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 25.3.
6.2

Interfaces

The Gateway features a CANopen and fieldbus interface as well as the serial interfaces RS232-,
RS422- and RS485.
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:
Input data (Consumed)
DeviceNet
Output data (Produced)
C4Map
In- and
Output data
6.5

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.
