EtherNet/IP Overview

EtherNet/IP is an industrial multi-vendor network that uses Ethernet. The EtherNet/IP specifications
are open standards managed by the ODVA (OpenDeviceNet Vendor Association). EtherNet/IP is used
by a wide range of industrial devices.
Because EtherNet/IP uses standard Ethernet technology, various general-purpose Ethernet devices
can be used in the network.
EtherNet/IP has mainly the following features.
• High-speed, High-capacity Data Exchange through Tag Data Links (Cyclic Communications)
The EtherNet/IP protocol supports implicit communications, which allows cyclic communications
(called Tag Data Links) with EtherNet/IP devices.
• Tag Data Links are set at the specified communication cycle for each application regardless
of the number of nodes
Because the data is exchanged over the network at the refresh cycle that is set for each connection
regardless of the number of nodes, that refresh cycle will not increase even if the number of nodes
increases. (Data exchange in the connection is kept in synch)
Because the refresh cycle can be set for each connection, each application can communicate at its
ideal refresh cycle. (For example, interprocess interlocks can be transferred at high speed, while the
production commands and the status monitor information are transferred at low speed.)
Precautions for Correct Use
On a network to which many devices are connected, performance may drop (e.g., responses
may be delayed or packets lost) or communications errors may occur when there is temporarily
high traffic on the network.
Test the operation under actual conditions before you start actual operation of the system.
