EtherNet/IP Network
Overview The EtherNet/IP network offers a full suite of control, configuration, and data collection
services by layering the Common Industrial Protocol (CIPâ„¢) over the standard Internet
protocols, such as TCP/IP and UDP. This combination of well-accepted standards provides the
capability that is required to support information data exchange and control applications.
Micro850 and Micro870 controllers with firmware revision 20.011 or earlier support Explicit
messaging over the EtherNet/IP network. Micro850 (2080-L50E) and Micro870 (2080-L70E)
controllers with firmware revision 21.011 or later add support for Implicit messaging.
For information on Implicit and Explicit messaging and how to configure EtherNet/IP or USB
drivers, see the EtherNet/IP Network Devices User Manual, publication ENET-UM006
.
The controllers use socket interface transactions and conventional communication over the
EtherNet/IP network to communicate with Ethernet devices that do not support the
EtherNet/IP application protocol.
