What's a FactoryTalk Directory
The FactoryTalk Directory references tags, data servers, security settings,
and other project information from multiple data sources, and then makes
this information available through a lookup service to all software products
participating in that FactoryTalk system.
For example, tags are stored in their original environments, such as logic
controllers, and graphic displays are stored in the HMI servers where they are
created. Yet all of this information is available, without duplication, to any
FactoryTalk product participating in the FactoryTalk Directory.
The FactoryTalk Directory can be either a Local Directory or a Network
Directory. See Understanding FactoryTalk Directories on page 262 for more
information.

FactoryTalk system
You can create a FactoryTalk system that suits the needs of your facility. For

Platform, FactoryTalk View, RSLinx Classic, and RSLogix 5 all installed on
the same computer, communicating with a single programmable logic
controller, and all participating in the same Local Application held in a Local
Directory.
Or a FactoryTalk system may be much more complex, with software
products and hardware devices participating in multiple Network
