Configuring the fieldbus
7.5 Communication via EtherNet/IP
Inverter with CU230P-2 Control Units
138 Operating Instructions, 11/2013, FW V4.6.6, A5E02430659B AG
Commissioning the inverter in an EtherNet/IP network
To commission the inverter, using STARTER you must access the inverter via the USB
interface. To do this, connect the computer to the inverter via the USB interface. See also
Basic commissioning with STARTER (Page 85).
What do you need for communication via Ethernet/IP?
Check the communication settings using the following questions. If you answer "Yes" to the
questions, you have correctly set the communication settings and can control the inverter via
the fieldbus.
● Is the inverter correctly connected to the EtherNet/IP?
● Is the EDS file (Page 137) installed in your control system?
● Have the bus interface and IP address been correctly set?
● Have the signals that the inverter and the control system exchange been correctly
interconnected?
Communication settings for Ethernet/IP
General communication settings
In order to be able to communicate with a higher-level control system via EtherNet/IP, you
must set parameter p2030 = 10.
Further, you must set the following data:
IP address
currently valid value in r8931
Subnet mask
currently valid value in r8933
Default gateway
p8922
currently valid value in r8932
Name of station
currently valid value in r8930
These parameters apply if p2030 = 10 is set, for EtherNet/IP, even if the parameter name
indicates PROFINET.
Modified addresses only become effective if you switch-off the inverter and switch it on
again; this includes any external 24 V supply that is being used.
Additional settings for communication via EtherNet/IP
Setting the communication profile
The inverter has two communication profiles
● p8980 = 0: SINAMICS profile (factory setting)
A drive profile defined by Siemens for EtherNet/IP based on PROFIdrive
● p8980 = 1: ODVA AC/DC drive profile
A drive profile defined by the ODVA organization
