Problems configuring an EIOC

We are testing out an EIOC and are trying to communicate with an Rockwell E300 starter via Ethernet/IP.  We have the EIOC commissioned and have all of the signals defined.  We are talking using Class 1 messaging and have the input / output assemblies setup correctly.  We have verified communications on the network with the E300 and a laptop.  However, our EIOC shows "No Comms" in diagnostics.  There are not very many settings to configure on the EIOC.  According to the LED's on the E300 starter it is online, but no master is scanning the bus.  Anyone have any experience with the newly released EIOC?

    We were able to resolve the issue by changing the number of Input / Output bytes to match the total available for the starter as opposed to only what we needed. Once We did this, the EIOC began scanning the I/O.
