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 and PROFINET 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)

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.
