Deutschmann Automation GmbH & Co. KG Generalintroduction
1 General introduction
In the past the integration of a fieldbus connection required an enormous effort from the progress
engineers. On account of the large variety of communication systems it is not enough to compile
the right combination of communication hardware; due to their standards and fundamentals dif-
ferent busses also require the corresponding skills of the engineers.
This does not apply in case of the UNIGATE® IC by Deutschmann Automation any more. All dig-
ital functions, software, stack and driver as well as optocoupler are integrated on a UNIGATE®
IC in correspondence with the standard. In addition to the reduction of the required size, also dif-
ferent fieldbusses can easily be integrated.
Through the flexible firmware of UNIGATE® IC no software-changes are required on the
side of the customer!
Since 1997 Deutschmann Automation has experience in the field of fieldbus gateways; this
enormous experience results in the UNIGATE® IC as a consistent sequel of this successful
product line.
Terminology
In the entire document and in all parts of the software that is to be used, the terms Input and Out-
put are used. Input and Output are ambiguous, always depending on the viewpoint. We see the
fieldbus as central interface and as integral component of your device; therefore in all places it is
always referred to data from the viewpoint of the Slave, that is Input data, as data from the Mas-
ter to the Slave - regardless of the used bus.
Representation of numbers
Numbers in decimal format are always represented without prefix and without suffix as well.
Hexadecimal numbers are always marked with the prefix 0x.

2 The UNIGATE® IC
2.1 Technical introduction
The UNIGATE® IC by Deutschmann Automation contains all components that are required for
the communication in a fieldbus in one single module. Therefore a developer does not have to
take care for that detail any more, only a hardware redesign is necessary in order to integrate the
UNIGATE® IC and the required plug connectors.
2.2 Availability
The module is available as Ethernet/IP. Further fieldbusses are either planned or being worked
on. They will only differ in the connections of the busses. The meaning of the general pins 1 - 9
as well as 24 and 26 - 32 will remain unchanged also for further fieldbus implementations.
You can find an up-to-date list for all UNIGATE ICs under:
http://www.deutschmann.de.
2.3 Firmware
UNIGATE® IC is programmed via scripts. On principle any script, that has been developed for a
UNIGATE® IC, can also be operated on the UNIGATE® IC.
2.4 The serial standard interface
Intelligent devices, that already feature a micro controller or a microprocessor, are generally sup-
plied with a serial asynchronous interface with a TTL-level. It is directly connected with the TTL-
interface of the UNIGATE® IC. For more information on this serial interface see chapter 4 on
page 21.
2.5 The synchronous interface
In addition to the standard interface there is also the possibility of the synchronous input and out-
put. That way for instance digital IOs can be connected through shift register components or also
analog IOs can be connected through a DA-converter with serial in-/output. For synchronous IOs
256 signals at the most can be used (256 bit). Wiring examples can be found in chapter 3.5 and
for software examples see chapter 5.1. It is also possible to build, for instance digital or analo-
gous I/O-modules, with the customer’s device not being equipped with an own controller. The
fieldbus IC is also operable autonomously without that controller.
2.6 The Debug-interface
The UNIGATE® IC features a Debug-interface, which allows to process a script step by step and
also to monitor or manipulate data. This is indispensable for the development of a script. Usually
a script is developed with the software Protocol Developer. For more details take a look at the
instruction manual Protocol Developer.
All interfaces can independently be used at the same time.

3 Hardware design
This chapter gives basic advise, that is required in order to load UNIGATE® IC into your own
hardware designs. In the following all ports of UNIGATE® IC are described in detail.
3.1 Ports
UNIGATE® IC features 32 pins in its layout as a DIL 32 component. Pin 10 -12 and 21 - 23 as
well are not wired due to the electrical isolation. The exact mechanical dimensions can be taken
from chapter 15 on page 34.
In the layout boreholes for ALL 32 pins have to be planned.

3.2.1 -Boot enable
The IC is started in the firmware update mode with the level GND during the power up process.
See also chapter 14 on page 33.
3.2.2 Load out
Strobe signal for the synchronous serial interface. With the positive edge at this output data is
taken from the connected shift registers to the physical outputs.
3.2.3 Data out
On this line data is output on the synchronous serial interface. The most significant bit of the data
is output first.
3.2.4 Data In
Data is read in on the synchronous serial interface via this signal. The most significant bit of the
data is expected first.
3.2.5 Load In
This pin is the strobe signal for the input data of the synchronous serial interface.
3.2.6 Clock
This signal is the clock line for the synchronous serial interface. That signal is equally valid for
data input and data output.
3.2.7 -Reset In
•A reset generator (Max 809) is on board; with it in the normal case the reset input is not
required. In this case the reset input has to be connected with VCC, in order to avoid interfe-
rences (see chapter 3.6).
•If the the customer’s application has to initiate a reset of the UNIGATE® IC, then the reset input
can also be connected with a reset output of the customer’s application instead of connecting it
with VCC. Here all specifications of the reset signal, mentioned in chapter 3.2 have to be kept.
The reset-impulse is supposed to last at least 10 ms.
3.2.8 LED-EI
A green LED can be connected to this line (see chapter 3.6). It is glowing in the state of “Ethernet
ok, data exchange active“ and in the state “Waiting for link connection“ it is flashing.
3.2.9 -Config Mode
If the pin has the level GND, then the IC starts in the configuration mode.
3.2.10 DbgTX, DbgRx
They are transmission line and receive line as well of the IC’s Debug-interface. For the function
description of the Debug-interface see chapter 6 on page 23.

