
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


5
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
Grid
Cloud
System
s

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

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

Backward compatible with OPC DA COM means that migration and
interoperability issues are greatly diminished
