1 – 6 HEIDENHAIN Service Manual for Data Interfaces
2 General Information on the Data Interfaces
2.1 RS-232-C/V.24 Interface
RS-232-C is the designation of a serial interface for transfer rates of up to 19,200 bps based on
the American EIA standard of the same name. Data transfer is executed asynchronously, with a
start bit before each character and one or two stop bits after each character.
The interface is designed for transmission distances of up to 30 meters.
The RS-232-C interface has been adopted with slight modifications and introduced into Europe
as the V.24 interface. The relevant German standard is DIN 66020.
2.1.1 Hardware
The physical connection between two RS-232-C/V.24 interfaces is an asymmetrical line, i.e. the
common ground connection between transmitter and receiver is used as a return wire.
Physical connections:
2.1.2 Signal levels
With the RS-232-C/V.24 interface one must differentiate between two different signal lines and
their levels.
Data lines:
The data signals are defined as being logical one (MARK) over the range –3 V to +15 V and
logical zero (SPACE) over the range +3 V to +15 V.
Control and signal lines:
These signals are defined as being ON (High) over the range +3 V to +15 V and as OFF (Low)
over the range –3 V to –15 V.
For all of the signals, the voltage range from –3 V to +3 V is not defined as a logic level and can
therefore not be evaluated.
June 2011 2 – 7
2.1.3 HEIDENHAIN data transfer software
TNCremoNT is a software package for communication between PCs and HEIDENHAIN controls
or programming stations.
Data transfer is carried out over the Ethernet network or the serial interface.
TNCremoNT can be run on all common personal computers.
A version of Windows 2000, XP, Vista or 7 must be used as operating system.

2 – 8 HEIDENHAIN Service Manual for Data Interfaces
2.2 RS-422/V.11 Interface
As the features of the V.24/RS-232-C interface are limited, the V.11/RS-422 interface was
developed. This interface is also standardized, but operates symmetrically.
The RS-422/V.11 serial interface is suitable for data transfer rates up to 10 Mbps.
At a baud rate of 38,400 bauds, data can be transferred over 1 km cable.
2.2.1 Hardware
The V.11/RS-422 standard operates with differential voltages. This offers the advantage that
interferences act on both signal lines equally and simultaneously over the transmission distance.
As the receiver only evaluates the differential voltages of the two signal lines, interferences are
not relevant. By this means, considerably longer lines can be installed, and the transfer rate is
much higher, as interferences are limited.
Physical connections:
June 2011 2 – 9
2.2.2 Signal levels
With the V.11/RS-422 interface the signals are both transmitted and received as differential
voltage.
A positive differential voltage means a logical zero (OFF), a negative differential voltage means
a logical one (ON).
Differential voltages between
U
= 2 V and U
dmin
= 5 V are output; the control detects the differential voltages
dmax
between
U
= 0.2 V and U
dmin
= 6 V as logically defined levels.
dmax
2.2.3 HEIDENHAIN data transfer software
See chapter 2.1.3
2.3 Ethernet
Ethernet technology is most frequently used in local networks. It was developed by Digital
Equipment, Intel and Xerox in 1982. Ethernet operates at a data transfer rate of up to 100 Mbps
(Fast Ethernet); the hardware versions most frequently used - such as 10Base2 (Thin Ethernet,
Cheapernet), 10Base5 (Thick Ethernet, Yellow Cable) or 10BaseT (Twisted Pair) - operate at
10 Mbps. They differ in price, routing complexity or network topology, but not in the method of
accessing media.
The data transfer rate strongly depends on the amount of traffic at the time on the net.
Realistic values: NC program up to 200 Kbps
ASCII file up to 1 Mbps
2 – 10 HEIDENHAIN Service Manual for Data Interfaces
2.3.1 Hardware
2.3.2 Signal structure
The integrated Ethernet expansion card provides you with both the 10Base2 (BNC) port and the
10BaseT (twisted pair). You can only use one of the two connections at one time. Both
connections are electrically isolated from the control electronics.
Connection and wiring diagrams see chapter 7.2, pin layouts see chapter 3.2.
X26 Ethernet interface, BNC connection (coaxial cable, 10Base2)
The 10Base2 connection is also commonly known as ThinEthernet or CheaperNet.
You connect the TNC with your network via BNC-T connector. The maximum cable length is
185 m (coaxial cable). The network topology is a linear bus. The "open" ends of the bus must be
terminated with terminating resistors.
