Processor wont run after moving CRP card

Processor: 140 CPU 652 60 (Modicon Quantum)
Software: Unity 7.0
Firmware: 3.10

Setup:

I'm converting my local rack into a remote rack and creating a new local rack. Current local rack is a 16-slot. New one will be a 6-slot. In my program I have created the new remote rack and moved all of the cards to it. I am left with a power supply (slot 1), CPU (slots 3,4) and CRP (slot 14).

Problem:

When I move the CRP card from slot 14 to slot 6 the project builds, but it wont let me go into run mode. I don't get an error message in Unity, but in the Stop Code menu on the processor it has error 0400 (per Google: Start-of-network (SON) did not start a segment).


Any suggestions?


Thanks

Update: If I remove the CRP the processor will go to run, but when I put it back it stops.

Hi Rank

I Will try and replicate.. can you just confirm if its an ethernet CRP or coaxial CRP?

Coaxial (140 CRP 931 00)
