Create parameter files
The parameter file specifies which tags to substitute for the placeholders in the display, by
assigning one tag to each unique placeholder in the display. Create a parameter file for
each set of tags that you want to use with the same graphic display.
At run time, the tag values that are shown depend on which parameter file is used when
the display opens. When you open the display, the tags specified in the parameter file
replace the tag placeholders.
Parameters can replace any portion of a tag address. For example, you can use parameters
to replace folder names.
Parameter files can list up to 500 tag placeholders. Use them when a large number of tag
placeholders are needed for a display. The text format of a parameter file allows you to see
and edit the placeholders easily. When copying displays from one application to another,
the related parameter files must also be copied.
