Manage enumeration sets

Beginning with PI AF 2018 SP2, you can export digital state sets from a Data Archive to create enumeration sets. For more information, see Review digital state sets on a Data Archive.

You use enumeration sets in attribute templates whenever you want to be able to select from lists of predefined values when you are defining element attributes. You also use enumeration sets to create reason attribute traits for event frames and transfers.

In the viewer, right-click an existing value to which you want to add a child enumeration value, and click New Child Enumeration Value.
