Ethernet via two-wire cabling for new and existing systems

10.03.2014
  • Using two-wire cabling for Ethernet with the MM992-2VD media module
  • Low-cost solution for upgrading existing cabling infrastructure, such as for migrating Profibus to Profinet
  • Ethernet data transfer over distances of up to 1,000 meters

The new MM992-2VD (Variable Distance) media module from Siemens enables the use of two-wire cabling, such as Profibus cables, for Ethernet communication, without the need for additional hardware such as modems.


The MM992-2VD media module permits the transfer of data across distances of up to 1,000 meters. The bandwidth depends on the length and quality of the cable, but as a general rule, bandwidths of 100 Mbit/s can be implemented at a distance of 500 meters, and cables of 1,000 meters in length have bandwidths of 10 Mbit/s.

Cables are connected to the media module via an RJ45 connector. The MM992-2VD media module can be used with all modular switches in the Scalance X-300 range, as well as with the Scalance S627-2M security module.

With the MM992-2VD media module, existing cable infrastructure within machinery and plants is able to be converted to an Ethernet network quickly and economically. This solution, developed by Siemens, represents an uncomplicated method of migrating to Profinet, particularly in view of the wide use of Profibus cabling.

In addition, the media module can be used within Ethernet networks to extend the maximum Ethernet cable length for bandwidths of 100 Mbit/s as defined in the standard - the MM992-2VD enables the simple integration of remote network nodes into plant networks at distances of over 100 and up to a maximum of 300 meters using standard copper cables instead of the glass fiber optic cables previously necessary for such Ethernet connections.

Im Focus: Lasers are the key to mastering challenges in lightweight construction

Many joining and cutting processes are possible only with lasers. New technologies make it possible to manufacture metal components with hollow structures that are significantly lighter and yet just as stable as solid components. In addition, lasers can be used to combine various lightweight construction materials and steels with each other. The Fraunhofer Institute for Laser Technology ILT in Aachen is presenting a range of such solutions at the LASER World of Photonics trade fair from June 22 to 25, 2015 in Munich, Germany, (Hall A3, Stand 121).

Lightweight construction materials are popular: aluminum is used in the bodywork of cars, for example, and aircraft fuselages already consist in large part of...

Im Focus: Solid-state photonics goes extreme ultraviolet

Using ultrashort laser pulses, scientists in Max Planck Institute of Quantum Optics have demonstrated the emission of extreme ultraviolet radiation from thin dielectric films and have investigated the underlying mechanisms.

In 1961, only shortly after the invention of the first laser, scientists exposed silicon dioxide crystals (also known as quartz) to an intense ruby laser to...

Im Focus: Advance in regenerative medicine

The only professorship in Germany to date, one master's programme, one laboratory with worldwide unique equipment and the corresponding research results: The University of Würzburg is leading in the field of biofabrication.

Paul Dalton is presently the only professor of biofabrication in Germany. About a year ago, the Australian researcher relocated to the Würzburg department for...

Im Focus: Basel Physicists Develop Efficient Method of Signal Transmission from Nanocomponents

Physicists have developed an innovative method that could enable the efficient use of nanocomponents in electronic circuits. To achieve this, they have developed a layout in which a nanocomponent is connected to two electrical conductors, which uncouple the electrical signal in a highly efficient manner. The scientists at the Department of Physics and the Swiss Nanoscience Institute at the University of Basel have published their results in the scientific journal “Nature Communications” together with their colleagues from ETH Zurich.

Electronic components are becoming smaller and smaller. Components measuring just a few nanometers – the size of around ten atoms – are already being produced...
