FAL/arrays RSLogix 5000

I'm trying to copy the contents of an array to another array. I'd like to start at different positions in the array.

ex:

array1[12] -> array2[0]
array1[13] -> array2[1]
array1[14] -> array2[2]

I'm looking to do it in one scan cycle. The FAL instruction falls short since the position of both arrays is dictated by [xxx.pos]

Use a copy (COP).


COP (array1[12], array2[0], 3)

As long as the data groups are continuous you can start and end wherever you want.

Could you use a copy instruction?
Like this
source=array1[12]
Dest=array2[0]
length=however many you need to copy

ok thanks got it.

COPy is the easiest way to do it, but just so you know, you can still do it with FAL by adding an offset in the destination expression.
