The 1-Wire Tag file specification as defined here can reside in a file on the 1-Wire sensor itself (physical) or in another file system such as on the master (local) or in a database on a server (remote). When the file is located in the memory of a 1-Wire device in the 1-Wire cluster (physical) it must be in the form of a 1-Wire File Structure file. The file can reside in any normal memory 1-Wire device such as the DS1993, DS2406, or DS2433. The specification for the 1-Wire File Structure can be found in the Dallas Semiconductor Application Note 114, 1-Wire File Structure.
