, Exaplog, Exapilot etc..– Currently developing OPC Server capability for Exaquantum

What is Exaopc

Highest Performance Highest communication performance <2,000data/sec.>

Reliability & High Quality DCS class quality Online configuration History catch-up

Connectivity Full compliance to OPC standard interface, and one of the

best interoperability Server with OPC client

plus valuable functions


Over 7800 OPC servers are installed in the

world

Exaopc Primary Features

Reliability History Catch-Up : Automatic back-up of historical data Traffic Stability : Cut off limits for peak access

Easy Engineering DCS Tag List Equalization : Automatic equalize of tags Connection Test Tool : Analysis and trouble shooting

Yokogawa DCS customization Message integration with HIS operator’s station

(Process Alarm / Sequence Message / Operation-Guide etc.)


Automatic back-up historical data– Automatically saves process data acquired by DA

Server for a defined period.– Restores data on restarting, even if the client is

down.– Facilitates reference of time

series data.– Unnecessary for client

to specify data saving.(2)Client re-start

Data Buffer

(3)Catch Up

Increased reliability of data.

History Catch-up

OPC Client(1)Client stop


Peak access management– Controls influence of massive data access from

client over DCS system functions– Avoids control station and control bus data access

overload– Orders client to standby when exceeding max

number of accessible data items

Optimized data handling to improve overall system

efficiency

Traffic Management


Automatic equalization with DCS tags– Acquires CENTUM tag listing on Exaopc– Auto-notifies the client of addition & deletion of

tags occurred within the CENTUM domain– Updates internal table for data acquisition based

on the notified information and informs OPC client of the update

Simplifies engineering to reduce deployment costs

Analysis and trouble shooting

– Integration test with DCS is possible without OPC client.

– Reduces maintenance man-hours when investigating communication errors.

The engineering efficiency improves

rapidly.
