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 122)".
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).
Electronic Data Sheets (EDS) are electronic datasheets for describing devices.
The EDS required for EtherNet/IP operation can be found in "System > Load&Save
(Page 77)".
