2Introduction
This document explains the initial commissioning of the PN/EtherNetIP
Coupler. The latest version of the documentation can be found at
www.helmholz.de or scan the QR code directly.
3Function of the PN/EtherNetIP Coupler
With the PN/EtherNetIP Coupler, a simple and uncomplicated connection of a PROFINET machine to an
EtherNet/IP machine is possible. The PN/EtherNetIP Coupler allows data transmission between a
PROFINET controller and an EtherNetIP scanner.
Received input data on one of the network
sides are made available as output data on
the other network side of the PLC. The I/O
data exchange takes place live and as quickly
as possible without further handling
modules.
The maximum size of the transferable I/O
data is 1024 bytes. Up to 3 input and 3
output assemblies can be configured on the
EtherNet/IP network side. Up to 300 slots
are available for I/O modules.
The integration into the PLC engineering
tool is made possible by a GSDML file, an
extra configuration software is not necessary. The configuration of the I/O data to be exchanged is
carried out in the Siemens engineering tool. An EDS file matching the configuration can then be
downloaded from the website by the PN/EtherNetIP Coupler and used to configure the EtherNet/IP PLC.
Ethernet/IP Input assemblies contain output data of the PROFINET PLC, EtherNet/IP Output
assemblies provide input data to the PROFINET PLC.
The PN/EtherNetIP Coupler provides beside the PROFINET / EtherNetIP communication also a MQTT
Publisher on both network sides. This enables the values exchanged via the gateway to be distributed to
visualization or production data acquisition systems via MQTT.

4Connection
The left RJ45 sockets "X1 P1" and "X1 P2" are used to connect the PROFINET network, the right RJ45
sockets "X2 P1" and "X2 P2" are used to connect the EtherNet/IP network.
The PN/EtherNetIP coupler must be connected to the wide range input DC 18 ... 30 V via the supplied
connector plug, the PN/EtherNetIP Coupler must be supplied with DC 24 V. The power supply is
designed redundantly, at least one supply path PS 1 or PS 2 must be connected.
The housing of the PN/EtherNetIP coupler is not grounded. Please connect the functional grounding
connection (FG named FE on front) of the PN/EtherNet/IP coupler correctly with the reference
potential.
5Install GSDML file
Please download the GSDML file ("GSDML-V2.35-Helmholz-PN-EthernetIP-coupler-
_____.xml") from www.helmholz.de or scan the QR code. Install the GSDML file in the
TIA Portal under the menu "Tools" / "Manage general station description file (GSD)".
The PN/EtherNetIP Coupler is listed in the hardware catalog
under "Other field devices / PROFINET IO / Gateway / Helmholz
GmbH & Co. KG".

6Configuration in TIA Portal
The data exchange between the PROFINET and the EtherNet/IP side of the PN/EtherNetIP coupler is
defined exclusively via the Simatic Engineering Tool. New EtherNet/IP assemblies can be created in the
slots of the PROFINET configuration and I/O data of the PROFINET PLC can be assigned to these
assemblies. Up to 300 slots are available for this purpose.
The first module to be inserted is always a module of type "New Input
assembly" or "New Output assembly". Then either input or output
modules with the desired data size can be attached.
The assembly number can be set as parameter for the modules for the
start of a new assembly. The input and output modules have no
parameters.
The PROFINET data are now assigned in the order in which they were
specified in the slots.
After a module "New Input assembly" only input modules may be arranged and after a module "New
Output assembly" only output modules may be arranged. If the module types are mixed, the
PN/EtherNetIP coupler generates a configuration diagnosis.
Data exchange between the EtherNet/IP assemblies and the PROFINET EA data takes place in the
PN/EtherNetIP Coupler as quickly as possible when new data is received.

