Advantages of DBs with an Assigned UDT
By using UDTs you have created once, you can generate a large number of data blocks with the
same data structure. You can then use these data blocks to enter different actual values for
specific tasks.
If, for example, you structure a UDT for a formula (for example, for blending colors), you can assign
this UDT to several DBs each containing different amounts.
The structure of the data block is determined by the UDT assigned to it.
