1.3.1 Important Notes on Updating Software
Please remember the following important information when updating the
software versions listed below:
TNC 320: 340 551-03 to 340 551-04 or
TNC 620: 340 560-01 to 340 560-02
If you are using linear encoders with EnDat interface or motor encoders
with EnDat interface for position measurement on your machine, you must
carry out the following step.
Move the EnDat axes to known positions before the update:
A function for monitoring the SRAM contents for consistency will be
introduced with new NC software. After the software update, all EnDat axes
will therefore display the error message S-RAM contents of axis are
invalid. At the same time, the control will display a dialog box for
confirmation, in which the current (the displayed) position of the axis is
compared with the physical (switch-off) position.
Move the axes to known positions before the update.
Write down the switch-off positions.
After the control has booted with the new software for the first time,
confirm the positions of the EnDat axes.
HEIDENHAIN recommends:
Making a backup of the control (e.g. with TNCbackup), before updating the
NC software.
Saving your current machine configuration. The configuration editor (DATA
BACKUP soft key) can be used for this purpose.
If you later want to undo the software update and return to the previous
software version, you need the saved configuration data of the old version!
Please perform the update of the NC software as described in the Technical
Manual in Chapter 2 "NC Software Exchange".
Be sure to remember the important information about the software update,
which is provided on the following pages.

Checking and saving new machine parameters:
Warning
After having installed the new NC software and rebooted the control, you
must check and confirm the new machine parameters. The MOD dialog box
appears on the screen:
Enter the MP code number 95148 and confirm your entry with the ENT key.
Press the MORE FUNCTIONS soft key.
Press the UPDATE RULES soft key.
Check the listed update rules. Each entry in the list stands for a new
parameter that was added to the system by the update.
Exit the UPDATE RULES with the END soft key.
Press the CONFIG DATA soft key.
Before the configuration editor opens, an informational window is displayed,
reporting the removal of the CfgRestorePosition machine parameter. Press
the NEXT soft key.
All new machine parameters are marked with a red exclamation point in the
configuration editor. The control indicates if certain machine parameters are
faulty. Please ignore these messages for the time being.
Important step: Press the SAVE soft key.
The Configuration data changed dialog box opens. Press the SAVE soft key
again. The new machine parameters are now automatically saved in the
*.cfg files.
Press the END soft key and exit the Machine Parameter Programming
operating mode by pressing the END soft key again.
The control then continues booting.
When the control has booted up for the first time after the software update,
the internal firmware of HSCI components must be updated.The control
displays the error message Firmware update required.
After you have acknowledged the displayed error message, the control will
start the update process automatically.
Never shut down the control while the firmware is being updated –
otherwise the control will need servicing!
After the update is finished, the control displays another message on the
screen. After you have acknowledged the message, the control will shut
down automatically. Switch off the machines and restart the control.

Note
Due to a software update regarding the evaluation of parameter
Note
MP_signCorrNominalVal (400002), you must check whether the spindle
turns in the correct direction:
Check the direction of spindle rotation, and correct it if required:
After the booting process, the control displays the error message Check the
parameter for the direction of spindle rotation!.
Acknowledge the error message.
It is essential that you check now whether the spindle turns in the correct
direction. Program a function, such as M3 or M19, and observe the direction
of spindle rotation.
If required, use parameter MP_signCorrNominalVal (400002) or
MP_signCorrActualVal (400001) to define the direction of spindle rotation
correctly, see „Defining the Traverse Direction“ on page 419.
In the first TOOL CALL after the software update, the control may display
the warning Pocket table might be inconsistent. In this case, please note
the following information:
Check the pocket table and correct it if required:
Up to now, the control allowed you to enter „0“ for zero tool T0 in the
spindle pocket. This entry is no longer permissible with the new NC
software. The control issues the warning mentioned above. The column
location for the zero tool in the spindle pocket must now be empty. Proceed
as follows to correct the pocket table:
Open the pocket table and press the EDITING ON soft key.
Delete the entry "0" for zero tool T0.

Note
The definition file of the symbolic programming interface API 3.0 has been
Note
expanded. You must perform the step described below in order for the PLC
program to be compiled successfully after the update.
Replace the apimarker.def file:
During the update of the NC software, a new version of the apimarker.def
file was automatically copied to the PLC partition of the control. Proceed as
follows:
Switch to the Programming mode of operation.
Enter the MOD code number 807667 to switch to the PLC Programming
mode of operation.
Open the File Manager with the PGM MGT key.
Switch to the PLC:\proto\plc directory.
Copy the apimarker.def file to the program directory of your PLC program.
Overwrite the existing apimarker.def file:
Please also copy the apimarker.def file to your PC as well, and add it to the
PLCdesignNT project. Otherwise, during the next transfer of PLC project
files to the control, the file might be overwritten by the old version.

