  • Page 16: Tcp/Ip And Udp/Ip

    Chapter 3 EtherNet/IP Overview The encoder is an I/O adapter in the EtherNet/IP. It receives and sends explicit and implicit messages either cyclic or on request (polled). TCP/IP and UDP/IP EtherNet/IP uses TCP/IP or UDP/IP for communication. (TCP is transmission control protocol and UDP is user datagram protocol.) Implicit messaging is used for real-time communication between a programmable logic controller (PLC) and the encoder in EtherNet/IP.

  • Page 17: Understanding The Producer/Consumer Model

    EtherNet/IP Overview Chapter 3 The Ethernet data field consists of several nested protocols: • The IP datagram is transported in the user data of the Ethernet data field. • The TCP segment or the UDP datagram is transported in the user data of the IP datagram.

  • Page 18: Specifying The Requested Packet Interval

    Chapter 3 EtherNet/IP Overview Specifying the Requested The requested packet interval (RPI) is the update rate that is specified for a particular piece of data on the network. This value specifies how often to Packet Interval produce the data for that device. For example, if you specify an RPI of 50 ms, it means that every 50 ms the device sends its data to the controller or the controller sends its data to the device.
