Notes on data management

The TNC stores the saved data in the file TNC:\table\DATA450.KD.
This file can be backed up on an external PC with TNCREMO, for
example. If the file is deleted, the stored data are removed, too.
If the data in the file are changed manually, the data records can
become corrupted so that they cannot be used anymore.
If the TNC:\table\DATA450.KD file does not exist,
it is generated automatically when Cycle 450 is
executed.
Do not change stored data manually.
Make a backup of the TNC:\table\DATA450.KD file
so that you can restore the file, if necessary (e.g. if
the data medium is damaged).
