controllogix with wonderware on ethernet

How can i create tags in wonderware to communicate with CLX through ethernet?

Modbus, use tcp/ip, you will have to link your tag database to a modbus database(excel).

Modbus?
Why?
Just use RSLinx (any version that supports OPC), and WonderWare's OPC Client. Then you just access tags by name.

The WonderWare DI/DA servers can also talk directly to a ControlLogix over EthernetIP.
