Ethernet Network
and EtherNet/IP Protocol
The Ethernet network is a local area network designed for the
high-speed exchange of information between computers and related
devices. With its high bandwidth (10Mbps to 100Mbps), an Ethernet
network allows many computers, controllers, and other devices to
communicate over vast distances.
With an Ethernet network you have many possibilities because you
can maximize communication between the great variety of equipment
available from vendors.
An Ethernet network provides enterprise-wide systems access to
plant-floor data. At the application layer, EtherNet/IP is the
implementation of the Control and Information Protocol (CIP) on the
Ethernet network. Ethernet/IP is an open protocol that enables
multi-vendor integration.
Additionally, EtherNet/IP uses the protocols used by the Internet.
Both the Ethernet PLC-5 and Ethernet Interface Module contain
features that allow you to use the Internet to access product
information and to create and enhance application diagnostics. For
more information on these features, refer to page 15 of the Controller
Choices section.
