PROFIBUS DP Interface
The function of the PROFIBUS DP interface is to provide a PROFIBUS DP-based link
between inverters of the SINAMICS G120 product range and higher-level automation
systems e.g. SIMATIC S7.
Configuration with SIMATIC S7
The layout of the PROFIBUS DP interface and the DIP switches for setting the PROFIBUS
DP address are shown in the Commissioning section.
4.3.1

Setting the PROFIBUS DP address via DIP Switches

Setting the PROFIBUS DP address
Prior to using the PROFIBUS DP interface, the address of the node (inverter) must be set.
There are two methods for setting the PROFIBUS DP address:
● Using the seven PROFIBUS DP address DIP switches on the Control Unit
● Using parameter "P0918".
The PROFIBUS DP address can be set between 1 and 125.
Note
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.
Caution
The power supply must be switched off before the DIP switch settings are changed. DIP
switch setting changes do not take effect until the Control Unit has been powered-up again.
The restart must be initiated by switching the power off and on again irrespective of whether
the Control Unit is supplied with the inverter line supply or its own, separate 24 V connection.
