As I recall, this is well-nigh impossible.
I seem to remember the only way of doing this is to 'Copy' the original module, 'Paste' it where you want it to be, and then 'Delete' the original. Of course, as soon as you Paste the module it will have a new address assigned, so if you want to have the same address as the original one had, you'll have to edit that by hand.
It's easy enough to drag-and-drop modules within a single slave or I/O rack, but doing this between slaves isn't a feature I remember in STEP7
Can anyone help by proving me wrong?

Ken.
