The FactoryTalk Directory centralizes access to application resources and
components, such as graphic displays and tags, for all FactoryTalk products
participating in a control system.
FactoryTalk Network Directory manages network distributed applications. All the
computers in a given network application must point at the same FactoryTalk Network
Directory.
For more information, see Chapter 4, Setting up the FactoryTalk Directory and
Chapter 6, Working with network distributed applications.
 One or more redundant pairs of computers running FactoryTalk View
SE Server
The HMI servers in an application store HMI project components, such as graphic
displays, and serve the components to application clients.
HMI servers also perform alarm detection and historical data management (logging),
and contain a database of tags.
The FactoryTalk View SE Server software must be installed on computers that are to
run HMI servers. For redundant HMI servers, the software must be installed on both
primary and secondary (or backup) HMI server computers.
For more information about redundant HMI servers, see Chapter 14, Setting up
FactoryTalk system availability.
 One or more redundant pairs of computers running FactoryTalk Alarms
and Events Server
 One or more redundant pairs of computers running data servers
Clients communicate through data servers, which provide access to information in
devices and other data servers that comply with the OPC-DA 2.05a specification.
For information about data servers in a FactoryTalk View SE application, see Chapter
9, Setting up communications and Chapter 6, Working with
network distributed applications.
 One or more engineering workstations running FactoryTalk View Studio
FactoryTalk View Studio is configuration software for developing and testing
FactoryTalk View SE applications.
If you use an OPC data server instead of RSLinx Enterprise, it is recommended that you run
the data server on its own, dedicated host computer.
