2Introduction
The managed FLEXtra PROFINET-Switch FO can be used to connect PROFINET components at 100 Mbps
as well as Ethernet devices at up to 1000 Mbps. The FLEXtra PROFINET-Switch 10-Port FO has 8 RJ45
ports with up to 1000Mbps and 2 SFP ports for fiber optic transmission with 1000 Mbps.
The supported PROFINET protocols, such as LLDP, DCP or diagnostic alarms, can be easily parameterized
and managed via the integration of a GSDML file.
In addition to the PROFINET functions, further network management functions are available in the
FLEXtra PROFINET-Switch, which can be configured via the web interface. These include VLAN, SNMP,
port mirroring, QoS/CoS mapping.
The functional design with the smart arrangement of the Network connection ports saves space in the
control cabinet. The status LEDs on the top of the FLEXtra PROFINET switch, which are always clearly
visible, enable easy diagnostics even with full cabling.

The website can also be used to query extensive information about the status of the FLEXtra PROFINET-
Switch, such as port status and statistics, stored MAC addresses and the ARP table.
The configuration set via the web interface can be downloaded or saved to an SD card as a backup or for
series commissioning.
Further information about the network management functions, the status displays and the
configuration management can be found in the detailed manual of the FLEXtra PROFINET-Switch.
This document explains the initial commissioning of the FLEXtra PROFINET-
Switch FO with a standard use case. The latest version of the document and
the detailed manual can be found at www.helmholz.de or scan the QR code
directly.
3Preparing the PROFINET-Switch
3.1 Connecting
The FLEXtra PROFINET-Switch has a redundant power
supply. The FLEXtra PROFINET-Switch must be supplied with
24 VDC via the supplied connector plug at at least one of the
two "-/+" wide-range inputs (18 - 30 VDC).
The RJ45 sockets "X1 P1” – “X1 P8" are used to connect the
network nodes (PROFINET or Ethernet) via copper Ethernet at
up to 1000 Mbit/s.
The sockets "SFP1 / X1 P9" and "SFP2 / X1 P10" can be
equipped with SFP transceiver modules. Both SM "Single
Mode" and MM "Multi Mode" SFP modules with 1000 Mbit/s transmission rate are supported.
The housing of the PROFINET-Switch is not grounded. Please connect the functional grounding
connection (FG named FE on front) of the PROFINET-Switch correctly with the reference potential.

Quickstart Guide FLEXtra PROFINET-Switch 10-Port FO | Version 1 | 11.11.2022 5
4Setup and use
4.1 Install GSDML file
You can download the GSDML file for the FLEXtra PROFINET-Switch from the website
www.helmholz.de in the download area of the product or use the QR code shown.
Install the GSDML file "GSDML-V2.41-Helmholz-FX-PN-Switch-10-Port-FO...XML" via
the TIA Portal menu "Options" / "Manage general station description files (GSD)".
4.2 Setup in the hardware-configuration
After installation, the FLEXtra PROFINET-Switch FO is listed in the hardware catalog under "Other field
devices PROFINET IO Network Components Helmholz GmbH & Co. KG Helmholz PN-Switch"
in the hardware catalog. Insert the "FLEXtra PROFINET-Switch FO, 10-port" device into the project and
connect it to your PROFINET network.
By calling up the object properties, you must give the FLEXtra PROFINET switch a unique PROFINET
name in the project and check the IP address for plausibility.

Quickstart Guide FLEXtra PROFINET-Switch 10-Port FO | Version 1 | 11.11.2022 6
The real device must later be assigned the same name as in the project.
4.3 Setup of SFP modules
The required SFP modules can be preconfigured for SFP ports 13- 16 in the configuration. The Helmholz
SFP modules (see page 8) or an entry for any other SFP module ("Gen_SFP_xxx") are available.
If the Helmholz SFP modules are configured, the FLEXtra PROFINET switch checks whether exactly the
configured SFP module has been plugged into the specified port. If an SFP module is missing or an SFP
module of a different type is plugged, a diagnosis is triggered. Thus a wrong configuration or a wrong
cabling can be detected easily.

Quickstart Guide FLEXtra PROFINET-Switch 10-Port FO | Version 1 | 11.11.2022 7
4.4 Setting the port properties
Each port of the PROFINET switch can be individually configured.
“Activate this port”
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”
„TP 1000 Mbit/s Vollduplex“
Fixed presetting of the transmission rate.
The option "TP 100 Mbit/s full duplex" is recommended when
connecting 100 Mbit/s 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.

Quickstart Guide FLEXtra PROFINET-Switch 10-Port FO | Version 1 | 11.11.2022 8
4.5 Use of SFP modules
Up to four SFP transceivers can be plugged into the FLEXtra
PROFINET switch FO (SFP1/SFP2). Each SFP transceiver is a
separate port in the switch (ports 9 and 10).
The FLEXtra PROFINET Switch FO has no manufacturer
lock-in, i.e. SFP modules from any manufacturer can be used
(see below for restrictions).
However, since there are a large number of manufacturers
and SFP transceivers on the market, we cannot provide a
functional guarantee for all transceivers.
Helmholz offers the following SFP transceiver modules tested with the FLEXtra PROFINET Switch FO:
700-997-1AM01 SFP Transceiver 1000 Mbps, single mode1310 nm, LC-Anschluss, up to 10 km
700-997-1AN01 SFP Transceiver 1000 Mbps, single mode1310 nm, LC-Anschluss, up to 40 km
700-998-1AD01 SFP Transceiver 1000 Mbps, multimode850 nm, LC-Anschluss, up to 500 m
700-998-1AG01 SFP Transceiver 1000 Mbps, multimode1310 nm, LC-Anschluss, up to 2 km
Please ensure that an SFP transceiver with the same technical data is used on the opposite side of the fiber
optic connection.
The FLEXtra PROFINET switch FO currently only supports SFP transceivers with a transmission
speed of 1000Mbit/s.
The FLEXtra PROFINET switch FO does not support SFP+ transceivers.
To plug in a SFP transceiver, the protective cap on the SFP slot must be removed. Please keep the
protective cap in case the SFP transceiver is removed again. The protective cap prevents dirt from
contaminating the empty SFP slot, which could lead to malfunctions.
SFP transceivers can also be plugged in when the FLEXtra PROFINET switch FO is powered and the
other ports are in operation. The switch automatically detects newly inserted SFP modules and puts
them into operation.
The port properties correspond to those of the RJ45 ports (see page 7). However, currently only
1000Mbit/s can be used as transmission speed for SFP port and autonegotiation is not available for FO.

4.6 Assign the PROFINET switch a name
When the configuration of the FLEXtra PROFINET-Switch FO has been completed in the hardware
configurator of the engineering tool, it can be loaded into the PLC.
In order that the FLEXtra PROFINET-Switch FO 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 FLEXtra 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 FLEXtra 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:
