FactoryTalk Directory

FactoryTalk Directory
 enables the parts of an application to locate each other on a computer or on the network.
FactoryTalk Security
 provides security for the resources managed by
FactoryTalk Directory
. You can set up
FactoryTalk Security
 to restrict such things as who can open, modify, and delete an application or area, and who has access to the
FactoryTalk Directory
 from which computers. For example, to access graphic displays on an HMI server in the application, HMI clients use
FactoryTalk Directory
 to find out which computer on the network is hosting the HMI server.
FactoryTalk Directory
 also stores the information about which users and computers are allowed access to the various parts of a control system if you have used FactoryTalk Security, to secure access to the resources that
FactoryTalk Directory
 manages.
In a network system, if
FactoryTalk Directory
 becomes unavailable while an application is running, the application will continue to run correctly. For example, the
FactoryTalk View SE
 client will be able to read and write values, acknowledge alarms, and open and close displays because a copy of the information provided by
FactoryTalk Directory
 is stored locally on each computer that is connected to the
FactoryTalk Directory
 computer. However, while
FactoryTalk Directory
 is unavailable, you cannot modify an application's structure; for example, you cannot add or edit an area, a data server, or an HMI server.
If you are installing
FactoryTalk Services Platform
 on a computer for the first time with the standard FactoryTalk Directory mode:
  • In the
    FactoryTalk
     Local Directory, all users have full access to the directory and to
    FactoryTalk View
    .
  • In the
    FactoryTalk
     Network Directory, all users that are members of the
    Windows Administrator
     group on any local computer that is connected to the
    FactoryTalk
     Network Directory, will have full access to the directory and to
    FactoryTalk View
    .
If you are upgrading an existing
FactoryTalk
 system that is earlier than version 5.10, whatever security you previously set up will continue to be in effect.
When you create a
FactoryTalk View SE
 application, the user groups
Windows Administrators
 and
Administrators
are created in the
FactoryTalk Directory
. Also, the group account
All Users
 is added automatically to the FactoryTalk View Runtime Security accounts. By default, the
All Users
 group is granted all
FactoryTalk View SE
 runtime security codes (A - P), and all
FactoryTalk Security
 actions at the root directory node.
TIP:
The
FactoryTalk Directory
 server must not be installed on the same computer as the domain controller for the network.
All the computers participating in a distributed application share a common
FactoryTalk Directory
 located on a network computer.
