4.8 Connecting the inverter to the fieldbus
General information about PROFINET
You can find general information about PROFINET in the Internet:
● General information about PROFINET: Industrial Communication
(http://www.automation.siemens.com/mcms/automation/en/industrial-
communications/profinet/Pages/Default.aspx).
● Configuring the functions: PROFINET system description
(http://support.automation.siemens.com/WW/view/en/19292127).
This manual describes the control of the inverter using primary control. Accessing the
inverter as an Ethernet node is described in the "Fieldbus" function manual.
4.8.2.1

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 control match?
Is the same telegram set in the in-
verter as in the higher-level control?
Are the signals that the inverter and
the control exchange via PROFINET
correctly interconnected?
4.8.2.2

Integrating inverters 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 sockets X150-P1 and X150-P2.
The maximum permitted cable length from the previous station and to the next one is 100
m.
2. Externally supply the inverter with 24 VDC through terminals 31 and 32.
The external 24 V supply is only required if communications with the control should also
run when the line voltage is switched off.
You have connected the inverter to the control using PROFINET.
