You can use the "Process Values" function in DataDirect or "Property Reference" function in Bulk Data Manager to fetch data from any property into an Excel sheet. From excel you can export the values in almost any format to your application.
If you want cyclic transfer of data within 800xA, the Property Transfer Service can be used. N.B. do not use Property Transfer for critical data.
If you are using property transfer, 800xA help (hotkey F1) is very useful! I've done property transfer configuration just using step-by-step from help.
I did the logic in PG2 expression builder them paste in property expression. It is working properly.

I think we need some clarification. Do you need the values in CB/FD or are the calculation done in the controller?

Calculation will be done in FD,but I need just the method for trasnering the OPC Values from PLC Connect till FD. SO that further it can be calculated in FD.
