If you're just looking to verify OPC paths, just export to L5X (after disabling any source protection) and use @pturmel's Ethernet/IP module to import the L5X into a host device.
You won't get any sort of IO simulation, as if simulating a PLC, but your connections will work and you can change tag values and watch the changes happen in real-time.
Also note, small difference with how arrays of BOOLs are handled in the Logix driver and Phil's module.
