Update Information No. 8
In mid February 1996 software version 17 was released for the NC software types 260 02 and 280
49, and for the newly introduced software types 260 060 (for 1 MB EPROMs) and 280 610 (for 2 MB
EPROMs). The new software types were introduced for the Polish conversational language.
Software version 17 contains the following additions:
• The software now supports the new handwheel HR 410.
The HR 410 is a portable electronic handwheel with:
Keys for selection of five axes
Keys for traverse direction
Keys for three pre-programmed feed rates for latched traverse
One key for actual-position capture
Three keys for machine functions determined by the machine manufacturer
Two permissive buttons
Emergency stop button
Magnetic holding pads
With MP7640 = 6 you can activate the functions for the HR410 handwheel.
MP7645.0 determines whether the keys on the handwheel are assigned to the NC or the PLC.

Update Information No. 5
For NC software types 260 02 and 280 49, software version 13 was released in mid-June1994,
software version 14 at the end of June, and software version 15 at the beginning of July.
Software version 13 contains the following enhancements:
The input range for machine parameter MP1350 (type of reference mark approach) was
expanded. An input value of 3 selects encoders with distance-coded reference marks, and
thedirection of traverse reverses when the trip dog for the reference end position is crossed.
Data transfer in blockwise mode (ACK/NAK protocol) could be interrupted if the control
characters STX or ETB were transmitted incorrectly. Since the TNC did not know the cause of
the interruption, it sends NAK (after a delay in which no further data are transferred) if a block
was not completely recognized due to a faulty STX or ETB.
If ACK is not received within a certain time, the error message TRANSFERRED DATA
INCORRECT N is generated.
If bit 3 in machine parameter MP7641 is set, the electronic handwheel is selected in each
operating mode (initially before REF traversing) to be able to interrogate the inputs of the
handwheel keys (except axis keys) in the PLC. The axis keys on the handwheel and the
handwheel impulses do not become active until handwheel mode is selected. After an error the
handwheel is not selected again until the handwheel key is pressed.
If the operating voltage of the control is outside the limit values, the blinking error message
PROCESSOR CHECK ERROR M is displayed.
The input range of machine parameter MP4220 has been expanded to 0 ... 65535.
The memory for the executable PLC program has been increased from 28K bytes to 32K bytes.
The value for the analog voltage of the analog input at connector X8 is transferred to word
W392.
The meaning of machine parameter MP7225 (automatic block generation with the capture
actual position key or with PLC marker M2829) has been changed as follows:
MP7225 = 1 : Block generation with the capture actual position key
MP7225 = 2 : Block generation with PLC marker M2829
MP7225 = 0 : No block generation
The resolution of the feed rate display depends on the programmed feed rate:
Feed rate ≤ 31 999 mm/min (previously 29 999 mm/min): display step 2 mm/min
Feed rate > 31 999 mm/min (previously 29 999 mm/min): display step 20 mm/min
Software version 14 was released to correct the following error:
If a STOP and an M function for PLC positioning were executed in one NC block, in the
following block an M function that becomes effective at the beginning of the block (e.g., M3)
was not executed!
7/94 TNC 360/TNC 335 Update Information No. 5 1-1
Software version 15 was released to correct the following error:
### If, in an OEM cycle that was run from the EPROM, the feed rate was defined via Q parameter,
a greatly excessive feed rate was ouput.
1-2 TNC 360/TNC 335 Update Information No. 5 7/94
Update Information No. 4
In late February 1994, software version 12 was released for the NC software 260 02 and 280 49.
Note:
In software version 11, the deceleration ramp is too flat when the feed rate is changed at constant
contour transitions during operation with feed precontrol. This error was corrected in software
version 12.
Software version 11 must be replaced by software version 12!
No new features were introduce in software version 12.
2/94 TNC 360/TNC 335 Update Information No. 4 1-1
Update Information No. 3
Software version 11 for software types 260 02 and 280 49 was released at the end of January 1994.
Software version 10 was not released for general distribution.
The following improvements were made since version 9:
Machine parameter 7411 defines whether during execution of the TOUCH-PROBE block the
•
current compensation values for probe length and radius should be taken from the central tool
file or from the calibration process.
MP7411 = 1 : Probe length and radius values from the tool file
MP7411 = 0 : Probe length and radius values from the calibration process
MP 7411 is also effective for tool length compensation in the digitizing cycles. This machine
parameter was already available in version 08, but it was not documented.
Machine parameter MP7225 was introduced for automatic generation of NC blocks in the
•
PROGRAMMING AND EDITING mode. With the "actual position capture" key (teach-in) it is now
