An attribute configuration string describes a data reference. The syntax of a configuration string depends on the type of data reference.
The configuration string for string-builder data references can contain substitution parameters. For attribute templates, any configuration string can contain substitution parameters. See List of PI AF substitution parameters.
With PI Builder, you can see attribute configuration strings in a worksheet. For attributes shown in rows, include the AttributeDataReference column. For attributes shown in attribute columns, clear the Show Values in Columns check box (on the PI Builder tab in the Attribute Data References group).
