So I have 5, 2-dimensional Arrays, they are [61,22], in my CompactLogix PLC.

I want to map them to this structure

- Udt\_A\_Instance0  
\*\* Udt\_B\_Instance0  
\*\*\* Member0  
\*\*\* Member1  
\*\*\* Member2  
\*\*\* Member3  
\*\*\* Member4  
\*\* Udt\_B\_Instance1  
\*\* Udt\_B\_Instance3 etc
- Udt\_A\_Instance1  
\*\* Udt\_B\_Instance0  
\*\* Udt\_B\_Instance1  
\*\* Udt\_B\_Instance3 etc
- Udt\_A\_Instance2  
\*\* Udt\_B\_Instance0  
\*\* Udt\_B\_Instance1  
\*\* Udt\_B\_Instance3 etc

How can I go about this? Is there some automated way I could create this mapping or would I have to do this all my hand? I am running 8.1 BTW
