I stumbled onto this behavior the other day, then went looking for old forum posts with the assumption that "there is nothing new under the sun," and sure enough, found this decade+ old thread (feel the Bern! ;)).

Anyway, here is my experiment suggesting at least that Data Files that are both contiguous and sequentially numbered* act as if their data are contiguous bits in memory. Environment: MicroLogix 1100 - Series B; RSLogix Micro Starter Lite.

Now what if the N-file had an odd number of elements i.e. would it pad the N-file so the subsequent Data Files are double-word aligned?

* Data File number increasing by 1
