Siemens S7-300 Hardware Config rearrangement

G'day Guys,
I have a S7-314C-2 DP Processor (6ES7 314-6CF00-0AB0) which has a full rack this has a IM365 module which breaks it out another rack with a spare slot.
I need to add a CP343 Lean module (Ethernet card) to the system yet Hardware manager won't allow the CP343 Lean to sit on the rack with a spare slot (I guess this is because the CP343 would bottleneck at the IM365?) hence I need to move a I/O module from the first rack to the second to allow me to place the CP343 on the same rack as the 314C. Is there an easier way to do then than having to A. Physically swop a card to make space on the same rack as the 314C and B. If I have to swop the cards do I manually have to reconfigure all the addresses using a global change?

I'm really after a couple of pointers as to problems I may encounter or tips to make this easier/less risk to production

Cheers.
Rob

Hi and welcome to the forum.

What is the purpose of the LEAN card?

You might be happy with an S7LAN MPI-Ethernet converter instead.
Here are the variants from IBH:

... and from PI:

Did you try to install the CP 343 next to the IM 365 in the
main rack?

He says he has a full rack, so he must do what he already suggest.
The netlink adapters is a possible alternative.

.. or replace the 314C-2DP with a 314C-2PN/DP (6ES7 314-6EH04-0AB0)?

Hi Guys,

Thanks for your Advice I previously have used a NetLink converter on a S7-400 profibus which worked fine however I already have a CP343 Lean card so its hard to justify another ~$800 on a Netlink converter.

If the interface module always uses slot 3 and I have the IM365 in slot 3 does this mean that I cant put the CP343 next to it in slot 4 pushing the I/O's along moving the last one to the next rack?
Thanks

Rob