Note
Please observe the following note if you
are using the HEIDENHAIN PLC Basic Program.
It is essential that you check and modify the PLC program:
The behavior of the symbolic API marker NN_ChnProgCancel (NC program
cancellation) has been changed: NN_ChnProgCancel will now be set every
time the NC program is canceled. For a normal end of program,
NN_ChnProgEnd will be set. The NN_ChnProgCancel marker remains set
during the complete Cancel cycle and beyond the program end until the next
NC program is started.
When a program is canceled, the NN_ChnProgEnd marker will not be set.
The end of program run, including the execution of a Cancel cycle, has been
reached when NN_ChnControlInOperation is reset. NN_ChnProgCancel
and NN_ChnProgEnd will be reset when NN_ChnControlInOperation is
set again.
If both NN_ChnProgCancel and NN_ChnControlInOperation are set, this
indicates that the Cancel cycle is being executed.
Module 9429 or 9320 can be used to inquire the reason for the program
cancellation.
Please check the PLC basic program and make the following changes if
necessary:

A summary of the improvements in NC software 340 551-04 and 340 560-02
is given below. For more detailed information, please refer to the Technical
Manual sections indicated in the brief descriptions given below.
Machine
Configuration
New: Search for the iTNC MP number in the configuration editor
For numerous machine parameters, the compatible iTNC MP number is
stored in the help text in the configuration editor. Up to now, it has not been
possible to search the configuration for these numbers. The search function
of the configuration editor now enables you to search for the iTNC MP
number (selection: MP number). See “Finding / Replacing” on page 236.
New: Separate parameter numbers for OEM parameters
In order for the OEM to group the parameters in the configuration editor
according to his own needs, or to make them easier to find, there is now a
separate number range for the OEM. Numbers 900000 to 999999 are
reserved for the OEM. For those parameters for which an OEM number is
defined, this number is shown instead of the HEIDENHAIN number. The
numbers are to be defined in the
%OEM%\config\layout\PlcUniqueNumbers.xml file. If the file is missing or
empty, no OEM numbers will be displayed. For more information, see „User
Parameters“ on page 257
Expanded: OEM motor table (only digital control, TNC 620)
Until now, if the OEM-specific motor table (path:
PLC:\table\motor_oem.mot) was missing, a warning was issued and the
user had to create the table himself. Now no warning will be issued. The
control itself creates a new blank table as soon as the MP_motName
(401301) parameter is edited. If the OEM motor table exists but columns are
missing, then the columns that exist in the SYS motor table will be added
when copying. The control indicates which columns were not copied.
Expanded: Saving update rules
If the user tries to exit the configuration editor without saving the changes
made by the update rules, a dialog window appears prompting the user to
save the data. The configuration editor cannot be exited until the data are
saved, see "Update rules" on page 245.
The first restart of the control after the update cannot be continued without
saving the configuration changes made by the update rules.

Operation and
technology
New: TNCguide – The context-sensitive help system of the TNC
The browser-based, context-sensitive help system TNCguide is now
available on the control. TNCguide is based on the Mozilla browser and
displays CHM help files. You can download the control's respective User's
Manual in CHM format from the HEIDENHAIN home page and transfer it to
the control. For more information and web links to TNCguide, refer to
„TNCguide – context-sensitive help system (user documentation)“ on
page 871.
New: Window manager (XFCE)
The new NC software provides a window manager (XFCE) on the control.
The window manager helps you organize the user interface and it makes the
control easier to operate. This will result in minor changes in the graphical
interface of the TNC. The operation of the control remains the same,
however. For more information, see „Window manager (XFCE)“ on
page 892
New: Software option #46 (Python OEM Process)
With the “Python OEM Process” option, the OEM can use a powerful,
object-oriented programming language within the control (PLC). Python is an
easy-to-learn script language that supports the use of all necessary
high-level language elements. Python is widely known among programming
experts.
"Python OEM Process" can be used for machine functions and complex
calculations, as well as to display special information. It provides
comprehensive possibilities for realizing user-specific and machine-specific
software solutions, e.g. special algorithms for tool calculation or custom
user interfaces for special functions. Freely definable windows up to the
size of the control screen can be displayed for visualization.
A separate documentation, additional PC tools for debugging and for the
development of user interfaces as well as example programs are available
for Python OEM Process. You can download the files from the
HEIDENHAIN FileBase free of charge: "PC Software > Python“ category.
New: Expanded status display
A new, expanded status display is available in the machine operating
modes. It is activated by the POSITION + STATUS soft key. For more
information, see the User's Manual.

