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: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
