EtherNet/IP Overview

1.1.1

Industrial Ethernet

Industrial Ethernet communication networks continue to gain global importance in
automation solutions. Industrial Ethernet connectivity down to device level
components (i.e. drives, I/O, etc.) is an end user requirement that demands
openness and flexibility. To capitalize on the flexibility to connect to different
Industrial Ethernet protocols the SINAMICS S120 drives can seamlessly be applied
in PROFINET and EtherNet/IP networks.
1.1.2

SINAMICS S120 Connectivity to EtherNet/IP

Since Firmware version 5.1SP1 both the CU310-2 PN and Cu320-2 PN can be
commissioned for EIP via on board Ethernet ports. The CBE20 is no longer
necessary for EIP communication and the onboard X150 ports are utilized for EIP
communication.
The network IP address of the S120 CU (Control Unit) is set through the STARTER
or STARTDRIVE software. With STARTER software installed on your computer
you can connect to the SINAMICS drive through the built in X150 ports on
CU310-2 or CU320-2 and set IP address.
The SINAMICS S120 multi-axis drive system can contain up to six vector or servo
axis controlled by a single CU320-2 control unit. This allows one IP address for the
CU320-2 to control multiple drive objects thus cutting down on the number of IP
addresses and Ethernet connections required for drive systems. For the CU310-2
it is a single drive axis but can have additional control and status for the Control
Unit if needed.
The SINAMICS drives operate on unicast telegrams thus further reducing network
traffic. SINAMICS S120 drives have been certified by ODVA for EtherNet/IP
conformance testing and participated in the EtherNet/IP PlugFest. Siemens is a
member of ODVA with Vendor ID # 1251.
