33LayersEtherNet/IP is the implementation of CIP over TCP/IP and Ethernet (IEEE 802.3).The EtherNet/IP specification defines :

4Ethernet/IP, like the others CIP network, follows the Open system interconnection model, which define a framework for network protocol in 7 layers :

4 EtherNet/IP uses standard IEEE 802.3 technology at the Physical and Data Link Layers. This standard provides a specification for physical media, defines a simple frame format for moving packets of data between devices and supplies a set of rules for determining how network devices respond when two devices attempt to use a data channel simultaneously. This is known as CSMA/CD (Carrier Sense Multiple Access/Collision Detection). The Physical Layer

CIP uses its object-oriented design to provide EtherNet/IP with the services and device profiles needed for real-time control applications and to promote consistent implementation of automation functions across a diverse ecosystem of products. In addition, EtherNet/IP adapts key elements of Ethernets standard capabilities and services to the CIP object model framework, such as the User Datagram Protocol which EtherNet/IP uses to transport I/O messages.

5 As a network with an active infrastructure, EtherNet/IP is typically configured using a series of network segments constructed of point-to-point connections in a star configuration. The core of this network topology is an interconnection of Ethernet Layer 2 and Layer 3 switches, can accommodate an unlimited number of point-to-point nodes. The Physical Layer

The other ports of the switch can be connected using twisted pair or fiber cables to the control devices for that part of the machine or manufacturing process. EtherNet/IP networks can be either isolated (not connected directly to the enterprise network) or non-isolated

The Datalink LayerIEEE's 802.3 specification is also the standard used for transmitting packets of data from device to device on the EtherNet/IP Data Link Layer. Ethernet employs a CSMA/CD media access mechanism that determines how networked devices share a common bus (i.e., cable), and how they detect and respond to data collisions.8Is the lowest layer of TCP/IP,where IP residesIs also where the Address ResolutionProtocol (ARP) residesWhen a device want to transmitan IP datagram to other device:+look up the ethernet address+or use the internal ARP table

The network Layer9Note that: Ethernet broadcast messages pass through hubs and switches and bridges, but they do not pass through routersEthernet addresses cannot be changed and IP addresses may be changed

Ethernet addressIp addressThe network Layer10There are three important binary properties that serve as the basis for the classification of transport layer protocols:1. Connection-oriented vs. Connectionless2. Stateful vs. Stateless3. Reliable vs. Unreliable Based on the above classification, we have two protocol TCP and UDP looks like complete oppositesThe transport Layer1111

The transport Layer12EtherNet/IP uses the Common Industrial Protocol (CIP), a strictly object-oriented protocol, at the upper layers. Each CIP object has attributes (data), services (commands) and behaviors (reactions to events).13The upper LayerProducer-consumer communication model"device types" & "device profilesSeamless bridging and routingMAIN FEATURES14The upper LayerCIP's producer-consumer communication model

15The upper LayerCIP also includes "device types" for which there are "device profiles.specify the set of CIP objects, configuration options and I/O data formats.promote a common application interface for a given device type and interoperability in networks comprised of devices from multiple vendors.

16The upper LayerSeamless bridging and routing is perhaps the most significant advantage for users of CIP Networks for it is this mechanism that most protects the user's investment for the future.
