EtherNet/IP (Industrial EtherNet Protocol) is a communication system proper for
the industrial environment. This system allows application data exchange, time-
restricted or critical, between industrial systems. The EtherNet/IP is available for
simple devices such as sensors/actuators as well as for complex devices such
as robots, PLCs, keypads and inverters.
The EtherNet/IP application layer protocol is based on the Control and Information
Protocol (CIP) layer that is used in both DeviceNet™ and ControlNet™. The CIP
organizes the devices as collection of objects and defines the methods and
procedures for data access. Furthermore, the EtherNet/IP uses the standard
IEEE 802.3 for the low level layers and the TCP/IP and UDP/IP protocols for the
intermediary layers to transport the CIP packets.
Therefore, the infrastructure used by the EtherNet/IP is the same used by the
corporate computer networks (EtherNet). This fact extends considerably the
means of controlling and monitoring the devices connected to the network:
Availability of application protocols (HTTP, FTP, etc.).
Integration between the assembly line and the corporate.
It is based on a widely used and accepted standard.
Greater data flow than the standard protocols used for the industrial automation.
