EtherNet/IP Overview
The EtherNet/IP protocol is a multi-discipline, control and information
platform for use in industrial environments and time-critical applications. The
EtherNet/IP network uses standard Ethernet and TCP/IP technologies and an
open, application-layer protocol called the Common Industrial Protocol (CIP).
The open, application-layer protocol makes interoperability and
interchangeability of industrial automation and control devices on the
EtherNet/IP network a reality for automation and real-time control applications.
The EtherNet/IP protocol follows these standards:
• IEEE 802.3—Standard Ethernet, Precision Time Protocol (IEEE-1588)
• IETF—Internet Engineering Task Force, standard Internet Protocol (IP)
• IEC—International Electrotechnical Commission
• ODVA—Open DeviceNet Vendor Association, Common Industrial
Protocol (CIP)
