If the data type of the attribute is Then
One element (for example, DINT) Create a tag for the attribute.
More than one element (for example, DINT[7]) − Create a user-defined data type that matches the
organization of data that is used by the attribute.
− Create a tag for the attribute and use the data type
that you identified for the object.
