Rapid REMS platform - Ethernet/IP Explicit Message

Hi:

I am evaluating to use the Rapid with REMS platform as embedded solution to integrate into existing DeviceNet slave product to enable the Ethernet/IP capability.

After reading thru integration guide and the Rapid software code, I see the solution provides interface for host processor to read/write I/O data (Class 1 connection) but not for explicit message (Class 3 connection) .

So the question is how the host processor can handle explicit messaging thru the Rapid platform?

Thanks
