Ethernet Industrial Protocol (EtherNet/IP) is an open industrial networking standard. It has been developed by Rockwell Automation, managed by ODVA (Open DeviceNet Vendors Association) and designed for use in process control, hard-time systems, and industrial automation applications..
EtherNet/IP is an open network because it uses standard Ethernet IEEE 802.3, TCP/IP protocol suite, and CIP (Common Industrial Protocol), the real-time I/O and information protocol that DeviceNet and ControlNet networks use.
What is EtherNet/IP?
FEATURES
Offer Producer-Consumer service that enable users to control, configure and collect data.Provide flexible installation options leveraging commercially available industrial infrastructure products, including copper, fiber, fiber ring and wireless solutions.Compatible with general communication standards, including OPC, TCP/IP, HTTP, FTP, SNMP, DHCP.*One-to-one (unicast), one-to-many (multicast), and one-to-all (broadcast) communication via TCP
WHAT IS ETHERNET/IP?
The Physical Layer EtherNet/IP uses the standard IEEE
802.3 model at the Physical and Data Link Layers. The Physical Layer is responsible for bit-level transmission between network nodes, and defines specifications for electrical signals (copper networks) or the characteristics of light signals (fiber optic networks). The Physical Layer also defines items such as: connector types, cable types, voltages, and pin-outs.
The Data Link Layer The IEEE 802.3 specification is also used for transmitting packets of data from device to device on the EtherNet/IP Data Link Layer. The Data Link Layer is concerned more with the interactions of multiple devices (i.e., at least two) with a shared medium. (EtherNet/IP) uses a CSMA/CD Media Access Control (MAC) model that determines how networked devices share a common bus (i.e. cable), and how they detect and respond to collisions between packets.
The Network and Transport Layers The Network and Transport Layers use
TCP/IP Suite to send messages between one or more devices. At these layers, messages used by all CIP networks are encapsulated.
TCP/IP encapsulation allows a node on the network to embed a message as the data portion in an Ethernet message. The encapsulation technique uses both the TCP and UDP layers of the TCP/IP suite and provides the method that allows CIP to be implemented transparently on top of Ethernet and TCP/IP.
EtherNet/IP uses two forms of messaging and the appropriate resources at the nodes, as defined by CIP standard• Unconnected messaging is used in the connection establishment process and for infrequent, low-priority messages. Unconnected messages on EtherNet/IP utilize TCP/IP resources to move messages across Ethernet, asking for connection resource each time from UCMM. • Connected messaging EtherNet/IP utilizes resources within each node that are dedicated in advance to a particular purpose, such as frequent explicit message transactions or real-time I/O data transfers. Connection resources are reserved and configured using communications services available via the CMM.
Three transmission types used in an (EtherNet/IP) network: Information I/O Data. Real-time Interlocking.

CIP ( Common Industrial Protocol) is a media independent, connection-based object oriented protocol designed for automation applications.
It encompasses a comprehensive set of communication services for automation applications: Control, safety, synchronization, motion, configuration and information.
