Siemens ProfiNet and Rockwell EtherNet/IP are fundamentally different application protocols and cannot directly communicate with one another. PC-based middleware is a common solution; OPC Mirror software from several vendors can be used. Hardware gateways are also common; HMS Fieldbus' "Anybus-X" device will link data between ProfiNet and EtherNet/IP systems. The most common link that I see established (and install myself) between A-B and Siemens systems is Profibus DP.
