1 EtherNet/IP EtherNet/IP - Partners in Manufacturing Excellence The answer for Interoperability in Industrial Automation Mark Daniels Product Manager Rockwell Automation

2 Agenda What is EtherNet/IP Why was EtherNet/IP invented Multi vendor support of EtherNet/IP Which products support EtherNet/IP What are the new applications Generic Ethernet pros/cons Why and where can you use EtherNet/IP 2

3 What is EtherNet/IP (IP-Industrial Protocol) Open Industrial Network Standard based on Ethernet technology EtherNet/IP uses exclusively COTS (Commercial Off The Shelf) technology EtherNet/IP allows you to Configure, Collect, and now to Control data EtherNet/IP provides interoperability among products from various vendors 3

4 What is EtherNet/IP How is EtherNet/IP defined: EtherNet/IP uses standard IEEE Ethernet It uses the TCP/IP protocol suite And the CIP (Control and Information Protocol) as the application layer protocol All of these technologies are OPEN and widely accepted 4

5 EtherNet/IP Communication Stack Spec. downloadable at at Application Presentation Session Transport Network CIP Control and Information Protocol UDP IP-Multicast IP TCP EN Standard IEC Standard Request for Comments UDP/TCP/IP O P E N Link Physical Ethernet MAC Ethernet Physical IEEE Object Orientated Application Layer Protocol 5

6 What is it? Basic Ethernet - Physical media BUS Topology All nodes are connected using a backbone which connects other segments Where is it used? Bus topology is mainly used in existing applications when coax media is desired. STAR Topology What is it? Nodes are connected to an Ethernet switch/hub Where is it used? Star topology is used with twisted pair and fiber optic wire. New applications where control is required Bus (10BASE-2 Ethernet) (10BASE-5 Ethernet) Star (10/100BaseTX Ethernet) (100BaseFX Ethernet) For Control applications we recommend our customers to to use Ethernet switches to to minimize collisions

7 Basic Ethernet - Internet Protocols EtherNet/IP uses IP as network protocol TCP for explicit messages - Program Up/Down load, MSG Instructions, etc.. UDP for implicit messages - I/O Control, Interlocking, etc.. Advantage: UDP is several times faster than TCP CIP (Control and Information Protocol) Gives generic Ethernet Industrial Functionality It allows us to Configure, Collect and now Control data Provides the Producer/Consumer model on Ethernet Standard Ethernet, TCP/UDP/IP, plus CIP defines EtherNet/IP 7

8 TCP/IP Protocol Suite Control and Information Protocol provides Industrial Services Process Layer FTP HTTP DNS CIP SNMP BOOTP DHCP Host - to - Host Layer TCP UDP Internet Layer OSPF IGRP ICMP IGMP ARP IP RARP Network Access Layer Any IP based network (i.e., Ethernet) 8

9 What ControlNet is EtherNet/IP CIP protocol implemented on all 3 core networks: DeviceNet, ControlNet, EtherNet/IP Control and Information Protocol (CIP) Common Object Library Common Device Profiles Common Control Services Common Routing For Data Collection, Configuration and Control CSMA/NBA CTDMA TCP/UDP/IP CSMA/CD Physical layer Physical layer Physical layer DeviceNet ControlNet EtherNet/IP

10 Why was EtherNet/IP invented Generic Ethernet is a technology customers are asking for Generic Ethernet is very well known and broadly supported by many vendors EtherNet/IP will be the right fit for our customers application Functionality has been added to make Ethernet appropriate for control applications 10

29 Ethernet - Misconceptions Misconception #1 It s cheap Misconception #2 I can use COTS products on the plant floor Misconception #3 100Mb Ethernet will outperform everything Misconception #4 EtherNet/IP will replace ControlNet 29

30 Ethernet - Misconceptions It s cheap! -- I I can use COTS products on on the plant floor COTS hardware products are not as reliable as industrial products Temperature rate, MTBF - industrial Ethernet products are about 3-4 times more expensive - adds cost You need to add cost for every point to point connection due to the use of a hub/switch - adds cost If an Ethernet switch fails all connected nodes will fail too Additional effort to address Security issues with open systems - adds cost Cost savings are in in maintenance and support, not necessary on on the initial purchase 30

31 Ethernet - Misconceptions 100Mb Performance will be incredible EtherNet/IP will replace ControlNet The bottleneck for performance is always the end node not the wire speed 10Mb Ethernet is not twice as fast as 5Mb ControlNet 100Mb Ethernet will not be 10 times faster than 10Mb ControlNet - what does EtherNet/IP not offer HIGH determinism, easy redundancy, bus topology for control applications, passive physical media, intrinsically safe connectivity, available product offering, etc.. 31

32 Advantages of EtherNet/IP Why is EtherNet/IP demanded: Existing knowledge about Ethernet is tremendous many customers have already an Ethernet support group Well established network standard, customer acceptance rate is favorable Easy access to and from the Internet Simple to wire, easy to debug and maintain Support of 10/100Mb product mix 1000 s of of Ethernet products with all kinds of of functionality are already on the market 32

33 Where does EtherNet/IP fit into your plant EtherNet/IP Applications Adaptable in new and/or existing applications Easy to implement due to existing infrastructure/knowledge EtherNet/IP integrates seamless with existing DeviceNet and/or ControlNet applications Wherever you want a 100% open Network technology backed from multiple user organizations If you want to implement an open Ethernet network NOW (no other specification exists at this time) Cost savings for you on: maintenance, support, training, development, etc.. 33

34 Where does EtherNet/IP fit into your plant EtherNet/IP Applications continue IT and manufacturing personnel teaming on projects. If you want to lean your Network architecture to a one-network control and information solution. If your application is more concerned with simplified installation than highly deterministic I/O data delivery If you want to protect your investment in Ethernet technology (e.g. standard installation and support tools) Cost savings for you on: maintenance, support, training, development, etc.. 34

35 EtherNet/IP The door is open for EtherNet/IP The technology is here NOW - Ready to use Time To Market advantage of EtherNet/IP offers a great chance of becoming a global standard
