How to get the Data from Allen Bradley 20-Comm-E to EIOC?

I am trying to get data from Allen Bradley Powerflex70 VFD using 20-Comm-E Module. I have configured the following Assembly Instance and Bytes

Input:        Bytes:24                             Assembly Instance: 1

Output:    Bytes : 20                           Assembly Instance: 2

Config                                                Assembly Instance :6

I have also configured all the relevant signals, but so far I have not been able to get any data from 20-comm-e into EIOC and it shows signals status as bad. Similarly the 20-Comm-E port also shows no communications.

I tried using the AB PLC (Compact Logix) using a generic device setup with the above assembly instance and bytes for the same 20-Comm-E and I am able to receive/send all signals.

At the same time I also connected Allen Bradley E300 Overload relay to my EIOC and I could connect without any issues.

Can Somebody help to check if I am missing something here fo 20-COMM-E setup? Please can you help me on this?