Page 36
Expanded: File manager
The following improvements were made in the file manager (PGM MGT
key):
• When copying especially large files, the progress is displayed. Up to
now, the CANCEL button was unavailable (dimmed) and had no
function. Now the copying process is canceled when the CANCEL
button or soft key is pressed.
• The file manager now stores the current file sorting criteria, active file
filters and the active graphics preview in non-volatile memory, so that
these settings are still active after the control is restarted.
• Write-protected files are indicated by a red padlock in the file manager.
Now, NC programs currently being run in one of the Program Run
modes of operation are indicated by a blue padlock. This makes it
possible to distinguish whether the file is actually write-protected, or
simply cannot be changed because it is currently being executed.
Symbol Description
The file is currently being executed in one of the
Program Run modes of operation and cannot be
changed.
The file is write-protected.
Enhanced: Update of NC software
The NC software can now also be updated while it is running. The new MOD
key 231019 was therefore introduced, see "Start update while software is
running" on page 102.
Enhanced: Log
The display of the control's log was improved. The accumulated keystrokes
are now stored simultaneously with the control events in the log and are
displayed in table view.
In order to be able to track machine operation or machine conditions
systematically, detailed additional information is entered and stored
simultaneously with all important log entries, such as keystrokes, errors,
system errors or warnings, see "Error messages and log files" on page 846.
Enhanced: Display of DSP software version
After pressing the MOD key, the version number of the DSP software and
the link date are already displayed before the PLC program is compiled in the
Programming mode.
Enhanced: Display of configuration errors during start-up
If configuration errors occur during control start-up, the Error during
start-up message appears instead of Power interrupted. Also, the error
messages for the incorrect configuration data, which are triggered by the
applications, are displayed individually.

Page 37
Machine
interfacing
New: Additional data types for table columns
The control supports additional data types for columns in NC tables. The
FEED_CUT column data type applies to the cutting speed in units of m/min
or feet/min. The FEED_ROT column data type applies to the feed rate per
revolution in units of mm/rev or inch/rev. As usual, the new column data
types are listed as enumeration values of parameter MP_unit (105602) of
the configuration object CfgColumnDescription.
Enhanced: Integrated oscilloscope – Selection of symbolic operands
In the MIOTC dialog (dialog box for selecting markers, inputs, outputs,
timers and counters) in the integrated oscilloscope, symbolic API operands
can now also be selected and displayed conveniently in a list. See “Setup
for digital signals” on page 783.
New: Integrated oscilloscope – Circular interpolation test
A circular interpolation test can now be performed with the integrated
oscilloscope. See “Circular interpolation test with the integrated
oscilloscope” on page 790.
New: Test of internal EMERGENCY STOP by key code
For test purposes, an internal EMERGENCY STOP can be simulated in order
to inspect the correct wiring of the machine. The control-is-ready output is
reset. The NC and PLC are no longer operable. It is essential that you
support hanging axes before the test in order to prevent damage to the
machine in case of error. Enter the key code 6871232 under MOD to start
the test. Enter the key code again to reset the control status to "ready for
operation."
Configuring the
axes and spindle
New: Support of synchronized axes
In gantry axes, tandem tables, etc., two servo-controlled axes are coupled
so that they can move only simultaneously. The main axis is referred to as
the master, and the tracking axis as the slave. In master-slave torque
control, two motors (master and slave) are mechanically coupled. Because
of the coupling, only one position encoder is required. The motor to which
the position encoder is assigned is the master.
Software option #24 is required for synchronized axes. For more
information, see “Gantry axes” on page 520 and “Master-slave torque
control” on page 530.
New: Compensation of minor axes U, V, W
The control can now display the compensated position value of the
movements of the parallel minor axes U, V, W, and compensate them with
the principal axis. The new conversational commands PARAXCOMP and
PARAXMODE are available for this (see User's Manual).
You can use the parameter MP_parAxComp (300205) to define the default
setting for the compensation of minor axes. For more information about the
parameter, see “Parallel Axes” on page 518.
New: Operating a second spindle
The control now supports switchover between spindle motors with gear
ranges. Milling machines are often fitted with two spindles – one spindle is
used for roughing (high torque, low speed), and the other spindle is used for
finishing (high speed, low torque). The control now supports this application.
For information about the configuration of operation with alternating
spindles, see
Enhanced: Backlash compensation
If nonlinear axis-error compensation is active, MP_backLash can now be
used to activate backlash compensation in addition to the compensationvalue tables, see "Axis Error Compensation" on page 468.

