distributed applications on page 125. Local station applications are described
in Working with local station applications on page 167.
Parts of a network station application
A typical FactoryTalk View SE network station application consists of:
One or more areas that divide the application into manageable parts or
organize it in a way that makes sense for the process it is controlling.
Keep in mind that only one HMI Server can be added to a FactoryTalk
View SE network station application.
An HMI server that provides FactoryTalk View components and
services to application clients. A network station application can
contain only one HMI server.
HMI project components such as graphic displays, HMI tags, and data
One or more data servers, providing clients with access to information
in programmable controllers, devices, and other data servers that
comply with the OPC-DA 2.05a specification, with or without the use
of HMI tags.
In a network station application, you can use multiple RSLinx
Enterprise and OPC data servers (including RSLinx Classic), running
on different computers. You can also set up a redundant pair of host
computers for each data server in the application.
RSLinx Enterprise servers can be set up to subscribe to device-based
alarms detected in Logix5000 controllers. For more information, see
Setting up FactoryTalk alarms on page 261.
s OPC data server is different. Some
contain their own tag databases, like the tag database in
an HMI server, while others reference the tag databases
or addresses that exist in controllers, as is the case with
RSLinx and RSLogix.
A list of users, plus the security codes that allow or deny these users
permission to access secured HMI project components at run time.
Optionally, one or more FactoryTalk Tag Alarm and Event Servers, to
provide alarm monitoring and control for tags in devices that do not
have built-in alarm detection. For more information, see Setting up
FactoryTalk alarms on page 261.
The HMI server and the HMI client are the software programs behind a
network station application that must be located on the same computer. The
FactoryTalk Directory Server, the RSLinx Enterprise data server, and the
OPC data servers can be located on remote computers.
