1756-EN2T/C Can't browse backplane

I have a 1756-L55 and an ENBT that have been working great. I then replaced the ENBT with an EN2T/A and it still worked. I now need to get an EN2T/C working with the system.

I swapped in the EN2T/C, setup the IP address and can connect to it and browse to it in RSLinx (tried both 2.59 and 3.60).

I cannot see anything on the backplane besides the EN2T when i try to browse the backplane.

Another thing that is strange is when I try to browse the backplane from the website/IP address utility, it doesn't show any modules either. I have tried a 1756-L61 and L55 and can't get the EN2T/C to see anything on the backplane

I am on 5.008 for the EN2T/C but also tried 3.XXX with the same issue

Any help is much appreciated!

EDS file missing or wrong version?

I tried updating the EDS file for the EN2T multiple times through RSLinx :/

rslinx->Tool->Register?

Using the EDS Hardware Installation Tool, correct

Is it possible the backplane communication is just faulty? Is this something that happens? The module gets power etc, can communicate externally, but cant communicate on the backplane properly?

if the register Success and you using right EDS,right version maybe others Interrupts.

reboot plc and computer.

or we use RSNetworx EDS Wizard or check on Communication Adapter 1756-EN2T/C
installed or not.
