EtherNet/IP, PROFINET, or both?
EtherNet/IP and PROFINET are two protocols that utilize and add value to standard ethernet technology. Speed is often mentioned as a key benefit of PROFINET, while interoperability often goes into the EtherNet/IP column. Yet when it comes to one over the other, it's not so black and white. For product design and development, you may want to hedge your bets and support both.