X25 Ethernet interface, RJ45 connection (10BaseT)
The twisted-pair cable of the 10BaseT connector may be either shielded or non-shielded.
Maximum cable length: non-shielded: 100 m
shielded: 400 m
The network topology is a star connection. This means a central node establishes the connection
to the other participants.
Ethernet frames are transferred in Manchester code which is a self-clocking code. The
synchronization or the transfer of a transmit clock pulse is executed such that each bit is
transmitted inverted in the first half of the transfer period, i.e. the bit rate is half the baud rate.
A data rate of 10 Mbps results in a bit time of 100 ns. Carrier detect (activity on the cable) is
indicated by the presence of signal level changes. If the signal level does not change in a bit time
interval between 0.75 and 1.25 after the last transition, no carrier is detected (see figure).
The network settings of the TNC are described in the Technical Manual and in chapter 7
(Ethernet) of this Service Manual.
June 2011 2 – 11
2.3.3 Connecting the TNC to data networks
Note
The HEIDENHAIN control models TNC 426/TNC 430 can optionally1) be equipped with an
Ethernet data interface. Via this interface, TNC 426/TNC 430 can be integrated into data
networks as client.
The TNC transfers data using the TCP/IP protocol (Transmission Control Protocol / Internet
Protocol) and with the aid of the NFS, version 2 (Network File System). Since TCP/IP and NFS
have been implemented in UNIX systems in the first place, you can usually connect the TNC in
the UNIX world without any additional software.
The PC world with Microsoft operating systems, however, also works with TCP/IP, but not with
NFS. For this reason, additional software is usually required for PC networks. HEIDENHAIN
recommends the following network software:
Operating system Network Software
WIN 2000
WIN XP
CIMCO NFS
available from HEIDENHAIN under ID 339737-xx
WIN Vista
WIN 7
In principle, other NFS servers can be used as well.
However, due to the great variety of software providers, HEIDENHAIN is not a in position to
provide technical support in adapting other NFS servers.
1)
Control models that can be operated with the Ethernet card: see chapter 2.
The network settings of the TNC are described in the Technical Manual and in
chapter 7 (Ethernet) of this Service Manual.

Attention
This modification applies for hardware handshake with TNC 145 to TNC 155. In these
control models, the RTS pin is not connected but tied high internally.
The following modification is required for hardware handshake:
Cut the line on both sides between DRS and DTR and short-circuit DSR with DTR
(at the PC: pin 6 with pin 20).
Without this modification, data transfer using hardware handshake is not only stopped but
aborted immediately (like "power off).
Do not use this configuration for TNC 335 with new hardware.

6 – 40 HEIDENHAIN Service Manual for Data Interfaces
Program end and program start
The control characters for "program end" and "program start" are defined in MP 71 (5010.0).
MP 71 (5010.0)LSB: Bit 0 - 7 = character for program end
MSB: Bit 8 - 15 = character for program start
In the example, the standard values "ETX" and "STX" are used, i.e. MP 71 = 515.
For serial data transfer only the character for program end is transmitted (in our example
"MP 71 = 3" would be sufficient for "ETX").
Both characters - program start and program end - are only sent with blockwise transfer.
(In our example "MP 17 = 515" would be required for "STX" and for "ETX".)
To select the characters for program start and program end via MP 71, the RS-232-C interface
must be set to "EXT" mode.
In the "FE" and "ME" modes the control characters "ETX" and "STX" are automatically set,
i.e. MP 71 must be 515.
In old control models (TNC 150; TNC 151 A/P; TNC 155 A/P) the machine parameter MP 71
is always active.
Machine parameters of TNC 145 C and TNC 150
MP 70:
Decimal point or comma ON = decimal point
OFF = decimal comma
If numerical values in programs are to be output with decimal points, the parameter MP 70 must
be programmed ON; if output with decimal comma is required, it must be programmed OFF.
MP 71:
Character for end of program 1 - 126
MP 76:
By means of the parameter 71 (TNC 159) or 76 (TNC 145 C) an additional ASCII character for
"program end" can be selected for remote programming. The input depends on the significance
of the character and is derived from the pattern on the punched tape (without parity bit).
MP 92:
Decimal point or comma 0 = decimal comma
1 = decimal point
If numerical values in programs are to be output with decimal points, the parameter MP 70 must
be programmed ON; if output with decimal comma is required, it must be programmed OFF.
