XIF files are files that define the external interface for one or more LONWORKS devices. The external interface includes the device's self-documentation information, the number of address table entries, the number of message tags, and the number, types and directions of network variables.

There are two benefits to using external interface files. First, an external interface file may include information that is not included in a device such as network variable names. Second, an external interface file can be used during network engineering when the device is not accessible from the network engineering tool.

You can read more about the external interface by clicking on the External Interface Reference Guide, below. You will need Acrobat Reader to use the file. Or you can download the actual external interface file by clicking on External Interface File. You will need WinZip to open the text file.

There are two sets of files to choose from. The serial number on your Intelli-Fin will determine which set of files you need. If the serial number on your Intelli-Fin is less than I03H0015780, you need the first set of files.
