1.1 What is EtherNet/IP?
EtherNet/IP is a standard network in which the CIP (Common Industrial Protocol), defined by EN50170 and IEC61158
standards and proven in DeviceNet, is implemented over standard Ethernet and TCP/IP protocols.
EtherNet/IP can handle the I/O messages that are used to control devices or to perform interlock communication
between the controllers in real time, and also the explicit messages that check the configuration of and diagnose field
devices. Since EtherNet/IP uses routing technology that is compatible with DeviceNet, it is possible to send and receive
messages between devices in different networks by simply connecting EtherNet/IP and DeviceNet with a CIP router
(gateway), without using additional networking and programs.
The following figures show the protocol stack configuration of EtherNet/IP (includes DeviceNet) and the protocol
stack concept of EtherNet/IP.
