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?
