What do you have to set for communication via PROFIBUS?

Configuring PROFIBUS communication
Proceed as follows to configure the communication between the PROFIBUS master and the
inverter as PROFIBUS slave:
1. Configure the PROFIBUS master and the PROFIBUS slave with an engineering system,
e.g. with HW-Config.
If required, install the GSD file of the inverter in the engineering system.
2. Load the configuration data into the PROFIBUS master.
Setting the address
Set the address of the PROFIBUS slave.
Setting the telegram
Set the telegram in the inverter as in the PROFIBUS master. Interconnect the telegrams in the
control program of the PROFIBUS master with the signals of your choosing.
Application examples
You can find application examples for PROFIBUS communication on the Internet:

Communication with the controller even when the supply voltage on the Power Module is
switched off
You must supply the Control Unit with 24 V DC at terminals 31 and 32 if you wish to maintain
communication with the control system when the line voltage is switched off.
In the case of brief interruptions of the 24 V power supply, the inverter may signal a fault without
communications with the control system being interrupted.
