FLEXtra PROFINET-Switch FO – 10-Port

The FLEXtra PROFINET-Switch connects the control world with PROFINET according to Conformance Class B and the IT world with up to 1GBit Ethernet.

The managed FLEXtra PROFINET switch FO can be used to network PROFINET components with 100 Mbps as well as Ethernet nodes with up to 1000 Mbps. The FLEXtra PROFINET switch FO has 8 RJ45 ports with up to 1000 Mbps and 2 SFP ports for fiber transmission with 1000 Mbps.

Thus, communication from the control level and the machine or the mixing of Ethernet and PROFINET components in one switch is possible. PROFINET prioritization according to Conformance Class B of the machine components is always guaranteed.
In addition to PROFINET, functions such as SNMP, NTP, VLAN, port mirroring, QoS/CoS mapping and extensive statistics are available for managing the Ethernet network.

The practical design with the intelligent arrangement of the Ethernet sockets saves space in the control cabinet. The status LEDs on the top of the FLEXtra PROFINET switch, which are always clearly visible, allow for easy diagnostics even when fully wired.
One of the most important functions of a PROFINET switch is the prioritization of PROFINET telegram traffic in the machine network. The managed switch can distinguish whether the telegram is a web request, an FTP file transfer, a media stream, or a PROFINET telegram. In the event of a high transmission load, the important telegrams can thus be prioritized to prevent telegram losses of the machine components. The supported PROFINET protocols, such as LLDP, DCP or diagnostic alarms, can be easily parameterized and managed.

Technical advantages when using a PROFINET-Switch:

  • Prioritizing of PROFINET frames
  • Assignment of a configuration via the device name
  • Neighborhood detection
  • Device exchange without programming device
  • Ring redundancy
  • Each port can be activated or deactivated
  • Diagnostic messages for network problems
  • Identification and maintenance data



  • 8-Ports Ethernet RJ45 with 10/100/1000 Mbit/s
  • 2-Ports for SFP-Transceivers with 1000 MBit/s, Single-mode or Multi-mode
  • Practical design for optimized cable routes
  • PROFINET Conformance Class B (100 Mbps)
  • Integration into the automation network with GSDML file
  • Fast and easy configuration and diagnostics via PROFINET and web interface
  • LLDP, DCP, diagnostic alarms
  • Media redundancy: MRP client
  • SNMP, VLAN, Cos/QoS mapping, NTP, port mirroring
  • Network statistics (frames, errors)
  • SD memory card for configuration
  • Redundant power supply unit
