Ethernet is a communications technology widely used to solve problems in industrial Fieldbus communications. Let me illustrate—EtherNet/IP, Profinet, PowerLink, EtherCAT, Sercos III, Foundation Fieldbus HSE and CC-Link IE are all fieldbuses and use Ethernet technology at layers 1 and 2 (physical and data link layer). Why do I say they are fieldbuses? They are all in the International Electrotechnical Committee (IEC) Standard 61158 that defines industrial fieldbuses. Each has different ways to use Ethernet, but none of them…Full Story
