Application of SmartWire-DT® 

 

 

How to use SmartWire-DT on EtherNet/IP® and 
Modbus TCP 

 

 

Application 

The EU5C-SWD-EIP-MODTCP Ethernet to SmartWire-DT gateway supports 
both EtherNet/IP and Modbus TCP Ethernet protocols. This allows any 
EtherNet/IP or Modbus TCP master to fully control and monitor all devices on the 
SmartWire-DT network. Devices that may be connected to SmartWire-DT include 
XT contactors and starters, M22 pushbuttons and pilot devices and digital and 
analog input and output modules. SmartWire-DT dramatically reduces wiring time 
and 

reduces panel complexity by consolidating complex circuit wiring into a 

single, durable 8-pole cable.  

 
Overview 
 

The purpose of this application note is to demonstrate how to configure a 
SmartWire-DT system and how to set up an Ethernet master to control and 
monitor all devices on that SmartWire-DT system. A Rockwell® CompactLogix® 
controller will be used to demonstrate EtherNet/IP connectivity to SmartWire-DT 
and an Eaton ELC-PV controller with Modbus TCP Ethernet master will be used 
to demonstrate Modbus TCP connectivity to SmartWire-DT. XT starters and M22 
pushbuttons and pilot devices will be connected to the SmartWire-DT network. 

 
 
Configuring the SmartWire-DT System using SWD-Assist® 
 

SWD-Assist is a software tool for configuring a SmartWire-DT system. This 
software allows the user to fully build and configure a system offline without any 
hardware present; then download to the system once the hardware is in place. 
Or, connect the software to a wired and powered SmartWire-DT system and use 
the auto-configuration feature to map the data for all connected devices into the 
SmartWire-DT Ethernet gateway (EU5C-SWD-EIP-MODTCP).
