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: Flexible OLED applications arrive

R2D2, a joint project to analyze and development high-TRL processes and technologies for manufacture of flexible organic light-emitting diodes (OLEDs) funded by the German Federal Ministry of Education and Research (BMBF) has been successfully completed.

In contrast to point light sources like LEDs made of inorganic semiconductor crystals, organic light-emitting diodes (OLEDs) are light-emitting surfaces. Their...

Im Focus: 3-D printing produces cartilage from strands of bioink

Strands of cow cartilage substitute for ink in a 3D bioprinting process that may one day create cartilage patches for worn out joints, according to a team of engineers. "Our goal is to create tissue that can be used to replace large amounts of worn out tissue or design patches," said Ibrahim T. Ozbolat, associate professor of engineering science and mechanics. "Those who have osteoarthritis in their joints suffer a lot. We need a new alternative treatment for this."

Cartilage is a good tissue to target for scale-up bioprinting because it is made up of only one cell type and has no blood vessels within the tissue. It is...

Im Focus: First experimental quantum simulation of particle physics phenomena

Physicists in Innsbruck have realized the first quantum simulation of lattice gauge theories, building a bridge between high-energy theory and atomic physics. In the journal Nature, Rainer Blatt‘s and Peter Zoller’s research teams describe how they simulated the creation of elementary particle pairs out of the vacuum by using a quantum computer.

Elementary particles are the fundamental buildings blocks of matter, and their properties are described by the Standard Model of particle physics. The...
