CX C4Map - PROFIBUS V. 1.0 13
Deutschmann Automation GmbH & Co. KG Mode of operation of the system
6 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 24.3.
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

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.