possible to generate a positioning block in plain language dialog (not in ISO mode) with a
maximum of 3 axes and without feed rate, radius compensation or M-functions. This positioning
block is inserted below the currently addressed block in the selected NC part program. The
current actual position values become the nominal position values. The axis is selected in the
dialog "AXIS SELECTION =" in the MOD operating mode. Here up to 3 out of 4 axes can be
selected by pressing the corresponding axis keys.
MP7225 = 1 : Block generation with the actual-position-capture key (teach-in)
MP7225 = 2 : Block generation with the actual-position-capture key or with the PLC marker
M2829 (the marker is reset by the NC)
MP7225 = 0 : No block generation or axis selection possible.
If the machine parameters are erased, the RS-232-C/V.24 interface is now preset to FE mode.
•
PLC inputs I160 to I175 (HR 332 handwheel) now generate signal edges. The positive edge is
•
assigned to markers M1660 to M1675, the negative flank to markers M1860 to M1875.
If machine parameter MP7641, Bit 2 = 1, the interpolation factor for the handwheel can be set
•
both from the keyboard as well as from PLC module 9036. If Bit 2 = 0, the machine parameter
functions as before (input either from the keyboard or from PLC module 9036).
The NC saves the code number entered in the MOD mode in Doubleword D276.
•
Machine parameter MP810 defines the modulo value for reducing the position values of the
•
auxiliary axes. Machine parameter MP7470 has no effect on auxiliary axes. Rotary axes as NC
axes are always reduced to the range 0° to 359.999°. Machine parameter MP810 was already
available in version 08, but it was not documented.
1/94 TNC 360/TNC 335 Update information No. 3 1-1
The new PLC module 9124 makes it possible to set a feed rate override value for secondary
•
axes. The override value can lie between 0% and 100% (resolution 0.01 %) and must be
transferred as a whole number (0 to 10 000). It can be set before the beginning of a movement
or during the movement of an auxiliary axis. If the control is reset, the NC presets an override
value of 100%.
Call :
PS B/W/D/K <Axis> (0..3 for X/Y/Z/4)
PS B/W/D/K <Override value> (0..10 000)
CM 9124
PL B/W/D <Error code>
0: Override was set
1: Invalid axis was entered
2: Axis is not defined as auxiliary axis
3: Override value is invalid
Error status after call: M3171 = 0 : Override was set
= 1 : Error condition see above
If more than one of the PLC modules 9120/9121/9123 for controlling the movement of auxiliary
axes is called within one PLC scan, only the last called PLC module is executed. The module
9124 can be called in addition to the above modules within one PLC scan, but it will always
become effective after the other module.
In PLC module 9036 (transferring PLC status information to the NC) the interpolation factor can
•
be set for all axes by transferring the value 4 or 5.
The PLC can inhibit the reference pulse for specific axes through Word W608 (bit-
•
coded,....4zyx).
Bit = 1 : Reference pulse is not evaluated
Bit = 0 : The next reference pulse is evaluated
By setting marker M2615 the reference mark of the spindle is evaluated again. The marker is
•
reset by the NC.
Marker 2510 fixes the spindle potentiometer setting at 100%. Marker M2511 has the same
•
effect on the feed rate potentiometer.
CC blocks in OEM cycles are effective only locally and are not transferred into the calling
•
program.
1-2 TNC 360/TNC 335 Update information No. 3 1/94
Update Information No. 2
In earl September 1993 the software version 09 was released for the software types 260 02 and
280 49.
The new version contains the following changes:
If marker M2612 (Suppress position exchange in the tool table) is set before a T strobe is set
•
(M2046), the position numbers are not exchanged. The PLC acknowledges the T strobe without
having exchanged in the tool magazine and resets the PLC marker M2612. The new tool
number is shown inverted and the associated tool data (length and radius) are activated. The
tool number is shown inverted in the status display until the tool has physically been changed. If
the control is switched off and on in this condition, the last exchanged tool becomes active
again.
During execution of cycle 13 (spindle orientation) the NC sets the new marker M2408. This
•
marker can be evaluated by the PLC for the spindle orientation and should afterwards be reset
by the PLC.
9/93 TNC 360/TNC 335 Update information No. 2 1-1
Update Information No. 1
1 Software
In July 1993 the following software was released:
260 02x 08 for insertion of 1M byte EPROMs
and 280 49x 08 for insertion of 2M byte EPROMs
The software numbers 280 49x 01 to 07 were not delivered. The new software version became
necessary because new logic units can also accommodate 2M byte EPROMs (see below in Section
2 "Hardware").
The new software version contains the following changes:
The PLC can limit the maximum feed rate through the doubleword D596. In order to ensure
•
compatibility to previous PLC programs the doubleword D596 is preset with the value
300 000 mm/min after control switch-on or after interruption of the PLC run.
The new feed rate is effective immediately!
