Already in edition 2 of the fieldbus profile first profiles based on Ethernet as physical layer are included. All this new developed Real-time Ethernet (RTE) protocols are compiled in IEC 61784 Part 2 as "Additional profiles for ISO/IEC 8802 3 based communication networks in real-time applications". Here we find the solutions Ethernet/IP, three versions of PROFINET IO - the classes A, B, and C - and the solutions of P-NET, Vnet/IP TCnet, EtherCAT, Ethernet POWERLINK, Ethernet for Plant Automation (EPA), and also the MODBUS with a new Real-Time Publish-Subscribe MODBUS-RTPS and the legacy profile MODBUS-TCP.