PLC
programming
Enhanced: Symbolic memory interface (API 3.0) – New operands
introduced:
PLC operand / Description Ty p e
NP_ChnProgSelected
NC program selected
This marker can be used to interrogate whether an NC
program is selected in the Program Run modes of
operation. The marker is not set if an NC program is
selected from a pallet table.
NN_ChnFeedRapidTraverseActive
0: Rapid traverse is active (FMAX)
1: Rapid traverse is not active
Changed: Behavior of NN_ChnToolLifeExpired (tool life 1 expired)
The status of NN_ChnToolLifeExpired is now reset by the PLC runtime
system after the end of an NC program.
New: PLC process monitor
In the PLC programming mode you can use the MONITOR and PROCESS
MONITOR soft keys to open a status screen in which the control displays
all parallel processes, including the process for the submit queue. See
“Control of events” on page 1421.
Enhanced: BUS diagnosis
In the BUS diagnosis, the terminal names are also displayed in the tree
structure, not only in the details about a terminal. This simplifies orientation
in the circuit diagram, for example.
Enhanced: Compile PLC Program
• If the PLC program has already been compiled in the PLC Programming
mode of operation before acknowledging the Power interrupted
message, the PLC program will not be compiled again when the
message is acknowledged. This change makes it possible to observe
the PLC operands with the integrated oscilloscope during start-up of the
PLC program:
- Start the control, do not acknowledge the Power interrupted
message.
- Compile the PLC program in the PLC Programming mode of operation.
- Activate the integrated oscilloscope in order to observe the desired
PLC operands and start the measurement.
- Acknowledge the Power interrupted message now for the control to
start the PLC program.
• Now a PLC program is compiled even if the machine parameters refer
to symbolic names of PLC operands that are not defined in the PLC
program. The control issues an error message for every undefined
symbolic name and then compiles the PLC program.

Warning
A PLC program with undefined symbolic PLC operands can lead to
hazardous behavior of the machine! It is essential that you check whether
the parameters for configuring the M functions (CfgPlcMStrobe) contain
meaningful strobe definitions. The data of strobe definitions must be
mapped onto defined PLC operands.
Enhanced: Commands for string processing
Symbolic operands (B/W/D operands) can now be used for indexed access
to the string operands "S" or the PLC error and dialog files, see "Commands
for String Processing" on page 1406.
Enhanced: WATCH LIST and TRACE functions
New TYPE column: Type (M for marker, B for byte, W for word, etc.) of the
PLC operand, see "The WATCH LIST function" on page 1141.
The ADD TO WATCH LIST soft key can be used to transfer the PLC operands
of the currently highlighted line to the WATCH LIST, see "The TRACE
function" on page 1145.
Enhanced: EDIT function
The features and the operation of the editor were changed. The editor is
now a full-fledged ASCII editor. The cursor can be positioned in all directions
and line breaks can be inserted, see page 1148.
New: Moving PLC axes with the handwheel
It is now possible to assign a PLC axis to a handwheel via Module 9036. In
the El. Handwheel mode of operation, the machine operator can use the
axis keys to select a PLC axis and move it with the handwheel.
PLC modules
modified/enhanced
Enhanced: Module 9035 (Read NC Status Information)
The module now supports the status information #18 (Tilt plane is active) ,
#22 (M128, Tool Center Point Management is active), #50 to #56 (Read tool
change sequence status) as well as #1001 and #1002 (pallet machining).
See “Module 9035 Read status information (expanded)” on page 798.
Enhanced: Module 9038 (Read Status Information of Axes)
Transfer value #9 added: Axis is slave axis
For a detailed description of the module, see page 439.
Changed: Module 9145 (Actual-to-Nominal Value Transfer)
A call of PLC API Module 9145 for actual-to-nominal value transfer is now
synchronized with other positioning commands. The transfer cannot be
started while another another positioning command is pending.
A PLC position movement cannot be started while the transfer is running.
During the transfer, NC program execution is not continued after a strobe.
November 2009 1.3 NC Software 340 551-04 / NC Software 340 560-02 39
Page 40
Enhanced: Modules 9226 and 9418 (Define the Status of an Axis or
Spindle):
Comprehensive possibilities for deactivating/activating an axis without
rebooting have been provided. The improvements are described in detail in
“Writing axis information – activating and deactivating axes” on page 445.
Enhanced: Modules 9040, 9041 and 9049
The following additional axis information can be read:
7: Actual values in the reference system with backlash
8: Distance traversed in [mm] since the last lubricating pulse
9: Temperature compensation.
For the complete module documentation, see:
• „Module 9040 Reading of axis coordinates by the PLC in the format 1/
1000 (0.001) mm“ on page 441
• „Module 9041 Reading of axis coordinates by the PLC in the format 1/
10000 (0.0001) mm“ on page 442
• „Module 9049 Read position value and speed value of an axis“ on
page 440.
Enhanced: Modules 9240, 9248, 9250, 9277, 9290, 9291, 9295 and 9343
(Modules for accessing files)
The name of an OEM machine parameter from the CfgOemString
configuration object can now be transferred instead of the path name. The
transferred character sequence must begin with ">OEM." and end with the
key name from CfgOemString. The parameter value must contain the path
to the file. If no key name with the transferred path name is found, the
Modules 9248, 9277 and 9295 return the error code 62. The other modules
set the error marker to the value provided for an invalid path name.
Enhanced: Module 9247 (Searching for a Condition in a Table)
Module 9247 now accepts the SQL keyword "WHERE" in a string in order to
transfer a search condition to the module, see page 1273.
Enhanced: Module 9434 (Selecting Parameter Block)
The PLC program can now activate another parameter block while a PLC
positioning movement is being executed. A PLC positioning movement can
also be started while a new parameter block is being selected via Module
9434. In this case, the PLC program must ensure the safety of the machine.
The PLC programmer must ensure that parameter blocks containing
machine parameters that are not suitable for this drive are not selected.
Unsuitable parameter blocks can cause incorrect positioning movements
and lead to damage to the machine!
New error code 5 added:
The module was not executed, because the axis is deactivated.
For a detailed description of the module, see page 655.

