TNC Model, Software and Features
This manual describes functions and features provided by TNCs as of
the following NC software numbers.
The suffix E indicates the export version of the TNC. The export
versions of the TNC have the following limitations:
Simultaneous linear movement in up to 4 axes
HSCI (HEIDENHAIN Serial Controller Interface) identifies the new
hardware platform of the TNC controls.
HeROS 5 identifies the operating system of HSCI-based TNC controls.
The machine tool builder adapts the usable features of the TNC to his
machine by setting machine parameters. Some of the functions
described in this manual may therefore not be among the features
provided by the TNC on your machine tool.
TNC functions that may not be available on your machine include:
Tool measurement with the TT
Please contact your machine tool builder to become familiar with the
features of your machine.

Feature content level (upgrade functions)
Along with software options, significant further improvements of the
TNC software are managed via the Feature Content Level (FCL)
upgrade functions. Functions subject to the FCL are not available
simply by updating the software on your TNC.
Upgrade functions are identified in the manual with FCL n, where n
indicates the sequential number of the feature content level.
You can purchase a code number in order to permanently enable the
FCL functions. For more information, contact your machine tool
builder or HEIDENHAIN.
All upgrade functions are available to you without surcharge
when you receive a new machine.
