The PublishedDataItemsType ObjectType is a concrete type and can be used directly.

The PublishedData is defined in 6.2.3.7.1. Existing entries in the array can be changed by writing the new settings to the Variable Value. A new Value shall be rejected with Bad_OutOfRange if the array size would be changed. Entries in the array can be added and removed with the Methods AddVariables and RemoveVariables.

The index into the list of entries in the PublishedData has an important role for Subscribers and for configuration tools. It is used as a handle to reference the entry in configuration actions like RemoveVariables or the Value in DataSetMessages received by Subscribers. The index may change after configuration changes. Changes are indicated by the ConfigurationVersion and applications working with the index shall always check the ConfigurationVersion before using the index.