The milling cycles 251 to 257 are now also available for the TNC 320 and
TNC 620. For more information, refer to the User's Manual.
Enhanced: Feed rate definitions
The two new feed rate definitions FU and FZ are supported. The functions
M136 and M137 are also supported. If M136 is active, the programmed
feed rate F is interpreted as mm/rev or 0.1 inch/rev. The feed rate is
synchronized with the current spindle speed. Now when the spindle speed
is changed with the override potentiometer, the feed rate adapts itself
automatically. M137 deactivates M136 at the end of the block.
• FU: Feed per revolution (units in mm/rev or inch/rev)
• FZ: Tooth feed per revolution (units in mm or inch per rev and tool tooth)
Enhanced: Selecting a datum table
In the Program Run, Single Block and Program Run, Full Sequence modes
of operation, the file manager (PGM MGT key) can be used to select a
datum table (*.d).
New: Execution of cycles on point patterns
The control immediately supports the execution of cycles on point patterns.
The functions SEL PATTERN, PATTERN DEF and CYCL CALL PAT are
available for this purpose. For more information, see the User's Manual.
New: Cycle 241 SINGLE-LIP DEEP-HOLE DRILLING
For detailed information on the new cycle, refer to the User's Manual.
Enhanced: Block scan
Now a block scan can be run beyond a tool change. The tool change macro
is collected in the test run and executed later when the strobes are restored.
This method also works for macros with M functions.
Enhanced: Cycle 25
Closed contours are now also allowed in the definition of a contour train with
Cycle 25.
Enhanced: Probing Cycle 425, positioning strategy was changed
The positioning strategy of touch-probe cycle 425 'Measure inside width'
was adapted to the positioning strategy of touch-probe cycle 408 'Slot
center ref point': The TNC now moves at rapid traverse for intermediate
positioning movements for large widths, to avoid unnecessary slow traverse
at the feed rate for measuring. The new parameters Q301 (Move to
clearance height) and Q320 (set-up clearance) were introduced for this
purpose.

Changed: Behavior of "INCREMENT ON/OFF" dialog box was
improved
In the Manual Operation mode, the jog increment is now activated/
deactivated immediately after the INCREMENT ON/OFF soft key has been
pressed. The jog increment can also be activated/deactivated with Module
9186 #6 via the PLC.
Changed: SPEC FCT key
The soft-key structure after the SPEC FCT was revised and expanded. For
more information, see User's Manual.
Enhanced: Tapping
A soft key for retracting the tool is offered now if the program is stopped
during tapping. For more information, see the User's Manual.
Enhanced: Block scan
Block scan now also supports point tables (*.PNT). For this, new input fields
are available after the BLOCK SCAN soft key has been pressed in the
Program Run modes of operation. In the default setting, the input fields are
hidden in the Block Scan dialog box. The fields are shown after the
ADVANCED soft key has been pressed. For more information, see the
User's Manual for the control.
New function: DIN/
ISO programming
Changed: GOTO dialog and DIN/ISO programming
The dialog box and the soft keys that appear after the GOTO key has been
pressed were revised and adapted to the present TNC contouring controls.
Now the N LINES UP/DOWN and BLOCK N UP/DOWN soft keys are also
available. This is useful because DIN/ISO programs can contain several
blocks with the same block number.
1.4 NC Software 340 554-xx (TNC 320 Programming Station)
1.4.1 Description of the New Functions
New: Automatic display of virtual keyboard

