Problem Statement: Users/Apps Can’t Easily Access Integration Bus Data Energy Management Systems Outage Management Systems Supervisory Control and Data Acquisition Asset Management System EMS OMS SCADA AMS 61968-100 Integration Bus DMS CIS MDMS Distribution Management Systems Customer Information System Meter Data Management System

Huge Data Not Possible For An Individual or Application To Receive And Process All Integration Bus Messages. Users need a way to find and filter data Inte gra tion Bus sag es Mes

Example: Meter Readings via IEC 61968 Part 9 Messaging A meter reading head end may send out a million meter events a day. Each meter is typically identified by a numeric ID. IEC 61968 Part 9 messaging supports getting a list of every meter ID and to poll for specific meter events once you have the meter ID. How does a user who is only interested in VIP metering events select the data of interest? Is it possible for any human to go through a million numeric IDs to find the ones of interest?

IEC 61968-100 Smart Proxies IEC 61968-100 states that “smart proxies” can be used to implement topic based subscriptions but does not specify how this is done. OPC UA can be used to create a “smart proxy” with additional features for intermittently connected clients.

Typical Approach: Warehouse Based Portal Putting all messages into a data warehouse disables real-time eventing. The portal typically has no means to notify applications/users that new data of interest is available. Using a data warehouse/portal in this way supports query, but defeats the purpose of an event driven architecture which is one of the main goals of an integration bus HTTP Server Pre- Configured Web Portal IEC 61968 - 100 Integration Bus Data Warehouse

CIGRE D2.24 Utility Information Architecture Specifies QCRUD Access to Current/Historical and Model/Measurements: Query, Create, Update Delete

Using Web Services Gateway to Access Operational Data Gateway supports unified QCRUD access to Integration Bus and Data Warehouse IEC 61968 - 100 Integration Bus Data Warehouse Gateway supports QCRUD: Client Query and Topic based Message Subscription all configured via a model driven GUI. Need services that are not tied to the database layout of the database, instead data is access via CIM objects.

User only receives messages of interest base on topic and content OPC UA Can Be Used To Provide QCRUD Access To Integration Bus Data User only receives messages of interest base on topic and content OPC UA Client OPC UA Gateway with IEC 61969 Message Adapter OPC UA Adapter can send and receive IEC 61968 Part 9 messages IEC 61968 Part 9 message payload in OPC UA WS Event Integration Bus IEC 61968 Application IEC 61968 Part 9 Messages in IEC 61968-100 WS Event IEC 61968 Application IEC 61968 compliant applications exchange IEC 61968 Part 9 messages according to IEC 61968-100 architecture over integration bus

Why Use OPC UA OPC UA is becoming the defacto standard for model based Web Services in the process control industries Support growing fast by tool and application vendors Unique capabilities include: Address Space Model Full Mesh Supports versioning of type information and instance data Eventing to support WG 14 messages Security Performance Availability and Reliability Established testing procedures, tools and organization Backward compatible with OPC DA COM means that migration and interoperability issues are greatly diminished