Operating mode of the data interface
The operating mode of the data interface is defined in the machine parameter MP 223 (5030).
MP 223 (5030) 0 = blockwise transfer inactive
1 = blockwise transfer active
April 2010 6 – 41
Machine parameters for blockwise transfer
With Blockwise Transfer in the "Program Run" operating mode, machine programs - in general
created on a remote computer-aided workstation - of any desired length can be downloaded and
machined via the serial interface.
Blocks already machined are deleted from the memory and the next program blocks requested
from the external memory.
With BLOCKWISE TRANSFER the data flow is not stopped by RTS or DC3, but only by the
control characters ACK (acknowledge = positive) and NAK (not acknowledge = negative).
Each transferred block is checked by means of a BCC (block check character), i.e. the received
data are checked for longitudinal parity. If both values are the same, positive acknowledgment
is transmitted; if they are not identical, negative acknowledgment is transmitted.
This block is repeated up to three times. If the result is negative in each case, data transfer is
aborted and an error message generated.
For MP 218 (5010.1) and MP 219 (5010.2)
H = HEIDENHAIN conversational program
D = ISO program

Machine parameter calculation
Examples: MP 218 (5010.1) - MP 221 (5010.4) and MP 224 (5010.5)
MP 218 (5010.1) = 17736
The LSB must correspond to the transfer program.
("Change identifier" in FDE program)
X (88) - User parameter (general) ME mode
H (72) - Programs in HEIDENHAIN plain language
D (68) - ISO programs
P (80) - PLC programs
M (77) - Machine parameters
S (83) - Non-linear compensation table
The MSB must correspond to the transfer program.
("E" is prescribed in the FDE/TNC program.)
MP 219 (5010.2) = 16712
The LSB can be selected as in the above example; however, it must be the same for both
machine parameter and identifier.
The MSB is "A" as in the FDE/TNC program.
MP 220 (5010.3) = 279
SOH and ETB are fixed for the FDE/TNC program. Otherwise a substitute character can be
selected which must match the data transfer software.
MP 221 (5010.4) = 5382
ACK/NAK is defined for the FDE/TNC program; otherwise a matching substitute character can
be selected in the data transfer software.
April 2010 6 – 43
MP 224 (5010.5) = 4
Note
Prescribed for the FDE/TNC program; otherwise selectable as above.
For our example the following values must be entered in the machine parameter list:
MP 71 (5010.0) = 515 (STX, ETX)
MP 218 (5010.1) = 17736 (E, H)
MP 219 (5010.2) = 16712 (A, H)
MP 220 (5010.3) = 279 (SOH, ETB)
MP 221 (5010.4) = 5382 (NAK, ACK)
MP 222 (5020) = 168 (7 data bits, 1 stop bit, even parity, xon/xoff)
MP 223 (5030) = 1 (blockwise transfer active)
MP 224 (5010.5) = 4 (EOT)
Printer adaptation
General information on graphic output
Your printer manual is absolutely required!
Proceeding:
Via the DIP switches the printer must be configured such that it matches the configuration of
the control.
Control settings:
1. At the control, the RS-232-C interface must be set to EXT. (The interface can be selected
with the MOD key; pressing ENT changes the setting.)
2. The baud rate must also be selected via MOD and a value entered.
(Observe the settings of the DIP switches at the printer.)
3. Data format: 8 data bits, 1 stop bit, even parity, software handshaking. The data format is set
in MP 222 (MP 5020): 169.
4. The EXT control character for end of program is set in the machine parameter
MP 71 (MP 5010.0): 3.
5. Blockwise transfer must be deactivated in MP 223 (MP 5030): 0.
6. Enter MP 226 (MP 5110.0) to MP 233 (MP 5120.3).
Machine parameter calculation is explained on the following pages.
The printer manual is required to define the escape sequences.
The values determined must be entered in the machine parameter list.
6 – 44 HEIDENHAIN Service Manual for Data Interfaces
Machine parameter calculation for graphic output
In the graphics mode the display of the TNC 155/355 consists of 512 x 490 pixels. For graphic
data output, the data is output line by line in 8-bit format via the serial interface. A line consists
of 8 pixels and 512 bytes.
The parameters are subdivided into two blocks:
The first block (MP 226 (5110.0) to MP 229 (5110.3)) is sent once before each block.
