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

different 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

digital 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

different fieldbuses 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

Master 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. Hex-

adecimal numbers are always marked with the prefix 0x.