The doubleword D596 has no effect with the new cycles "Tapping" (Cycle 2) and "Rigid Tapping"
(Cycle 17).
In the newly introduced machine parameter MP60, axes can be defined as auxiliary axes.
•
These axes cannot be moved by an NC program. They are controlled exclusively by the PLC.
All auxiliary axes work independently of each other. Auxiliary axes always move in trailing
mode. The following modules are available for the PLC to control the axes:
Module 9120: Positioning of auxiliary axes
Module 9121: Stopping the auxiliary axes
Module 9122: Status inquiry of auxiliary axes
Module 9123: Traversing the reference point of an auxiliary axes
Spindle orientation can be suppressed at the beginning of Cycle 17 "Rigid Tapping" with
•
machine parameter MP7160. At the beginning of the cycle, the spindle voltage is decelerated
with the ramp from MP3410.1 to the value 0 volts.
In this case it is not possible to cut into the same thread several times!
Up to 20 NC "tool def" blocks can be read-in during blockwise transfer without central tool
•
memory, whereby the tool def block must be read-in before the associated "tool call". When a
"PGM call" NC block is read-in or when a user cycle is called, the NC blocks with "tool def" are
considered up to the above mentioned limit and provided that the proper order is followed. A
violation of these preconditions releases the error message "TOO MANY TOOLS".
9/93 TNC 360/TNC 335 Update information No. 1 1-1
If bit 2 is set in machine parameter MP7300, the last inserted (programmed) tool is
•
automatically activated during switch-on.
By setting the static PLC marker M2612 the PLC can now prevent the exchange of pocket
•
numbers in the central tool memory during a P output.
Function FN19 was introduced, with which two numerical or Q parameter values with an
•
accuracy of 1/1000 (i.e., three places after the decimal point) are transferred into the PLC
doublewords D280 and D284. A value of 2.5, for example, is filed in the doublewords as 2500.
The unit of measure of the calling NC program is set in marker M2150 (millimeter=0/inch=1).
During transfer the NC sets the strobe marker M2149. The transfer must be acknowledged by
the PLC with the marker M2611.
The number of PLC labels was increased to 1024.
•
Marker M2614 was introduced. Setting this marker blocks the output of PLC functions
•
(M/S/T/Q output) by the NC. The marker is set and reset by the PLC; it is read by the NC.
Marker M2827 was introduced. It is set by the PLC and causes the following behavior in case
•
of an external EMERGENCY STOP and erasable positioning error:
Machining is not aborted ("control in operation" symbol off, strobe signal reset). Instead,
machining is merely interrupted as in an NC STOP (control-in-operation symbol blinks). This
permits machining to be resumed with NC START after the error has been corrected. This
marker functions only for the output of M/S/T/Q strobes.
Now a maximum of 32 Q parameters can be transferred for user cycles. To do this, the 'DLG-
•
DEF' or 'DLG-CALL' blocks must be programmed several times in the user cycle, whereby in
the third DLG block only the first five entries can be evaluated.
The following Q parameters were introduced:
•
Q114 current tool length
Q115 to Q118 measured values of the 4th axis after a programmed probing cycle
The type of tool compensation (R0/RR/RL/R+/R-) is stored in Q parameter Q123:
•
Q123 = 0 means R0
= 1 means RR
= 2 means RL
= 3 means R+
= 4 means R-
Application as positioning module:
•
If machine parameter MP 4010 = 1 is programmed (PLC program from RAM), no machine
parameters will be taken from the PLC EPROM when the positioning module is switched on. If
the CRC sum of the machine parameters is incorrect they will be taken from the PLC EPROM.
1-2 TNC 360/TNC 335 Update information No. 1 9/93
The software now supports PLC subprograms stored in the PLC-EPROM (translated PLC
•
code). With the PLC.EXE programming software from HEIDENHAIN such programs can be
written and on an external computer and filed in the PLC EPROM.
The incremental jog positioning can be activated or deactivated (dialog "JOG-INCREMENT: ...")
•
in the 'ELECTRONIC HANDWHEEL' operating mode by pressing the 'ELECTRONIC
HANDWHEEL' key, provided that marker M2498 is set.
In the 'PROGRAMMING AND EDITING' operating mode the electronic handwheel can be used
•
to move the axes, provided that in machine parameter MP7641 bit 1 = 1. The interpolation
factor (regardless of handwheel model) and the handwheel axis (for HR130) can be change
only in the 'ELECTRONIC HANDWHEEL' operating mode. A handwheel axis, once chosen,
remains in effect even when the operating mode is changed.
Simultaneous operation of the handwheel interface and the RS-232-C interface at differing
baud rates (38 400 and 19 200 baud) results in the error message "BAUD RATE NOT
POSSIBLE".
The current feed rate in mm/min is now available in the PLC.
•
Module 9150
•
During an active M/S/T output the PLC can use module 9150 to define an NC block, which is
then executed after the M/S/T strobe is acknowledged, before the control continues the NC
program. An NC block can also be defined if no program is being run. The block is then
executed immediately.

