When you use a name substitution, a direct substitution of the substitution parameter for whatever that particular parameter represents is made.
The table in List of PI AF substitution parameters lists the available substitution parameters and what they represent. For example, is a substitution parameter that represents the element name. After you create an element based on that template, you tell PI AF to create the data reference (Attribute-value updates from PI point data references). When PI AF creates the reference, it substitutes the current element name wherever the configuration says .
Suppose you have a data reference template that references the PI point name:
%Element%_TT
You create an element named Tank1 that is based on that template. The attribute data reference points to a PI point named:
Tank1_TT
