6.3 Communication via PROFINET
Further information on PROFINET can be found on the Internet using the following links:
– General information about PROFINET can be found at Industrial Communication
– The configuration of the functions is described in the PROFINET system description
This manual describes the control of the inverter using primary control. How to access the
inverter as an Ethernet station is described in the Fieldbus function manual (Page 387) in the
section "The inverter as an Ethernet station".
6.3.1

What do you need for communication via PROFINET?

Check the communication settings using the following table. If you answer "Yes" to the
questions, you have correctly set the communication settings and can control the inverter via
the fieldbus.
Questions
Is the inverter correctly connected to
the bus network?
Do the IP address and device name in
the inverter and controller match?
Is the same telegram set in the inverter
as in the higher-level controller?
Are the signals that the inverter and
the controller exchange via PROFINET
correctly interconnected?
6.3.2

Integrating converters into PROFINET

Procedure
To connect the inverter to a control via PROFINET, proceed as follows:
1. Integrate the inverter in the bus system (e.g. ring topology) of the control using
PROFINET cables and the two PROFINET jacks X03 and X04.
The position of the jacks and the pin assignment can be found in Section Overview of the
interfaces (Page 34).
The maximum permitted cable length from the previous station and to the subsequent
one is 100 m.
2. Externally supply the inverter with 24 V DC through X01.
The external 24 V supply is only required if communications with the control should also
run when the mains voltage is switched off.
You have connected the inverter to the control using PROFINET.
