Setting up data server tags
To use data server tags, such as those found in Logix5000 and other OPC-compliant
devices, you can refer directly to the tag’s location wherever the tag data is needed.
These are the basic tasks involved in setting up data server tags for an application:
1. Create the tag in the OPC server or processor, or use an existing tag in the processor.
For information about creating tags:
 In OPC-DA servers that have their own tag database, see the documentation
provided with the OPC-DA server.
 In a Logix5000 controller, see the programming software documentation for the
controller.
2. In FactoryTalk View Studio, in the Explorer window, if it doesn’t have a data server,
add one to the application, .
3. Connect application components to the data server tags, wherever the application
needs to use the tag values.
For example, in a FactoryTalk View SE graphic display, connect the animation of a
graphic object to a data server tag. At run time, tag values are passed to the object,
changing its appearance as the value changes.
Setting up HMI tags
To use tags stored in an HMI server’s tag database, connect the tags to addresses in
network devices, and then refer to the HMI tags wherever the tag data is needed.
These are the basic tasks involved in setting up HMI tags for an application:
1. In FactoryTalk View Studio, in the Explorer window, if it doesn’t have an HMI server,
add one to the application. Each HMI server contains one tag database.
2. In the Tags editor, create HMI device tags by mapping tag names to data server or
DDE addresses, or create HMI memory tags. For details, see “Creating, modifying,
and deleting HMI tags” on page 10-21.
3. Connect application components to the HMI tags, wherever the application needs to
use the tag values.
For example, in a FactoryTalk View SE graphic display, connect a numeric input
object to an HMI tag. At run time, tag values are passed to the object and the operator
can read from or write to the tag.
