You can create a LON device interface (XIF) file for a LON device that you have created. LON XIF files are typically provided by the device manufacturer and created by the development tools used to create the devices. There are many development tools available for creating LON devices. Three of the most popular tools are the FT 6050 EVK, the ShortStack SDK, and the IzoT SDK. All three of these tools create LON XIF files which are compatible with the SmartServer. Refer to the documentation for your LON development tool to find the location of the LON XIF files generated by the tool.
