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).

- Page 1 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.
- Page 2 After downloading and installing SWD-Assist, double click its icon on the desktop to start the software and the following screen will open. This is the offline environment for building a SmartWire-DT system. To accomplish this all part numbers for the equipment being connected to this system must be known.
- Page 3 IP address for the module. Disable BootP and DHCP to use a static IP address. Next drag and drop the SmartWire-DT node devices in the order that they are listed in the previous section. You may need to expand sections on the left...
- Page 4 portion of the screen to reveal these devices. After dropping the first device on the project screen, drop the next one on the wire between the previous device and the terminator that was automatically added when the first device was added.
- Page 5 Connect the SmartWire-DT Ethernet gateway to the SmartWire devices and apply power. Note: the connected devices must match the offline configuration you set up in your project. Connect the SmartWire-DT Ethernet gateway to your PC using the EU4A-RJ45-USB-CAB1 cable or equivalent.
- Page 6 This will download the offline project just created to the Ethernet gateway. The SmartWire-DT system is now ready to be controlled and monitored with an EtherNet/IP or Modbus TCP Ethernet master. Please refer to the EtherNet/IP or Modbus TCP section below for additional information on configuring these master modules to control and monitor the devices on the SmartWire-DT system.
- Page 7 7. Click the Online button then select the PC to Device button under the Planned Configuration to download the modified project to the gateway. The SmartWire-DT system is now ready to be controlled and monitored with an EtherNet/IP or Modbus TCP Ethernet master. Please refer to the EtherNet/IP or Modbus TCP section below for additional information on configuring the network master to control and monitor the devices on the SmartWire-DT system.
- Page 8 SmartWire-DT system via the EU5C-SWD-EIP-MODTCP Ethernet gateway. The SmartWire-DT gateway is a node on Modbus TCP and a master on the SmartWire-DT network. The data for each SmartWire-DT device connected to the gateway is mapped to the Input and Output images in the gateway.
- Page 9 Starting address for the Input data: 0, Length = 5 registers Starting address for the output data: 2048, Length is 4 registers When clicking to select each SmartWire-DT device attached to the SmartWire- DT gateway in the offline mode, under each device’s Device Information tab the actual Modbus Data Address for each bit will be displayed.
- Page 10 Select Network Settings on the left portion of the screen above to modify the Ethernet parameters online. Apply the changes and they will be saved in the gateway. Gateway, SWD, and System settings may also be viewed or modified from this screen. The Network Setting page will look like the following for this example: Publication Number AD05006002E Page 10...

- Page 13 Modify the Ethernet parameters for the Ethernet master from the Basic tab. Then select the Data Exchange tab to set up polling for the SmartWire-DT gateway at IP Address 192.168.1.3. The following shows the poll messages set up in the ELC-COENETM module.
- Page 14 D304 in the ELC-PV controller and the 4 registers of output data are mapped to D310-D313 in the controller. As mentioned earlier in this document, each SmartWire-DT device displays the Modbus Data addresses for each bit in SWD- Assist. These can then be correlated to the D registers in the ELC-PV controller...
- Page 15 Any EtherNet/IP master may be used to monitor and control a SmartWire-DT system with the EU5C-SWD-EIP-MODTCP Ethernet gateway. The SmartWire- DT gateway is a slave on EtherNet/IP and a master on the SmartWire-DT network. The data for each SmartWire-DT device connected to the gateway is mapped to the Input and Output images in the gateway.
- Page 16 This is the information needed for the EtherNet/IP master to poll the EU5C-SWD-EIP-MODTCP Ethernet gateway to control and monitor the connected SmartWire-DT devices. Another piece of necessary information required by the Ethernet master is the IP address of the gateway.
- Page 17 Fill in the following: Name: EIPSWD Comm Format: Data-Sint IP Address: 192.168.1.3 Input Assembly Instance: 101, Size: 11 bytes (8-bit) Output Assembly Instance: 100, Size: 8 bytes (8-bit) Configuration Assembly Instance: 102, Size: 0 bytes (8-bit) The New Module window should look like the following: Publication Number AD05006002E Page 17...
- Page 18 Click OK to save this configuration for the EU5C-SWD-EIP-MODTCP module. Then double click the 1769-L23E-QB1 Ethernet Port LocalENB also under Ethernet to open the EtherNet/IP master port’s Property Pages. On the General Tab, enter the IP address for the CompactLogix Ethernet port: 192.168.1.2 and click Apply, then OK.
- Page 19 The I/O LED on the controller should be on solid, not flashing. This indicates that the controller is properly polling the SmartWire-DT gateway, with no errors. If the I/O LED is flashing, double click the 1769-L23E-QB1 Ethernet Port LocalENB and confirm that the online Ethernet parameters on the Port Configuration tab are correct, i.e.