It serves to initialize the printer and to set the general parameters for graphic output,
e.g. line spacing, carriage return, line feed and possibly form feed to reach the beginning of
the print paper.
The line feed must be specified such that the graphic lines are printed without blanks in
between. For this reason, the line spacing should be 72/216 inches.
The second parameter block (MP 230 (5120.0) to MP 233 (5120.3)) is output before each graphic
line to perform carriage return and line feed at the printer and to set it to the graphics mode.
The control outputs 512 data bytes per line, i.e. 512 bytes must be displayed as graphics on
paper before the printer automatically switches from the graphics mode to ASCII mode.
The commands for the printer are described in escape sequences which may vary from
printer to printer.
The EPSON command set for printers is a quasi-standard supported by most printer
manufacturers. Therefore, this manual refers to these EPSON ESCAPE SEQUENCES.
April 2010 6 – 45
The following escape sequences and ASCII characters must be transferred to the printer for
initialization:
The machine parameters MP 226 (5110.0) to MP 233 (5120.3) are present as 16-bit values and
are output in decimal format. The input value may be between 0 and 65535. These machine
parameters are subdivided into bytes.
The most significant byte from MP 226 (5110.0) and MP 230 (5120.0) defines the number of
bytes the control outputs via RS-232-C.
The entry values 0 to 7 are advisable, as up to 7 bytes can be transferred. The next bytes are
output individually in ascending order.
Example:
The escape sequences stated below are not generally valid; they must be defined individually
for each printer (with the help of the printer manual).

A Remote Procedure Call that is not answered by the NFS server is repeated
after expiration of the time defined here. 0 = 700 (standard)
HM: 1=YES / 0=NO: With a hard mount, the Remote Procedure Call is repeated
until an answer is received from the NFS server. This has the
advantage that after a server crash you can continue normal operation as soon
as the server is up again. Use a soft mount (0) only, if the NFS server is not
always available.

8.2 Ethernet Error Messages
ErrInternetor messages or warnings that are generated when a device is mounted, are stored in
plain language in an ERROR file.
When the control is switched off and on, the contents of this file is deleted.
The entries in this file can be viewed by entering the code number "NET123" and pressing the
soft key "SHOW ERROR".
Structure of an Error Message
A message starts with the program part that detected the error; this element is terminated by a
colon. Then the name of the device to be mounted can follow in <> angle brackets. The software
differentiates between errors (E) and warnings (W). In the event of an error the network cannot
be activated and the device cannot be mounted. When a warning is generated, the network
could be activated or the device mounted, however, inappropriate entry values were corrected.
Errors reported by the link layer:
LL: (W) CONNECTION "error string" UNKNOWN USING DEFAULT 10BASE2
An unknown name was entered for the connection.
10BASE2 (Thin Ethernet) is used.
LL: (E) PROTOCOL "error string" UNKNOWN
An unknown name was entered for the protocol.
Errors detected by the network layer:
IP4: (E) INTERFACE NOT PRESENT
The Ethernet card could not be found.
IP4: (E) INTERNET ADDRESS NOT VALID
The control was assigned an invalid Internet address; e.g. a class D or E address,
a loop-back address or a broadcast address.
IP4: (E) SUBNETMASK NOT VALID
The specified subnet mask does not match the Internet address, or only 1 bit
was provided for the subnet ID or the host ID.
IP4: (E) SUBNETMASK OR HOST ID NOT VALID
Input of Internet address or subnet mask faulty, or all bits of the host ID are 0 or 1.
IP4: (E) SUBNET MASK OR SUBNET ID NOT VALID
All bits of the SUBNET ID are 0 or 1.
IP4: (E) DEFAULTROUTERADRESS NOT VALID
For the default router an invalid Internet address was entered; e.g. a class D or E address,
a loop-back address or a broadcast address.
IP4: (E) CANNOT USE DEFAULT ROUTER
The net ID and the subnet ID of the default router are not identical to those of the control.
IP4: (E) I AM NOT A ROUTER
The Internet address of the default router is identical to that of the control.
Errors detected by the mount system call:
MOUNT: <Device name> (E) DEVICENAME NOT VALID
The device name is either too long or it contains illegal characters.
MOUNT: <Device name> (E) DEVICENAME ALREADY ASSIGNED
A device with the same name already exists
MOUNT: <Device name> (E) DEVICETABLE OVERFLOW