1.2 NC software 340 56x-02 Service Pack 8
1.2.1 Description of important changes
Optimized memory-space management on SYS: partition of the CFR
In rare cases, the available memory of the HEIDENHAIN system partition
SYS: on the CFR memory card became insufficient. This rendered the
control inoperable so that it could no longer be started properly.
New:
The NC software ensures that the occupancy of the SYS partition does not
reach critical values. The size of log files is limited for this purpose, for
example.
New FN function for long-term touch probe monitoring
There is a new function FN17: SYSWRITE ID990 NR102 to facilitate long-term
touch probe monitoring in OEM macros.
If the touch probe is to be monitored as long as it is in the spindle,
monitoring must be activated during the tool change with
FN17: SYSWRITE ID990 NR102=1.
Monitoring remains active (independent of probing processes, program
cancellations etc.) until it is switched off again via an OEM macro (e.g. during
the next tool change) with FN17: SYSWRITE ID990 NR102=0.
TNCguide: Configuration of conversational language changed
TNCguide, the context-sensitive user documentation on the TNC, used to
be displayed in the language set in MP_ncLanguage (101301,
CfgDisplayLanguage).
New:
Now the language for the TNCguide is specified by MP_helpLanguage
(101304, CfgDisplayLanguage).
October 2010 1.2 NC software 340 56x-02 Service Pack 8 49
Page 50
Input range of MP_maxLineGeoSearch adjusted
The number of NC blocks to be taken into account during the consistency
check of the NC program is set in MP_maxLineGeoSearch (105408,
CfgEditorSettings). If the parameter was set to a value greater than 1000,
this led, under certain circumstances, to a delay during operating mode
switchover and in the opening of large programs.
New:
Now there is an upper limit value of 999 for MP_maxLineGeoSearch.
Changes to MP_useProgAxes require a restart
MP_useProgAxes specifies whether the default axis configuration
XYZABCUVW is to be used during creation of an NC program in the
Programming mode of operation or only the axes actually available on the
machine. Previously, the control did not have to be restarted when the
parameter was changed.
New:
Changes to MP_useProgAxes now require a restart.
Changes regarding the Traversing the Reference Marks mode
If after startup of the control, before traversing the reference marks or
reference run with EnDat encoders, the error window was opened with the
ERR key, the axes were not referenced under certain circumstances.
New:
If the error window is opened before the reference run, the control now
opens the Traversing the Reference Marks mode when the error window
is exited or an operating modes key is pressed.

2.4 General Information
HEIDENHAIN contouring controls are designed for use with milling, drilling
and boring machines as well as machining centers.
The TNC 620 features integrated digital drive control and drives the power
modules through PWM signals.
Integrating the drive controller in the TNC 620 provides the following benefits:
All the software is contained centrally in the NC; this means that the
individual components of the NC, such as feed axes, spindle, NC or PLC, are
optimally matched.
High control quality, because the position controller, speed controller and
current controller are combined into one unit.
The same functions are available for commissioning, optimizing and
diagnosing feed drives as well as spindles.
The TNC 620 offers digital control for up to 5 axes and 1 spindle at spindle
speeds up to 100 000 min
The TNC 620 is based on HEIDENHAIN NCK, the software platform for the
HEIDENHAIN control family. Other controls with NCK are, for example, the
TNC 320 or the MANUALplus 620.
The MC 6110, the compact main computer of the TNC 620, takes up very little
space, as it is housed in the operating console, directly behind the integrated
15-inch TFT-display and the TNC operating panel.

panel and the PL 6xxx PLC input/output systems via HSCI (HEIDENHAIN
Serial Controller Interface). The connection of the various control components
via HSCI offers numerous benefits, including:
Simple and uncomplicated wiring
High noise immunity
Simple commissioning
Comprehensive yet straightforward possibilities for diagnostics
The TNC 620 is prepared for the connection of incremental and absolute
position and shaft-speed encoders. EnDat 2.2, which is purely digital and
compatible to version 2.1, makes it possible to very rapidly transmit highlyresolved position values over long cable lengths. An overview of EnDat 2.2:

2.4.1 HSCI interface
The individual control components communicate with each other via the HSCI
connection (HEIDENHAIN Serial Controller Interface). A connection via HSCI
is only permitted for HEIDENHAIN components that are part of the machine
tool’s control system. In addition, the HSCI connection cable may only be
installed in a protected manner (e.g. within the electrical cabinet, cable ducts).
The following features characterize the HSCI connection:
Based on standard 100BaseT Ethernet hardware
Telegrams of the HSCI connection are not compatible with the Ethernet
Line structure
Only one master in the system (MC), all other devices are HSCI slaves
Different addresses are assigned to the individual participants in the HSCI
network. The addresses are assigned dynamically during booting of the MC.
The HSCI addresses of the participants are formed from an HSCI address
(8 bits) and a device type address (6 bits).
After the machine has undergone acceptance testing, the nominal
configuration of the control is saved in the IOC file on the control’s memory
card. This nominal configuration contains the association between the devicetype address and serial number of the device to the individual HSCI addresses.
The momentary configuration is ascertained during startup of the system by
requesting the serial numbers. The momentary configuration is compared
with the nominal configuration. If there is a deviation, the machine operator is
prompted to check the configuration.
The following applies to the assignment of the HSCI address:
The HSCI address (bus address) is the result of the device's position in the
bus
The master (MC) always has the HSCI address 0
The HSCI addresses of the slaves result from their position in the bus:
• First device after the master (MC): Bus address 1
• 2.Second device after the master (MC): Bus address 2 etc.
The device type address is for internally distinguishing between connected
HSCI participants. Each device type (MC, CC, PL, MB, etc.) is assigned a type
specification, via which all HSCI participants of this type can be addressed.
More information on the connection of the HSCI components is provided
under „HSCI“ on page 120.

2.5.7 Handwheels
All handwheels are available with and without detent. For handwheels with
detent, the cogging torque prevents movements of the handwheel due to
motions or vibrations of the machine. On handwheels without detent, this is
prevented by a defined holding torque.
Handwheels with detent feature 100 detent positions per revolution, i.e. every
3.6°. The machine manufacturer defines the increment via the machine
configuration.

2.7 Software
2.7.1 Designation of the software
The control features a separate software for the NC and the PLC. The NC
software is identified with an eight-digit number.
If you press the MOD key in any operating mode, you can display the ID
numbers of the NC software and the DSP software (DSP1). An installed
service pack is shown by SPx after the ID number of the NC software.
Version The TNC 620 is shipped with the following NC software:
Standard Export Comment
340 560-xx 340 561-xx TNC 620
Due to restrictions on the export of the TNC 620, HEIDENHAIN can also
supply a special export version. This export version differs from the standard
control though the installed NC software type. HEIDENHAIN releases a new
NC software type whenever it introduces extensive new functions.
2.7.2 PLC software
The PLC software is stored on the memory card of the TNC 620.
HEIDENHAIN offers a PLC basic program you can order directly from
HEIDENHAIN or, as a registered HEIDENHAIN customer, download from the
FileBase on the Internet. With the PLC development software PLCdesignNT,
the PLC basic program can very easily be adapted to the requirements of the
machine.

2.7.3 Enabling additional axes or software options
Note
The TNC 620 is offered as a basic version with three controlled axes and a
controlled spindle. Two more controlled axes can be added as an option.
Software options can be used to adapt the scope of function of the NC
software to the respective needs and applications. See “Software options” on
page 90.
If you need additional control loops, you must enable them by entering a code
number.
SIK
(System
Identification Key)
Control loop On the basic version with 4
control loops, this
corresponds to
1st additional axis 5th control loop 354 540-01
2nd additional axis 6th control loop 353 904-01
If you wish to enable an additional axis or software options, please contact
HEIDENHAIN for the code number. HEIDENHAIN can give you the code
number after having been informed of the SIK number.
Every MC 6110 can be identified unambiguously by the SIK (System
Identification Key). You will find the SIK number on the outside of the MC 6110
housing (below the ID label) and on the SIK board.
If you replace the MC 6110, you must also replace the SIK in order to
ensure that the enabled options will also be enabled on the new hardware.

The message Option <number> has been set appears.
If the code number is correct, the enabled option is identified by the entry X in
the Active column.
Should you have ordered more than one option, and received more than
one keycode from HEIDENHAIN:
You must enable each option individually. It is possible to enter more than
one keycode in the Keycode column, but then these options cannot be
enabled. In this case the Incorrect password error message always
appears. Enter the first keycode and then press the ACTIVATE soft key. Then
enter the second keycode and press the ACTIVATE soft key again, and so on.
Press the END soft key or button. The control carries out a reset.
After entry of the master keycode (65535), all options are enabled for 14 days.
After these 14 days have expired, an error message appears, the program
currently running is aborted, and it is not possible to restart the program. In
order to avoid this error message (and the associated unintentional program
abort), the General Key must be cleared with the CLEAR soft key. Only the
options actually enabled are then available, and the General Key cannot be
entered again.

