Example: Configuration and data flow for complex distributed architecture

A distributed architecture hosts the

FactoryTalk

clients,

FactoryTalk Services Platform

instances,

FactoryTalk

Network Directory server,

FactoryTalk Linx

OPC

UA Connectors, and

OPC

UA Servers on separate computers. The following distributed architecture has two

FactoryTalk Linx

OPC

UA Connectors and three

OPC

UA Servers. A real-world architecture might consist of dozens of

FactoryTalk Linx

OPC

UA Connectors and

OPC

UA Servers.

Software	Installed on Computer	Configured Using
FactoryTalk client, FactoryTalk View SE	WKSTN1	FactoryTalk View Studio
FactoryTalk Services Platform configured as FactoryTalk Network Directory server	FTDSVR1	FactoryTalk Administration Console
FactoryTalk Services Platform configured as client	WKSTN1, CNSRV1, CNSRV2	FactoryTalk Administration Console
FactoryTalk Linx OPC UA Connector	CNSVR1, CNSVR2	FactoryTalk Linx OPC UA Connector settings configured using Explorer FactoryTalk Linx OPC UA Connector Connector Settings . FactoryTalk Linx OPC UA Connector server and endpoint selection settings configured using Explorer FactoryTalk Linx OPC UA Connector OPC UA Servers .
OPC UA Server	OPCSVR1, OPCSVR2, OPCSVR3	Software provided by OPC UA Server

When a

FactoryTalk

client, such as

FactoryTalk View SE

, requests a tag provided by

FactoryTalk Services Platform

, the

FactoryTalk Linx

OPC

UA Connector subscribes to the

OPC

UA Server node. When the node value is received, the

FactoryTalk Linx

OPC

UA Connector provides the value to

FactoryTalk Services Platform

as a tag, which the

FactoryTalk Services Platform

service returns to the

FactoryTalk

Client.