Module 9120
•
Positioning an auxiliary axis
The positioning of an axis is started by presetting a target position (in the reference system), a
feed rate and a flag register. The axis is positioned without regard to other processes in the
control. There is no contour interpolation with other axes.
Conditions:
The given axis must be activated via MP10 and configured as an auxiliary axis via MP60.
The values for rapid traverse, analog voltage for rapid traverse, acceleration, etc., must be
properly set in the machine parameters.
For axes with automatic reduction (modulo value in MP810.x) the axis is always moved in the
shortest direction to the target position, unless the target position is entered as an incremental
value.
There is no checking for violations of the limit switch ranges!
The axis must be stationary. If the axis is already moving, the positioning must be terminated
beforehand with module 9121.
If the axis was in the reference point traversing mode, this state is canceled. The positioning
always builds on the momentary counter contents.
If the modules 9120, 9121 and 9122 are called several times during a PLC scan, only the last
instruction is executed.
If a "positioning error" status was set in this axis it is erased.
Potential errors:
A non-existent axis was transferred.
An axis was transferred that was not identified as an auxiliary axis in MP10 and MP60.

PLC MODULE 9121
•
Stopping a positioning with an auxiliary axis
A positioning started beforehand with modules 9120 or 9123 can be canceled at any time with
module 9121.
Conditions:
The given axis must be activated via MP10 and configured in MP60 as an auxiliary axis.
If modules 9120, 9121 and 9122 are called several times for the same axis during a PLC-scan,
only the last instruction will be executed.
Potential errors:
A non-existent axis was transferred.
An axis was transferred that was not configured in MP10 and MP60 as an auxiliary axis.
The given axis is already stationary.
Call:
PS B/W/D/K <Axis> (0 to 3 for X/Y/Z/4)

PLC MODULE 9122
•
Inquiring the status of an auxiliary axis
For a certain axis a bit-coded status word is transferred that contains information on the
momentary operating state of this axis.
Conditions:
Status changes causes by commands that the PLC sends to control the auxiliary axes
(modules 9120, 9121, 9123) are not recognized until the next PLC scan.
After switch-on, bit 1 (axis over reference point) is erased.
It is possible to position the axis without traversing the reference point first.

Bit 4: 1= A positioning error has occurred
Error status after call: M3171 = 0: Status was transferred
= 1: Faulty execution
PLC MODULE 9123
•
Passing over the reference point of an auxiliary axis
The module starts positioning in a preset direction, which continues until a reference point is
found or the positioning is canceled with module 9121.
Conditions:
The given axis must be activated via MP10 and configured as an auxiliary axis via MP60.
The values for rapid traverse, analog voltage for rapid traverse, acceleration, etc., must be set
in the machine parameters.
There is no checking for violations of the limit switch ranges!
The axis must be stationary. If the axis is already moving, the positioning must be canceled
beforehand with module 9121.
The feed rate override is not included in the calculation.
The state "reference point not yet traversed" is set for the axis.
A reference point that already exists in this axis is erased, but not the numerical value of the
axis. This is not reinitialized until the reference point is found.
If modules 9120, 9121 and 9122 are called several times during a PLC scan, only the last
instruction is executed.
If a "positioning error" status was set in this axis it is erased.
The positioning is stopped as soon as the reference point is reached. Since the axis must
decelerate before it can stop, it comes to rest behind the reference point in the direction of
motion.

2 Hardware
The part numbers of the LE 360C logic units that can accommodate 2M byte EPROMs are:
Id.-Nr. 270 641 3x for BE 212
Id.-Nr. 270 642 3x for BF 110
The 2-M byte EPROMs occupy only the sockets IC-P1 and IC-P2. IC-P3 and IC-P4 remain vacant.
The jumper located next to IC-P1 should then be inserted in the setting 2M!

PLC outputs
The logic unit contains the electronics for both the NC and the PLC sections of the control.
The common data area contains the machine parameters and the PLC markers and words. The
machine parameters define the hardware-configuration of the machine (ranges of travel,
acceleration, number of axes etc.). The PLC markers and words are used for the exchange of
information between the NC and the PLC.
