4 Creating a planned SmartWire-DTSmartWire-DT configuration in SWD-Assist4.4 Ethernet parameters tabSmartWire-DT Gateway EU5C-SWD-EIP-MODTCP 08/17 MN120003Z EN www.eaton.com 37Figure 20: Selecting the field bus protocol in SWD-Assist:left - Ethernet/IP; right - Modbus/TCPThe field bus protocol you select will affect the way I/O allocation lists arecreated for the PLC programming environment during the planning phase.EtherNet/IPIf you select EtherNet/IP as the mode, the I/O addresses (tags) will bedefined according to the agreements for EtherNet/IP. The format of theexport file created in SWD-Assist is designed to enable you to import these I/O identifiers directly into the RSLogix 5000 PLC programming environment.Modbus-TCPIf you select Modbus/TCP as the mode instead, the I/O data will be mappedto the relevant register data structure as per the specifications for Modbus/TCP. The address assignments will then be provided in an export file so thatthey can be worked with further.4.4 Ethernet parameters tabThe EU5C-SWD-EIP-MODTCP gateway will communicate with the higher-level PLC via the Ethernet interface regardless of the field bus protocol youselect. The gateway comes with the following default settings:IP address: 192.168.1.254Subnet screen: 255.255.255.0Default gateway:192.168.1.1▶ Open the "Ethernet parameters" tab.▶ Change the setpoint values for the field bus address as necessary.￫ If you change the field bus protocol (EtherNet/IP or Modbus/TCP), you will have to load the planned SmartWire-DT configura-tion into the gateway once again. The change will only takeeffect after the gateway is restarted.