2.7.4 Upgrade functions (Feature Content Level)
Until now, each new NC software version contained error fixes as well as
expanded functions. Users who wanted only the NC software update to
eliminate the errors often felt bothered by the expanded functions. For this
reason, error fixes and expanded functions will now be handled separately
within the software.
If a new NC software is later loaded as an update onto a machine with
NC software 340 560-01, then as the default setting only the error fixes
contained will be effective. The upgrade functions will at first remain
inactive. The upgrade functions can then be enabled by entering a code
number. HEIDENHAIN can give you the code number after having been
informed of the SIK number and NC-software version.
The upgrade functions are defined as “feature content level” (FCL) in the
SIK under option #53.
The first time an NC software with upgrade functionality is installed on a
control (i.e. no FCL has been set in the SIK), then the entire scope of
functions can be used (including the upgrade functions).
The FCL is then automatically set after 100 restarts, or by entry of the code
number 0 under option #53 (see ”Enabling additional axes or software
options” on page 94), and all upgrade functions belonging to this software
version are enabled as well.
A note appears asking to confirm the installed NC software as the initial
version, or if another initial software version is to be installed.
If the FCL has already been set in the SIK of a control, then after an update
(e.g. from software 340 560-02 to -03), the new upgrade functions of the
newer software version can only be used after entry of a code number from
HEIDENHAIN under option #53 (, see page 94).
After pressing the MOD key, the current status of the FCL is displayed in
addition to the software versions.
The FCL is incremented with each new version of the NC software.
If the upgrade functions are enabled via the FCL for a software version,
then all upgrade functions of this software version and all its predecessors
are available. For example, if the FCL for version 340 560-03 is set, then all
upgrade functions from version 340 560-02 are also available immediately.
If a newer software version, e.g. 340 560-06, is simply loaded onto a control
later, then the already existing upgrade functions remain available, but the
upgrade functions of the newer version cannot be used. They must be
enabled by entering a new code number.
The feature content level is set
in the SIK:
Automatically after 100
restarts
By entering the code number
“0” under option #53

2.7.5 NC software exchange on the TNC 620
Note
Note
Note
The NC software must be exchanged only by trained personnel.
For exchanging the NC software, HEIDENHAIN provides a packed file
with the NC software. For intermediate storage, the packed file is stored
on a USB memory stick or a USB hard disk. Then it is installed on the
control from the intermediate storage medium.
HEIDENHAIN recommends making a backup of the control, for example
with TNCbackup (included in TNCremoNT), before updating the NC
software.
General
information
The setup.zip file is required for the software exchange. The installation
program of the control automatically detects the file, which must be stored
in the root directory of the data medium from which the update is run.
HEIDENHAIN recommends:
Use a USB memory stick (512 MB or larger) to exchange the software. Do
not use any memory stick with a smaller storage capacity.
A backup of the control’s most recent NC software is automatically created,
while the software is being updated. The backup file is packed and stored
on the memory stick. If the update is not completed successfully, your
previous NC software version will automatically be restored. In addition, the
complete update archive is automatically unpacked to the memory stick
before installation. The memory stick must have enough free space for the
backup and for unpacking the setup files. This is ensured by using a USB
memory stick with a storage capacity of 512 MB.
You can download the setup.zip file necessary for the update from the
“Private” area of the HEIDENHAIN FileBase (http://filebase.heidenhain.de).
You will find the file under “NC Milling TNC 620 > Software.” The file is
packed in a ZIP packet. The file name is the current NC software number.
Software updates and installation from service packs are loaded in the same
manner.
98 HEIDENHAIN Technical Manual TNC 620
Page 99
The NC software has been prepared in such a manner that when an update
Note
is performed or a service pack loaded, the PLC program, the machine
configuration or data on the PLC partition can be updated as well, according
to the OEM’s specific requirements. The OEM uses the HEIDENHAIN PC
software PLCdesignNT to add all necessary files to the setup.zip archive.
These files are copied to the appropriate locations on the control during an
update.
For detailed information on how to add OEM specific files to the setup
packet, refer to the online help for PLCdesignNT under “Generate Machine
Setup.” The support necessary for this from PLCdesignNT will be available
starting from version 2.3.
November 2009 2.7 Software 99
Page 100
Procedure for
exchanging the NC
software
To install an NC software update, proceed as follows:
If the machine is running, shut down the control by pressing the OFF soft
key.
Switch off the machine.
If the new NC software is stored on a USB memory stick or a USB hard disk,
connect the storage medium to a free USB socket (X141 or X142) on the
MC 6110.
Switch the machine back on again.
When the screen turns blue while the control is starting up, press the DEL
key on the operating panel repeatedly. You may not hold down the DEL key.
The control interrupts the boot process and a login message of the
HEIDENHAIN operating system will be displayed:
Enter 1 or 049866931 for “Username”. If a USB keyboard is connected to
the control, you can also enter update as an alternative.
Press the ENT key or the RETURN key on the external USB keyboard.
The control starts the HE menu. The following window appears on the
screen:
