4 Creating a planned SmartWire-DTSmartWire-DT configuration in SWD-Assist4.3 Selecting a communications protocol36 SmartWire-DT Gateway EU5C-SWD-EIP-MODTCP 08/17 MN120003Z EN www.eaton.comSpecifying the device name for the SmartWire-DT modulesJust like with the gateway, device names are also used for SmartWire-DTmodules in the SWD-Assist planning program. A device name based on themodule's type and position in the SWD line will be suggested by default.These device names are used to identify the modules and must be unique.They are used when generating symbolic names for I/O data.The device name must be unique, i.e., it cannot be used for any other Smart-Wire-DT modules. The maximum permitted length is 24 characters. Thename can contain letters, numbers, and underscores (_). Vowels like "ä", "ö"are not permissible.Figure 19: Specifying the device name for a SmartWire-DT module in SWD-Assist4.3 Selecting a communications protocolThe gateway can work with either the EtherNet/IP orModbus/TCP field busprotocol in order to exchange data with higher-level PLCs.The default field bus protocol is EtherNet/IP.The protocol that should be used is selected either through the web interfaceor in the project with SWD-Assist.▶ Open the "Device parameters" tab and select the field bus protocol youwant using the "Mode" setting.￫ To open the online Help function, press the F1 function keywhile working with SWD-Assist.
