WHAT IS ETHERNET? ETHERNET history – – developed in 1973 as shared medium – – bandwidth 10 Mbps – – bus topology – – CSMA/CD procedure for media access

OLD ETHERNET NOT DETERMINISTIC NOT CHOSEN FOR FACTORY NETWORKS, LACKED DETERMINISM NOT CHOSEN FOR FACTORY NETWORKS, LACKED DETERMINISM DETERMINISM = ABILITY TO PREDICT DETERMINISM = ABILITY TO PREDICT ETHERNET WAS BASED ON SHARED BACK BONE AND HALF DUPLEX ETHERNET WAS BASED ON SHARED BACK BONE AND HALF DUPLEX FAST ETHERNET DEVELOPED FAST ETHERNET DEVELOPED

FAST ETHERNET ETHERNET today – – scalable bandwidth with 10/100/1000 Mbps – – switched “Full Duplex” connection without collisions – – IEEE standards for prioritization and flow control – – standards for Copper, Fiber, Plastic, and Wireless transmission

WHAT IS ETHERNET/IP? IP = INDUSTRIAL PROTOCOL IP = INDUSTRIAL PROTOCOL OPEN STANDARD FOR INDUSTRIAL NETWORKS OPEN STANDARD FOR INDUSTRIAL NETWORKS USES STANDARD ETHERNET AS A BASE USES STANDARD ETHERNET AS A BASE ADDS AN APPLICATION PROTOCOL FOR FACTORY AUTOMATION ADDS AN APPLICATION PROTOCOL FOR FACTORY AUTOMATION
