A Profinet-compatible switch in a slim-line housing

Phoenix Contact has added a compact version to its range of switches for Profinet systems. The new FL SMN 8TX-PN with eight 10/100 Mbps copper ports can be configured and diagnosed using the Profinet Device function in PC Worx and Step 7 engineering tools.

Thanks to automatic LLDP topology detection and the MRP redundancy mechanism, the switch is suitable for use with Conformance Class B Profinet networks.

The switches can be used in both Profinet and EtherNet/IP networks. During initial start-up, the operating mode that contains the relevant functions of the particular protocol is activated by simply pressing a button.

The switches support the Media Redundancy Protocol (MRP) according to IEC 62439; for this, any device can act as a Media Redundancy Manager (MRM) via an MRM plug. Furthermore, an interchangeable configuration memory module guarantees fast device replacement when a fault or malfunction occurs. In EtherNet/IP applications, the switches support the filter function based on IGMP snooping.

Phoenix Contact is is also offering new rugged managed switches for deployment in 19in racks. The new switches are designed for extreme electromechanical and climatic conditions and fully comply with the IEC 61850-3 and IEEE 1613 requirements for deployment in energy systems.

The switches provide fan-less operation and can handle a wide temperature range extending from -40 °C to +70 °C. Redundant power supplies offer additional system stability and permit maintenance and replacement during live operation.

Despite a high port count of 28 Ethernet ports, the units only take up one rack unit in the switching cabinet. Depending on requirements, the switches are available with copper or fibre-optic ports.
