Security
The device is a network infrastructure component and therefore an important element in the
security consideration of a plant. When using the device, therefore, observe the relevant
recommendations to prevent unauthorized access to installations and systems. Further
information on this can be found in the device manual.
2Introduction
Please consider the safety instructions for the product, which can be
found in the PROFINET-Switch manual. You can download the manual
from the website www.helmholz.de in the download area of the product
or use the shown QR code.
This document is intended to explain the initial commissioning of the PROFINET
switch in a standard application case.
3Preparing the PROFINET switch
3.1 Connecting
The PROFINET switch must be supplied with 24 V
DC at the wide range input 18 - 30 VDC via the
L-coded M12 connector (X2).
The connection (FE) is for the functional earth.
Connect it properly to the reference potential.
The D-coded M12 sockets "P1 - P8" (X1) are used to
connect the network nodes (PROFINET or
Ethernet).
The inputs D1 and D2 do not yet have a function in
the current firmware version and will be available
for possible additional functions in a later firmware
version.

4Setup and use
4.1 Install GSDML file
You can download the GSDML file from the website www.helmholz.de in the download
area of the product or use the shown QR code.
Install the GSDML file in the TIA Portal menu “Options” / “Manage general station
description files (GSD)”.

4.2 Setup in the hardware-configuration
Following installation, the PROFINET switch can be found in the hardware catalog under “Other field
devices -> PROFINET IO -> Network Components -> Helmholz GmbH & Co. KG -> Helmholz PN-Switch”.
Add the “PROFINET-Switch, 8-port, IP67” device to the project and connect it with your PROFINET
network.
By calling up the device properties, you must assign the PROFINET switch a unique PROFINET name in
the project and check the IP address for plausibility.
The real device must later be assigned the same name as in the project.

4.3 Setting the port properties
Each port of the PROFINET switch can be individually configured.
“Activate this port for use”
The port can be switched off here. This option is recommended when
the port should not be used. Unauthorized trespass into the network is
prevented.
Transmission rate / duplex:
“Automatic”
The port synchronizes itself automatically with the communication
partner (auto-negotiation).
Transmission rate / duplex:
“TP 100 Mbps full duplex”
Fixed specification of the transmission rate. This option is
recommended when connecting PROFINET IO devices.
Monitor
Send a diagnosis by Link Down
Enable autonegotiation
Automatic recognition of the transmission speed and the cable type
(cross or patch cable)
End of detection of
accessible devices
The DCP telegrams for recording accessible devices are not forwarded
from this port. Subscribers behind this port are no longer displayed
under "Accessible subscribers" in the topology. Users behind this port
can no longer be reached by the CPU.
End of topology discovery
LLDP frames for topology discovery are not forwarded on this port.

4.4 Topology detection
The PROFINET-Switch supports the mechanisms for neighborhood detection (LLDP). With this function
it is possible to detect the topology of a PROFINET network, or to specify it for purposes of checking for
the correct structuring by the configuration.
If the topology was prescribed in the configuration, neighboring devices can also be assigned the
PROFINET name in the event of the replacement of a device. This makes the recognition and testing of
the network topology and the “device exchange in operation” of connected PROFINET participants
possible.

4.5 Media Redundancy Protocol (MRP)
The PROFINET-Switch supports the
optional media redundancy protocol (MRP)
as MRP client. MRP stands for “media
redundancy protocol”. MRP enables ring
wiring, which also makes operation of the
PROFINET network possible in the event of
the failure of a cable or of a participant.
There must be at least one MRP master
(e.g. the CPU) in an MRP ring. All other
participants of the ring are then MRP
clients.
In order to assign the PROFINET-Switch to
an MRP ring, the “MRP domain” must be
set at slot X1 for the option “Media
redundancy role” and the role set to
“Client”.
Important: If ring wiring is established without the MRP roles being configured for all devices involved, this can
result in functional disruptions of the PROFINET network!

4.6 Assign the PROFINET switch a name
When the configuration of the PROFINET switch has been completed in the hardware configurator of
the engineering tool, it can be loaded into the PLC.
In order that the PROFINET switch can be found by the PROFINET controller, the PROFINET device
name must be assigned to the PROFINET switch. To this purpose, use the function “Assign device name”,
which you can access in the Online menu with the right mouse button when the PROFINET switch is
activated.
With the “Update list” button, the network can be browsed for PROFINET participants. The PROFINET
device name can be assigned to the device with “Assign name”.
The clear identification of the PROFINET switch is ensured here by the MAC address of the device. The
MAC address of the device can be found on the device front of the PROFINET switch.
If the PROFINET switch has been assigned the correct PROFINET name, it is recognized by the PLC and
configured. If configuration has taken place correctly, the PROFINET “BF” LED is off.
The Helmholz IPSet tool, which can be downloaded at no charge from the Helmholz
website, can also be used to set the PROFINET name. Scan the following QR code to
download the IPSet tool:

4.7 Further configuration and diagnosis via the web interface
Via the web interface, the status of the PROFINET switch can
be queried and further functions can be configured.
Furthermore, a firmware update can be performed via the web
interface.
The web interface can be operated as soon as the device has a
network configuration. The IP address of the device must be
entered as URL.
In the following login dialog the username is "admin" and the
password is the serial number of the PROFINET switch which
can be read at the device side. For the first login the default
password must be changed.
Further information about the web interface can be taken
from the manual.
