Quick Reference: Controller Area Network - CAN Bus - Versus Industrial Ethernet
At first glance, a comparison of the two networking technologies, Controller Area Network (CAN Bus) and Industrial Ethernet may appear as a battle between David and Goliath. On one side, you have the clear underdog, CAN Bus with its 1 Mbit/sec baud rate, its limited network length, and a maximum data length of 8 bytes per message. Compare that to the various Industrial Ethernet solutions (such as Ethernet I/P, EtherCAT, ProfiNet, Ethernet Powerlink, Modbus-TCP, and Sercos III) with its 100 Mbit/sec (and even up to 1000 Mbit/sec) transmission rate, unlimited data packages, and a (virtually) unlimited physical network length.
