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.
In PI System Explorer, when you select an attribute with a data reference, the configuration string appears in the text box below the Settings button. You edit configuration strings directly in the text box.
The following table contains examples of configuration strings for different types of data references:
