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.

What do you have to set for communication via PROFINET?
Configuring PROFINET communication
Proceed as follows to configure the PROFINET communication between the IO Controller and
the inverter as IO Device:
1. Configure the IO Controller and the IO Device with an engineering system, e.g. with HW-
Config.
If required, install the GSDML file of the inverter in the engineering system.
2. Load the configuration data into the IO Controller.
Device name
In addition to the MAC address and IP address, PROFINET also uses the device name to
identify PROFINET devices. The device name must be unique across the PROFINET network.
To assign the device name, you need an engineering software, e.g. HW-Config or STARTER.
The inverter saves the device name on the inserted memory card.
IP address
In addition to the device name, PROFINET also uses an IP address.
You have the following options to specify the IP address of the inverter:
● You specify the IP address via an engineering software, e.g. via HW-Config or STARTER.
● The IO Controller assigns an IP address to the inverter.
Telegram
Set the same telegram in the inverter as in the IO Controller. Interconnect the telegrams in the
control program of the IO Controller with the signals of your choosing.
