What you can do is the following:

- Make an in_out variable of type udt
-Create a db with a variable of type: :ARRAY[1..100] OF UDTxx;

Each time you call the SCL code (compiled as fb block), you can select the in_out variable and direct it to the dv where you created the array. You can now say if you want array 1,2,3 etc...

Is this what you mean?

You can process the variables in the udt like this:


DRIVE :UDT;



IF DRIVE.MAN_ON
THEN manual_on :=TRUE;
END_IF;

where MAN_ON is a variable in the UDT and manual_on is a output.