6.1 Parameters of the PN/EtherNetIP coupler
The PN/EtherNetIP Coupler can be parameterized completely via the PROFINET Hardware Configurator
(e.g. TIA Portal). However, some parameters can optionally be set via the web page, e.g. the IP address of
the device on the EtherNet/IP network side or the DHCP host name.
EtherNet/IP IP-address-Mode: Defines the IP address for the EtherNet/IP network. Possible options are
"DHCP", "Static IP" or "IP address from web page".
Static IP address:If the address mode is set to "Static IP", the static IP address can be specified here.
Static IP subnet mask:If the address mode is set to "Static IP", the subnet mask can be specified here.
Static IP gateway: If the address mode is set to "Static IP", the gateway can be specified here
Hostname mode:"From PROFINET configuration" or "Use from web page"
EtherNet/IP product name / DHCP hostname: Name of the device
EtherNet/IP product code: Number of the device in the EtherNet/IP network. The number is used in the
EDS file. If more than one PN/EtherNetIP coupler is used in an EtherNet/IP network, this code must be
different for each device!
Data alignment in assemblies: If the EtherNet/IP PLC cannot address data by byte alignment it is
possible to force the Coupler to align the data to word or double-word addresses.
Swap Byte Order: For 2-byte and 4-byte values, the PN/PN coupler can swap the byte order if required.
The standard for values via PROFONET is "Big Endian". The "Swap Byte Order" option can be used if the
data is transferred in Little Endian in the Ethernet/IP assemblies due to the PLC used.
Webpage:On which network interfaces should the website be displayed
MQTT Publisher Option: On which network interfaces the MQTT Publisher should be activated.

6.2 Assign a name to the PN/EtherNetIP coupler
When the configuration of the PN/EtherNetIP coupler is completed in the hardware configurator of the
engineering tool, it can be imported into the PLC.
To enable the PN/EtherNetIP Coupler to be found by the PROFINET controller, the PROFINET device
name must be assigned to the PN/EtherNetIP Coupler. To do this, use the "Assign device name" function,
which you can access with the right mouse button or in the Online menu if the PN/EtherNetIP Coupler is
selected.
Use the "Update list" button to search the network for PROFINET stations. With "Assign name" the
PROFINET device name can be assigned to the device.
The unique identification of the PN/EtherNetIP coupler is guaranteed here by the MAC address of the
device. The PROFINET MAC address can be read on the front of the PN/EtherNetIP Coupler on the left-
hand side at X1 ("MAC 1").
If the PN/EtherNetIP coupler has received the correct PROFINET name, it is recognized and configured by
the PLC. If the configuration is correct, the PROFINET "BF" LED should be off.
To set the PROFINET name, the Helmholz IPSet Tool can also be used, which can be
downloaded free of charge from the Helmholz website.
Scan the following QR code to download the IPSet Tool:

7Configuration in Rockwell Studio
7.1 Access the website and download the EDS file
As soon as the PN/EtherNetIP Coupler has been configured via the PROFINET PLC, the website of the
device can be accessed via the PROFINET network. If the IP address is also available on the EtherNet/IP
network side (Static-IP, DHCP successful), the website can also be accessed via the EtherNet/IP network.
At the first access to the device a password must be assigned for the user "admin".
In the submenu "EtherNetIP" the network settings can be made, if they are not predefined by the
PROFINET configuration, and the EDS file with the currently valid I/O configuration can be downloaded.
The currently valid configuration can be checked in the "Module config" menu.

QuickStart Guide PN/EtherNetIP Coupler | Version 3 | 13.08.2020 9
The currently valid configuration can be
checked in the "Module config" menu.
The current transferred data is also displayed
here.
7.2 Load EDS file and configure the PN/EtherNetIP coupler
Import the EDS file into the Studio 5000 with the
function "EDS Hardware Installation Tool" in the
menu "TOOLS".
The name of the file is defined by the parameter "EtherNet/IP product name / DHCP host name" in the
PROFINET configuration.
The number specified in the PROFINET configuration in the parameter "EtherNet/IP product code" is
used in the EDS file to distinguish several couplers in an Ethernet/IP network. Select any different
numbers and product names to differentiate the devices.

QuickStart Guide PN/EtherNetIP Coupler | Version 3 | 13.08.2020 10
The module may be added to the hardware configuration under its order number (700-160-3EN02).
The assembly definitions are also available
through the EDS import.
The assemblies are based on the data type
"SINT" and have a length that corresponds
to the data defined in the PROFINET
configuration.
The Rockwell Studio can manage assemblies of up to 500 bytes. If more data is to be exchanged
between the PROFINET PLC and the EthernetIP PLC, additional assemblies must be created.
