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.

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.

Windows 2000, Windows XP, Windows Vista and Windows 7 are registered trademarks of the Microsoft Corporation.

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

Udmin = 2 V and Udmax = 5 V are output; the control detects the differential voltages

between

Udmin = 0.2 V and Udmax = 6 V as logically defined levels.

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

HEIDENHAIN Service Manual for Data Interfaces

2.3.1 Hardware

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.

2.3.2 Signal structure

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.

2.3.3 Connecting the TNC to data networks

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	CIMCO NFS
WIN XP	available from HEIDENHAIN under ID 339737-xx
WIN Vista
WIN 7
Note

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.
