You can also use one or more tag placeholders to specify parts of a complete tag name.
In #1\PV, for example, the tag placeholder #1 stands for the name of the folder that
contains an HMI tag named PV.
To specify the full tag name at run time, you would only have to provide the folder name
in a parameter file or parameter list.
Replacing tag placeholders using parameter files
One way to replace tag placeholders in a graphic display with actual names at run time is
to load a parameter file with the display.
The parameter file should contain one entry for each unique tag placeholder in the display.
For example, to replace #1 with a tag named corn/weight, you would create a parameter
file that specifies #1 = corn\weight.
Loading a parameter file with the initial client display
You can specify a parameter file to load with the graphic display that opens initially, when
the FactoryTalk View SE Client starts up.
To do this, in the FactoryTalk View SE Client Wizard, select the display in the Initial
display list. Then, in the Display parameters box, type /P followed by the name of the
parameter file to load with the display (for example, /PBeans).
Example: Replacing tag placeholders using a parameter file
To open a graphic display named Canning and replace tag placeholders in the display with
the names specified in a parameter file named Beans, you would issue this command:
Display Canning/PBeans
You can use wildcard characters in a parameter file entry only if the tag placeholder to be
replaced is specified for an HMI tag alarm summary. In that case, a parameter file containing the
entry #1 = bean_* would specify alarms associated with all tags beginning with bean_ .