Hardware design Deutschmann Automation GmbH & Co. KG
14 Instruction manual UNIGATE®IC - Ethernet/IP V. 1.8 12.10.10
3.2.11 TE
The transmit enable signal allows the connection of RS485 drivers to the IC’s serial interface.
The signal is set to High whenever the IC sends via the line TX.
3.2.12 TX, RX
Transmission and receive line of the serial interface. This interface is programmable in accor-
dance with the description in chapter 4 on page 21.
3.3 Software
The software executes script-commands, which in turn control the IC’s hardware and they pro-
cess their complete protocol by software. The script itself can be generated by the company
Deutschmann Automation or with the software Protocol Developer by yourself. For a detailed
description of the script.commands of the Protocol Developer see the instruction manual Proto-
col Developer and the online documentation concerning script-commands.
3.4 Basic line of proceeding
In theory it is enough to replace the RS232-driver that is included in your application by the UNI-
GATE® IC.
Your device, which on the whole is supposed to be assembled as shown above, will now be mod-
ified in a way that the Ethernet/IP is available at the 9-pol. socket. However, a hardware redesign
is necessary in order to keep the assignment in standard form.

12.10.10 Instruction manual UNIGATE®IC - Ethernet/IP V. 1.8 15
Deutschmann Automation GmbH & Co. KG Hardwaredesign
After the RS232-driver has been replaced by the UNIGATE® IC, Ethernet/IP is available at an
RJ45-socket.
3.5 Connection examples
Here you will find some advise that offers help for a re-design. In the following several versions
are listed, that should make it easier for you to decide.
Version 1: Use as a pure link module for the bus
The UNIGATE® IC independently processes the communication with the customer’s device via
the TTL-interface.

Hardware design Deutschmann Automation GmbH & Co. KG
16 Instruction manual UNIGATE®IC - Ethernet/IP V. 1.8 12.10.10
Version 2: Use of UNIGATE® IC for digital or analog I/O-modules
Here only the synchronous serial interface is used, the asynchronous serial interface is basically
of no account. If you want to program the script in your completed application, then the use of a
connector for the asynchronous interface is recommended. With it you can carry out the ISP-pro-
gramming.
For this operating mode no additional controller is required on your application!

12.10.10 Instruction manual UNIGATE®IC - Ethernet/IP V. 1.8 17
Deutschmann Automation GmbH & Co. KG Hardwaredesign
The following circuit diagram is an example for how shift register components can be connected
to the IC.
Version 3: Example for digital I/Os
The serial synchronous and the asynchronous interface as well can be operated by UNIGATE®
IC at the same time. Here the possibility results that an existing application can be extended by
additional digital or analog I/Os.
In chapter 5.2 you find an example for a script, that operates these I/Os.
Valid for all versions: A planed plug connection of the serial interface in the application offers the
possibility of an update of the firmware or the software via an external connection.

3.7 Handling (mounting the UNIGATE IC on the carrier board)
Depending on the application and the expected shock- and vibration-conditions you can choose
from the following possibilities for the UNIGATE IC’s installation on the carrier board:
•Mounting on a socket in the carrier board. If necessary solder the UNIGATE IC to 2 or 4 pins in
the socket. Normally the IC can easily be pulled out after the soldering points have been re-
moved.

•Make arrangements for two holes next to the socket in the layout. After the UNIGATE IC was
plugged in the socket pull an isolated wire over the IC and solder it on the carrier board at the
specified holes.
•Fasten the UNIGATE IC With a wire or a tie wrap on the socket.
•Manual soldering directly on the carrier board.
•Automatic soldering directly on the carrier board, whereas „selective“ soldering is essential (no
wave soldering)
The advantage of the socketed variant is the easy download of Script- and Firmware-updates, if
the carrier board is not designed for it. Besides, that way the Fieldbus can be changed easily by
changing the UNIGATE IC if the corresponding plug connectors are provided on the carrier
board. Another advantage is, that - normally - only a reflow soldering of the carrier board is ne-
cessary.
The advantage of the soldered variant is, that the installation height is lower and a higher shock-
and vibration-safety is provided.
