• Application image files (.apb extension). The application that determines how a device functions.
• External interface files. The logical interface to a device. It can either be a device interface file
(.xif extension) or a device template (.xml extension).
• Resource files. Defines the components of the device interface, including network variable types,
configuration property types, format types, and functional profiles implemented by the device
application.
Copying Application Image Files
The application image is a file provided by the device manufacturer that determines how a device
functions. It consists of the object code generated by the Neuron C compiler and includes other
application-specific parameters such as self-identification data and program ID string.
To copy an application image to the SmartServer, follow these steps:
1. Verify that you have the correct user name and password to access the SmartServer via FTP and
that FTP access is enabled on your SmartServer. To do this, follow these steps:
a. Right-click the SmartServer icon, point to Setup, and then click Security on the shortcut
menu. Alternatively, you can click Setup and then click Security. The Setup – Security
Web page opens.
b. In the General property, check the FTP/Telnet User Name and FTP/Telnet Password
properties.
c. In the Service property, verify that the Enable FTP check box is selected.
2. In the browser of an FTP client such as Microsoft Internet Explorer 7, enter the FTP URL of your
SmartServer (ftp://192.168.1.1, for example).
3. Enter the FTP/Telnet user name and password for accessing your SmartServer via FTP.
4. Use FTP to access the root/lonworks/import directory on the SmartServer flash disk.
5. Upload the application image (.apb extension) from the location where it is saved, which could be
a shared network drive with read/write permissions, to the root/lonworks/import folder on the
SmartServer flash disk. Note that you cannot copy a file from one SmartServer and directly paste
it into another.
Copying External Interface Files
The external interface file (XIF) is a file provided by the device manufacturer that defines the logical
interface for a device. The file can be a device interface file (.xif extension) or a device template file
(.xml extension). The XIF specifies the number and types of functional blocks, and the number, types,
directions, and connection attributes of data points. The program ID field is used as the key to identify
each external interface. Each program ID uniquely defines the static portion of the interface.
• To copy a device interface file (.xif extension) to the SmartServer, follow the steps outlined in the
previous section, Copying Application Image Files.
• To copy a device template file (.xml extension) to the SmartServer, follow the steps outlined in the
previous section, Copying Application Image Files, except that in step 4, access the
root/config/template directory on the SmartServer flash disk, and then in step 5, copy the device
template to that directory.
Note: If you upload any XIFs to the SmartServer, you should also upload any used user-defined types.
Copying Resource Files
A resource file defines the components of the device interface, including network variable types,
configuration property types, format types, and functional profiles implemented by the device
application. Resource files allow for the correct formatting of the data generated or configured by the
