Ethernet/IP Functional Principle Approaches Modbus/TCP Consumer / Producer Model • Advantage: very efficient for slave-to-slave Communication • Disadvantage: requires Broadcast communication and thus filtering in each device Ethernet/IP Powerlink producer consumer consumer accept consumer accept PROFINET SERCOS III prepare filter filter filter send receive receive receive EtherCAT broadcast communication Summary February 2008 Industrial Ethernet Technologies By applying broadcast or multicast communication, the switches cannot forward incoming frames to a single destination port only - so they act like (full-duplex) Hubs, but with larger delay.
