Data backup
We recommend saving newly written programs and files on a PC at
regular intervals.
HEIDENHAIN provides a backup function for this purpose in the data
transfer software TNCremoNT. Your machine tool builder can provide
you with a copy of TNCBACK.EXE.
You additionally need a data medium on which all machine-specific
data, such as the PLC program, machine parameters, etc., are stored.
Please contact your machine tool builder for more information on both
the backup program and the floppy disk.
Take the time occasionally to delete any unneeded files so
that the TNC always has enough memory space for
system files (such as the tool table) .
