Deutschmann Automation GmbH & Co. KG General introduction
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 DeviceNet. 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. An up-
to-date list for all UNIGATE ICs can be found at:
http://www.deutschmann.de
2.3 Firmware
UNIGATE® IC is programmed via scripts. On principle any script, that has been developed for a
UNIGATE® SC, 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 17.
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
software examples can be found in chapter 5.1 on page 18. It is also possible to build, for
instance digital or analogous 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 taken
from chapter 11 on page 27.
In the layout boreholes for ALL 32 pins have to be planned.
3.2 Pinout
* The supply voltage is 5 V +/- 5 %, max. 75 mA DC.
The DeviceNet signals are galvanically isolated. The insulation voltage is 1000 Vrms.
