Siemens expands Industrial Ethernet portfolio with fault-tolerant redundancy solution

23.01.2012
The Siemens Industry Automation Division has expanded its portfolio of industrial network products with a fault-tolerant system solution for smooth and thus delay-free redundancy in Industrial Ethernet networks.

The new Scalance X-200RNA (Redundant Network Access) network access points have been designed for all applications and sectors in which a network connection with particularly high fault tolerance is required. In addition to the Scalance hardware, Siemens also offers the Softnet-IE RNA software package with which PCs can be connected to parallel networks.


The Siemens Industry Automation Division has expanded its portfolio of industrial network products with Scalance X-200RNA, a fault-tolerant system solution for smooth redundancy in Industrial Ethernet networks.

The Siemens Industry Automation Division offers a redundant solution based on the Parallel Redundancy Protocol (PRP) in accordance with the IEC 62439-3 standard. The X-200RNA Scalance access points connect one or two network segments or data terminals without PRP functionality over two parallel networks without delay. An access point duplicates the transmitter's message frame and feeds a copy into each of the connected networks. The two LANs can have different structures – star, ring or tree. At the receiver end, the second access point passes on the first message frame which arrives to the addressees.

The message frame which arrives subsequently from the other LAN is discarded. The two separate networks and the PRP procedure guarantee secure and punctual transmission. A reconfiguration time as required by other redundancy procedures using only one physical network is therefore superfluous. Typical areas of application for fault-tolerant redundant connections can be found in the energy sector as well as in process automation, for example in the pharmaceutical or chemical industries.

Siemens offers the new access points as Scalance X204RNA in a plastic enclosure with four electric RJ45 ports as well as Scalance X204RNA EEC (Enhanced Environmental Conditions) in a metal enclosure with two electric ports and two electric/optical combined ports for SFP (Small Form-Factor Pluggable) transceivers and wide-range power supplies. Various information for network diagnostics is available via SNMP (Simple Network Management Protocol).

The Softnet-IE RNA software package can be used for linking PCs at low cost into redundant, parallel network topologies based on PRP without additional programming overheads. Using the Siemens software, a computer can establish the same smooth redundancy connection over two LAN networks as the Scalance X-200RNA network access points.

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...

Im Focus: Scientists improve forecast of increasing hazard on Ecuadorian volcano

Researchers from the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science, the Italian Space Agency (ASI), and the Instituto Geofisico--Escuela Politecnica Nacional (IGEPN) of Ecuador, showed an increasing volcanic danger on Cotopaxi in Ecuador using a powerful technique known as Interferometric Synthetic Aperture Radar (InSAR).

The Andes region in which Cotopaxi volcano is located is known to contain some of the world's most serious volcanic hazard. A mid- to large-size eruption has...
