4.3 Ethernet/IP 
Introduction 
EtherNet/IP is an Industrial Ethernet Protocol defined by the ODVA association. The protocol is open 
to the public and vendors can implement EtherNet/IP into their industrial devices without incurring a 
license fee. Many vendors have adopted this protocol as the standard communication protocol 
between devices. For example, Rockwell Automation uses EtherNet/IP as the standard protocol for 
their Logix controllers over Ethernet networks.   
To allow complete integration with a Rockwell system, Weidmüller switches not only provide a 
full-functioning of industrial network infrastructure, but also enable the SCADA system to monitor the 
status of the switches as well as that of the PLCs, making the switches part of a Rockwell system. 
Messaging Types 
EtherNet/IP supports two types of communication methods for EtherNet/IP devices: Explicit 
Messaging and Implicit Messaging. Explicit Messaging is unscheduled and is used for a 
request/response communication procedure (or client/server procedure). Explicit Messaging uses 
TCP/IP over Ethernet. Implicit Messaging is scheduled and is used for a producer/consumer 
communication with UDP over Ethernet. Implicit Messaging is also called I/O Messaging. 
4.3.1 Configuring Ethernet/IP on Weidmüller Switches 
The following steps show how to enable the Ethernet/IP function on the Weidmüller switch: 
1.  Connect the configuration PC to the Switch
