Keep in mind that Logix Emulate (all versions) does not listen for EtherNet/IP connections. You must make an OPC connection, not a native driver connection.
Rockwell's new Logix Echo emulator does listen for EtherNet/IP connections and can be reached with Ignition's native driver. (And my new one, fwiw.)
If you need to emulate older firmware, and are trying to truly replicate what will happen with the native driver in the future real application, you probably want to use SoftLogix, not Emulate.
