Part number:

Description
The modules below have a fixed factory-set MAC address.

  • S7-300 and S7-400 Industrial Ethernet CPs
  • S7-300 and S7-400 CPUs with integrated PROFINET interface
  • Network components like SCALANCE X, SCALANCE W, SCALANCE S, PN/PN coupler
  • Gateways like IE/PB Link, IWLAN/PB Link and IE/AS-Interface Link
  • Interface modules of ET 200M, ET 200pro and ET 200S
  • ET 200eco PN

The first 3 bytes of the MAC address describe the manufacturer ID, also known as the OUI (Organizationally Unique Identifier).
Up to now these modules above have been delivered with a MAC address in which the first three bytes have always been 08-00-06.

The manufacturer ID of the MAC addresses is administered by the IEEE (Institute of Electrical and Electronics Engineers). At the link below you can see which manufacturer ID or OUI the first three bytes of a MAC address describe.

IEEE-Standards Association

SIEMENS AG uses the following manufacturer IDs or OUIs for the MAC addresses of the above-mentioned network-compatible devices.

  • 08-00-06 (hex)
    SIEMENS AG
    Siemens IT Solutions and Services, SIS GO QM O
    Siemensstraße 2-4
    POB 2353 Fürth 90713
    GERMANY
  • 00-0E-8C (hex)
    Siemens AG A&D ET
    Siemensstraße 10
    Regensburg 93055
    GERMANY
  • 00-1B-1B (hex)
    Siemens AG
    I IA SC EWK PU1, Östliche Rheinbrückenstraße 50
    76181 Karlsruhe, Baden Württemberg
    GERMANY

Confusion may arise in the following situations:

  • A network engineer uses a new module whose factory-set MAC address has the manufacturer ID 00-0E-8C or 00-1B-1B. From older modules he is used to factory-set MAC addresses having the manufacturer ID 08-00-06. Therefore he will look for a MAC address 08-00-06-xx-yy-zz which, however, he will not find.
  • Spare parts scenario: A module with a factory-set MAC address of 08-00-06-xx-yy-zz is defective and has to be replaced with a new module. It might be that the factory-set MAC address of the new module has the manufacturer ID 00-0E-8C or 00-1B-1B.
