ls Data backup TNC 426, TNC 430
We recommend saving newly written programs and files on a PC at
regular intervals.
You can do this with the free backup program TNCBACK.EXE from
HEIDENHAIN. Your machine tool builder can provide you with a copy
of TNCBACK.EXE.
In addition, you need a floppy disk on which all machine-specific data,
such as 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.
Saving the contents of the entire hard disk (up to 1500 MB)
can take up to several hours. In this case, it is a good idea
to save the data outside of working hours, (e.g. overnight),
or to use the PARALLEL EXECUTE function to copy in the
background while you work.
