Example: Configuration and data flow for the station with remote OPC UA Server architecture

A station architecture hosts the

FactoryTalk

client,

FactoryTalk

Network Directory server, and

FactoryTalk Linx

OPC

UA Connector on a single workstation. A remote computer or embedded device might provide the OPC UA Server.

Software	Installed on Computer	Configured Using
FactoryTalk client, FactoryTalk View SE	WKSTN1	FactoryTalk View Studio

FactoryTalk Linx OPC UA Connector server and endpoint selection settings configured using Explorer FactoryTalk Linx OPC UA Connector OPC UA Servers .

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.
