DataObjectNames

Ordered list of ObjectNames of contained SDOs.

Data type: CHARACTER

Notes:

Read and Write.
This property is normally changed through the SBO Instance Property dialog. It should not be changed until after the Objectnames for the SDOs within the SBO have been set.
Used to check whether the value is still valid, which might not be the case if objects have been removed, added, or replaced since the SBO was last saved.
If this list no longer matches the list of contained SDOs, then it is blank and a default list is created again.
