4 EtherNet/IP Introduction EtherNet/IP Protocol (Ethernet Industrial Protocol)

5 EtherNet/IP Introduction EtherNet/IP EtherNet/IP(Ethernet Industrial Protocol) is a communications protocol originally developed by Rockwell Automation, currently managed by the Open DeviceNet Vendors Association (ODVA) and designed for use in process control and other industrial automation applications Behaviors Transfer of basic I/O data via User Datagram Protocol (UDP)-based implicit messaging Uploading and downloading of parameters, setpoints, programs and recipes via TCP (i.e., explicit messaging.) EtherNet/IP makes use of well known TCP port number for explicit messaging and UDP port number 2222 for implicit messaging EDS (electronic data sheet) file

6 EtherNet/IP Introduction Encapsulation Message Ethernet header (14 bytes) IP header (20 bytes) TCP header (20 bytes) Encapsulation message CRC Encapsulation header (14 bytes) Command specific data Command (2 bytes) Length (2 bytes) Session handle (4 bytes) Status (4 bytes) Sender Context (8 bytes) Options (4 bytes) To be defined by different Command

17 Implicit and Explicit Message Explicit The block is then triggered as needed. This type of communication does not load the network with continuous responses.

18 Implicit and Explicit Message

19 Implicit and Explicit Message Implicit The implicit form of communication does not require triggering. Implicit messaging is deterministic. This means it is possible to estimate the data s travel rate. RPI (Request Packet Interval)must be set before connecting.
