  2. Reference： • [1]EtherNetIP030613.ppt • [2]Andrew S. Tanenbaum “Computer Network 4th” • [3] http://www.siemon.com/us/white_papers/03-03-25-ethernet-ip.asp EtherNet/IP by 張良豪/NTU-EE

  3. Introdcution： • Ethernet/IP is an industrial application layer protocol for industrial automation applications. Built on the standard TCP/IP protocols, it utilizes long established Ethernet hardware and software to define an application layer protocol for configuring, accessing and controlling industrial automation devices • Uses Standard IEEE 802.3 Ethernet • Uses the TCP/IP protocol suite • Also uses CIP (Control and Information Protocol) as the application layer protocol EtherNet/IP by 張良豪/NTU-EE

  5. IEEE 802.3 • Ethernet cabling From [2] EtherNet/IP by 張良豪/NTU-EE

  6. Encoding none of the versions of Ethernet uses straight binary encoding with 0 volts for a 0bit and 5 volts for a 1 bit. all Ethernet systems use manchester encoding due to its simplicity From [2] EtherNet/IP by 張良豪/NTU-EE

  7. CSMA/CD (Carrier Sense Multiple Access with Collision Detection) • When a station has data to send, it first listens to the cannel to see if anyone else is transmitting at the moment. If the channel is busy, the station waits until it becomes idle. • When the station detects and idle channel, it transmits. • If a collision occurs, the station waits a random amount of time to start all over again. EtherNet/IP by 張良豪/NTU-EE

  8. UDP/TCP/IP • IP(Internet Protocol): The internet layer defines an official packet format and protocol called IP. The job of the internet layer is to deliver IP packets where they are supposed to go. From [2] EtherNet/IP by 張良豪/NTU-EE

  9. TCP(Transmission control protocol) it is a reliable connection –oriented protocol that allows a bye stream originating on one machine to be delivered without error on any other machine in the internet. TCP also handles flow control. • UDP(User datagram protocol) it is an unreliable, connectionless protocol for application that do not want TCP‘s sequencing or flow control and wish to provide their own. EtherNet/IP by 張良豪/NTU-EE

  10. CIP(control and information protocol • The creators of Ethernet/IP based their protocol on a widely implemented standard used in DeviceNet and ControlNet called the Control and Information Protocol • CIP is a communications protocol for transferring automation data between two devices. It defines the access, object behavior, and extensions that allow disparate devices to be accessed using a common mechanism EtherNet/IP by 張良豪/NTU-EE
