The UNIGATE® IC
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:

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 20.
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 21. 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.
