Factory Talk View SE Network Components

What are the components and their purpose in the Factory Talk View System

1) Factory Talk View SE server (Called HMI server) -
Data or services the HMI server provides are HMI tag values, derived tags, command processing, data logging
- HMI tags
- Total data logged tags
- FactoryTalk View SE client sessions

An HMI server is considered to be ready when:
• The server is able to provide project components, such as graphic displays
and macros.
• The server is able to receive and run commands.
• HMI tag services are started and completely initialized.

2) Factory Talk View Network Directory (Network Directory) -
While the Network Directory is unavailable, you cannot modify the structure of
any dependent application. For example, you cannot add areas or servers to the application, create new security accounts, or change system security policies. The Network Directory server cannot be made redundant.

3) Factory Talk View Linx (data server) (called Device Server) (which can also be set up as FactoryTalk Alarms and Events device-based alarm server) - Manages all tags from devices for example, direct alarm instructions from Control Logix PLCs, like Device database
- Device tags per application
- Tags per FactoryTalk Linx data server

4) Factory Talk View SE client - The only HMI interface to visually display or control the data provided by the Factory Talk View SE server

5) FactoryTalk Alarms and Events Tag based alarm Server -
FactoryTalk tag-based alarms
Logix device-based alarms


6) RSLinx Classic server (or some other OPC data server) - For interfacing other third party OPC compliant Devices.

If a network application requires multiple HMI servers, data servers, or alarm
servers, to distribute the load, it is recommended that you install the necessary
software and run the servers on multiple host computers.
