FactoryTalk Services Platform
The FactoryTalk Services Platform provides a set of common services, such
as diagnostic messages, health monitoring services, and access to real-time
data, for all the FactoryTalk products and applications used in a control
system.
Using services, FactoryTalk products can share and gain simultaneous access
to resources such as tags and graphic displays that you only need to define
once in the system.
The FactoryTalk Services Platform installs behind the scenes during
FactoryTalk View SE installation. Following are the services the platform
provides:
FactoryTalk Directory centralizes access to system resources and
names for all FactoryTalk products and components participating in an
automated control system. The FactoryTalk Network Directory
manages resources for FactoryTalk View SE network applications, and
the FactoryTalk Local Directory manages resources for FactoryTalk
View SE local applications. For more information, see Setting up the
FactoryTalk Directory on page 77.
FactoryTalk Security centralizes user authentication and
authorization at the FactoryTalk Directory. For information about
securing FactoryTalk View SE applications, see Setting up security on
page 85.
FactoryTalk Live Data manages connections between FactoryTalk
products and data servers. For information about data communications
in FactoryTalk View SE applications, see Setting up communications
on page 177.
FactoryTalk Diagnostics collects and provides access to activity,
status, warning, and error messages generated throughout a
FactoryTalk system. For information about diagnostics in FactoryTalk
View SE, see Logging system activity on page 381.
FactoryTalk Administration Console is an optional, stand-alone tool
for developing, managing, and securing multiple applications.
Note: You must use the FactoryTalk Administration Console to
restore FactoryTalk View SE network applications and to set
up computer accounts, if necessary, after upgrading the
FactoryTalk Services Platform. Otherwise, FactoryTalk View
Studio is the configuration software for developing and testing
FactoryTalk View applications.
FactoryTalk services installed with FactoryTalk View SE
The FactoryTalk Services Platform also supports FactoryTalk Alarms and
Events services, and software-based product activation. These services are
40

You can also use FactoryTalk View Studio to set up FactoryTalk Security
services for the applications you develop. For more information, see Setting
up security on page 85.
Note: FactoryTalk View Studio is also the configuration software for
developing FactoryTalk View Machine Edition (ME)
applications. For information about FactoryTalk View ME, see
the
FactoryTalk View Machine Edition User’s Guide
and the
ME Help.
FactoryTalk View SE Client is software for viewing and interacting with
FactoryTalk View SE local station, network station, and network distributed
applications at run time.
FactoryTalk View SE Server, also called the HMI server, stores HMI
project components (for example, graphic displays) and serves them to
clients. The server also contains a database of tags, and performs alarm
detection and historical data logging.
The FactoryTalk View SE Server has no user interface. Once installed, it
runs as a set of
‘headless’ Windows services that supply information to
clients as they request it.
FactoryTalk Alarms and Events installs behind the scenes during
FactoryTalk View SE installation, and provides system-wide alarm
monitoring and control centralized at the FactoryTalk Directory.
For run-time clients to receive FactoryTalk device-based and tag-based alarm
information, you need to set up application servers to support FactoryTalk
Alarms and Events services. For details, see Setting up FactoryTalk alarms
on page 261.
FactoryTalk Activation provides a secure, software-based system for
activating Rockwell Software products and managing software activation
files.
For information about activating FactoryTalk View SE software, see the
FactoryTalk View Site Edition Installation Guide.
FactoryTalk tools and utilities that support the operation of your
FactoryTalk View SE software. For an overview, see Chapter 1 of the
FactoryTalk View Site Edition Installation Guide.
FactoryTalk View SE features
FactoryTalk View SE provides the flexibility and features you need to create
powerful automation systems for your plant or process. For example, you
can:
54
Getting started with FactoryTalk View SE Chapter 1
Rockwell Automation Publication VIEWSE-UM006K-EN-E
29
Create local station applications for parts of the plant or process that
are self-contained, and are not related to other parts of the process.
Create complex applications that mirror the layout of a plant or
process.
A FactoryTalk View SE network distributed application can contain
several servers running on multiple computers, connected over a
network. Multiple client users can connect simultaneously to a network
distributed application.
Open and modify network applications remotely using FactoryTalk
View Studio.
Use the health monitoring and redundancy features built into
FactoryTalk and FactoryTalk View SE to support system availability at
run time.
Use FactoryTalk Security services to centralize the authentication and
authorization of system users at the FactoryTalk Directory.
Create multi-language applications that support switching between up
to 40 different languages at run time. In a network distributed
application, multiple clients can run in different languages
simultaneously.
Modify HMI tag and alarm properties at run time, and have changes
take effect at connected clients, without restarting the clients.
In a redundant network distributed application, changes made at the
primary HMI server can be replicated to the secondary server.
Create a complete alarm monitoring system that includes FactoryTalk
Alarms and Events and HMI tag alarms.
Using FactoryTalk Alarms and Events services, FactoryTalk View SE
applications can subscribe to and display device-based alarms,
programmed directly into Logix5000 controllers.
Customize alarm summaries and banners to provide specific alarm
data, rather than displaying alarms for the entire system.
Create global objects in global object displays, and use copies of these
objects throughout an application. When you modify the original
object, all linked copies are also updated.
Dock selected displays to an edge of the FactoryTalk View SE Client
window so they can be viewed in a fixed position, at all times.
Use the FactoryTalk View SE Client Object Model and VBA to extend
the capabilities of FactoryTalk View SE, and to share and interoperate
with Windows programs such as Microsoft SQL Server and Microsoft
Excel.

Create trends that show process variables plotted against time.
FactoryTalk View SE trends can display real-time or historical data,
with up to 100 pens (tags) in each trend.
Log data simultaneously to the FactoryTalk Diagnostics log and to
remote ODBC (Open Database Connectivity) databases to provide
various records of production data.
The design of the automation and control system you plan to deploy will
determine which FactoryTalk View SE software components to install and
set up on network computers. Where you install the software also depends on
the type of application.
FactoryTalk View Studio Enterprise is the configuration software for
developing and testing FactoryTalk View SE network distributed, network
station, local station, and FactoryTalk View ME applications. The available
applications are shown below.
To develop or run a Network Distributed application, you can install
different combinations of software on each computer, depending on
needs.
To develop or run a Network Station application, you must install all
the necessary software components on one computer (except for data
servers). Network station applications can connect to data servers that
are located on different machines.
To develop or run a Local Station application, you must install all the
necessary software components on one computer (except for OPC data
servers). Local station applications can connect to OPC data servers
that are located on different machines.
To develop or run a View Machine Edition application, see
FactoryTalk View Machine Edition User’s Guide
and ME Help.
