December 2001
The hard disk of the TNC is divided into three partitions:
User-specific data such as NC programs, tool tables, datum tables, and pallet
tables.
Your OEM-specific data such as system files, PLC programs, machine
parameters, help files, PLC dialogs, PLC error tables, compensation value
tables and OEM cycles. The PLC partition is visible only after you have entered
the code number 807667.
As a machine tool builder, you are concerned primarily with the PLC partition.
System-specific files such as system files, NC dialogs, HEIDENHAIN cycles,
etc. The SYS partition is not visible and cannot be selected.
Warning
Alterations in the system partition can impair proper function of the TNC!
As of NC software 280 476-06, hard disks with more than 3.25 GB are
supported. In a hard disk with 3.25 GB the partitions are divided as follows:
Partition

TNC
User data
PLC
OEM data
SYS
System data
If the hard disk has more than 3.25 GB, the SYS partition receives the rest, up
to a maximum of 2 GB. If there is still space available, it is used for the PLC
partition up to a maximum of 2 GB. The rest is used by the TNC partition.
