7.3 Communication via PROFIBUS
Connect the converter to PROFIBUS
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 position of the sockets and the pin assignment can be found in Section Connection
and cables (Page 63).
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 terminals 31 and 32.
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.
Configuring the communication using SIMATIC S7 control
● If the inverter is listed in the hardware library of HW-Conifg, you can configure the
communication in the SIMATIC control.
● If the inverter is not listed in the hardware library, you can either install the newest
STARTER version or install the GSD of the inverter through "Extras/GSD-Install file" in
HW-Config. See also GSD
When you have installed the GSD, configure the communication in the SIMATIC control.
Settings PROFIBUS DP address with DIP switches
Setting the PROFIBUS DP address
Prior to using the PROFIBUS DP interface, the address of the node (Inverter) must be set
using the seven PROFIBUS DP address DIP switches on the Control Unit.
The PROFIBUS DP address can be set between 1 and 126.
The address is taken from P0918 if all PROFIBUS DP address DIP switches are in the OFF
position, otherwise the DIP switch setting is valid.
