4.3 EtherNet/IP
EtherNet/IP
EtherNet/IP (Ethernet/Industrial Protocol) is an open industry standard for industrial real-time
Ethernet based on TCP/IP and UDP/IP. With EtherNet/IP, Ethernet is expanded by the
Common Industrial Protocol (CIP) at the application layer. In EtherNet/IP, the lower layers of
the OSI reference model are adopted by Ethernet with the physical, network and transport
functions.
You configure EtherNet/IP in "System > EtherNet/IP (Page 209)".
Common Industrial Protocol
The Common Industrial Protocol (CIP) is an application protocol for automation that supports
transition of the field buses in Industrial Ethernet and in IP networks. This industry protocol is
used by field buses/industrial networks such as DeviceNet, ControlNet and EtherNet/IP at the
application layer as an interface between the deterministic fieldbus world and the automation
application (controller, I/O, HMI, OPC, ...). The CIP is located above the transport layer and
expands the pure transport services with communications services for automation engineering.
These include services for cyclic, time-critical and event-controlled data traffic. CIP
distinguishes between time-critical I/O messages (implicit messages) and individual query/
response frames for configuration and data acquisition (explicit messages). CIP is object-
oriented; all data "visible" from the outside is accessible in the form of objects. CIP has a
common configuration basis: EDS (Electronic Data Sheet).
