Extracting values from an array

[perauj]

I hope this is the right spot for this question.  I think I'm on the right track but can't seem to get this to work.

I have an elementary variable ARRAY [0..5] OF INT with some numbers and want to extract values from it with function blocks.

Attached is what I have so far.  It does what I want but can't seem to get values I want past the 0/n location.

Thanks, Jeff Perau

The EXTRACT block copies by bytes. You are using INTs which are 2 bytes long. SRC_POS needs to increment by 2 and CPY_NELEM should be 2 in order to get both bytes.
