Hi guys! I have problem with communication between
Logix 5561 and Flex 1794AENT.

I have Logix 5561 connected to EtherNet/IP network, via two modules:

1. 1756-ENBT - talking with PanelView 1250
2. 1756-EN2T - talking with 7 remote 1756-ENBT(5 chassis(13 slots each))

I have to add 8x1794-AENT, and in future five more PanelView's

I tried to add 1794-AENT same way like 1756-ENBT, but no any luck.

Can I talk with 8x1794-AENT via 1756-EN2T(already working with 7 remote racks)?

How to setup communication with 1794- AENT in RSLogix 5000?

Can I talk with five PanelViews via one 1756-ENBT?
 
What do you mean "Add the 1756-ENBT" ? You don't add that to the EN2T. It is a separate Ethernet module.
Drop it in the rack, give it a name, go to the "Ethernet" network under the module, right click, "New Module", "Communications, 1794-AENT".

If that doesn't work, you need to tell some basics, like, oh, say, what rev of firmware for the CPU and the modules you are adding.

You cannot add Flex I/O online

Yes

It just works when you add the modules - just as if it was 1756 I/O

Yes
 
You might need to configure such a large amount of remote IO as "Rack Optimisation"
