Network Infrastructure for EtherNet/IP™

C-1

Appendix C EtherNet/IP and International Standards

EtherNet/IP is not just an open network based on the CIP specification. Its lower layers are based on

Internet and Ethernet standards. In addition, The EtherNet/IP™ Specification

is rapidly being

incorporated into international standards. This high degree of standardization assures users that

EtherNet/IP systems will work with Commercial Off-The-Shelf (COTS) Ethernet infrastructure devices

and Internet protocols, and be accepted in manufacturing systems around the world. Listed here are other

international standards related to EtherNet/IP.

Internet and Ethernet Standards

The Internet Engineering Task Force (IETF) publishes its standards under a series called Request For

Change documents (RFCs)

. EtherNet/IP is based on the following Ethernet and Internet standards:

RFC 768 User Datagram Protocol

RFC 791 Internet Protocol

RFC 792 Internet Control Message Protocol

RFC 793 Transmission Control Protocol

RFC 826 Ethernet Address Resolution Protocol

RFC 894 Transmission of IP Datagrams over Ethernet Networks

RFC 1112 Host Extensions for IP Multicasting

RFC 2236 Internet Group Management Protocol, Version 2

ISO/IEC 8802-3:1996 Information Technology, Telecommunications and information

exchange between systems, Local and metropolitan area networks,

Specific requirements, Part 3: Carrier sense multiple access with

collision detection (CSMA/CDD) access method and physical layer

specifications.

Protocols and Profiles

EtherNet/IP is a part of the following IEC and CENELEC standards:

IEC 61158:2003 (Type 2) Covers a wide range of application requirements from discrete

manufacturing automation to process control. It includes the CIP

application layer used by EtherNet/IP and other CIP-based networks,

and the mapping protocol for putting CIP on TCP/IP/UDP

IEC 61784-1:2003 CP 2/2 Type 2 Includes the communication profile defining how to extract the

relevant EtherNet/IP specifications from IEC 61158 documents

EN 61158:2003 (Type 2) European equivalent of the corresponding IEC standard
