Mode of operation of the system

6.1

General explanation

Communication can be split into seven layers, Layer 1 to Layer 7, in accordance with the ISO/
OSI model.
The Deutschmann Automation Gateways convert Layers 1 and 2 of the customized bus system
(RS485 / RS232 / RS422) to the corresponding Fieldbus system. Layers 3 to 6 are blank, and
Layer 7 is converted in accordance with chapter 27.3.
6.2

Interfaces

The Gateway features a CANopen interface and a switch with 2 EtherNet/IP ports as well as the
serial interfaces RS232-, RS422- and RS485 and Debug interface.
6.3

Data exchange

All data is transferred by the Gateway in dependence of the downloaded Script.
6.4

Possible data lengths

The table below shows the maximum transferable data:

Startup phase

The Gateway is parameterized and configured by the Master during the startup phase. Only after
a correct termination of the startup phase the data exchage with external devices will take place.
