FactoryTalk Security
The FactoryTalk Local Directory can use FactoryTalk Security services to authenticate
and authorize users of FactoryTalk View SE local station applications.
During FactoryTalk View SE installation, Windows users with administrative privileges
on the computer are set up with full, initial access to FactoryTalk View SE applications
managed by a FactoryTalk Local or Network Directory on the same computer.
In FactoryTalk View Studio, you can create FactoryTalk user and group accounts, and
then determine which accounts have access to resources such as the Local Directory, or
the application.
For an overview of FactoryTalk Security services, see Chapter 5, Setting up security. For
details, see the FactoryTalk Security Help.
About FactoryTalk Security permissions
If FactoryTalk Security services are used to secure parts of an application, to perform
certain tasks, users must have the necessary security permissions.
For example, to create or modify the properties of an application, you must at least be
allowed the Common actions Read, List Children, Write, and Create Children, at the
FactoryTalk Directory that manages the application.
If you receive a FactoryTalk Security message while trying to perform such a task, contact
your system administrator about permissions you might require.
HMI servers
HMI servers are software programs that supply information to clients as they request it.
An HMI server stores HMI project components such as graphic displays, and serves these
components to clients. An HMI server also manages a database of tags, detects HMI tag
alarms, and logs historical data.
In FactoryTalk View Studio, when you create a local station application, the HMI server is
created automatically, and given the same name as the application.
A local station application can only contain a single HMI server.
Do not run FactoryTalk Directory, or any other application software, on the same computer as a
Windows domain controller.
