Use parameters and global objects
This chapter describes:
 Use tag placeholders and parameter files or lists.
 Create tag placeholders.
 Create parameter files and parameter lists.
 Use global objects.
 Create global object displays and base objects.
 Create, set up, and delete reference objects.
 Use global object parameters.
 Adding controller instruction faceplates that connect to Logix5000 processors.
The topics in this chapter describe features of FactoryTalk View Studio that can help you
set up your applications more quickly by reusing similar groups of objects and graphic
displays.
 Tag placeholders, parameter lists, and parameter files allow you to use the same
graphic display with different sets of tags.
 Global objects allow you to use multiple instances of the same graphic object and
make changes to all of the objects at once.
 Global object parameters allow you to assign different sets of tags to different copies
of the object without breaking the link to the base object, thus preserving the ability to
update all copies of the object at once.
 Controller instruction faceplates provide pre-configured graphic displays that interact
with the instructions in Logix5000 processors.
Use tag placeholders
Use a tag placeholder to mark where you want to insert a tag name or some part of a tag
name at run time. A tag placeholder is a crosshatch character (#) followed by a number
from 1 to 500.
FactoryTalk View Machine Edition uses three methods for replacing a tag placeholder
with a tag name:
 Parameter files
 Parameter lists
