Siemens extends Industrial Ethernet portfolio with high-availability redundancy solution for ring topologies

13.11.2012
The Siemens Industry Automation Division is extending its portfolio of industrial network products to include high-availability system solutions for seamless, delayfree redundancy in Industrial Ethernet networks.

The new Scalance X- 200RNA (Redundant Network Access) network access points are designed for all applications and industries in which network connection with a high level of availability is required.



The Siemens Industry Automation Division offers two redundant solutions based on the Parallel Redundancy Protocol (PRP) and High-availability Seamless Redundancy Protocol (HSR) in accordance with the IEC 62439-3 standard.

Alongside a version for parallel PRP networks, a version for ring HSR network topologies is now also available.

The Scalance X-200RNA access points for PRP networks connect up to two network segments or data terminals with no PRP functionality without delay over two parallel networks. In ring network topologies, the HSR technique permits seamless data transmission to be achieved for high-availability systems, for example in process automation applications. Scalance X204RNA devices with HSR functionality can also be used for simple redundant transition from HSR to PRP network structures.

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. A variety of information for network diagnostics is available via SNMP (Simple Network Management Protocol).

With the Softnet-IE RNA software package, Siemens is also offering a solution capable of 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 seamless redundancy connection over two LAN networks as the Scalance X-200RNA network access points.

Typical areas of application for high-availability redundant connections can be found in the energy industry as well as in process automation, for example in the pharmaceutical or chemical industries.

Im Focus: Future electronic components to be printed like newspapers

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.

The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...

Im Focus: First evidence on the source of extragalactic particles

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.

To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...

Im Focus: Magnetic vortices: Two independent magnetic skyrmion phases discovered in a single material

For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...

Im Focus: Breaking the bond: To take part or not?

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.

A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...

Im Focus: New 2D Spectroscopy Methods

Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.

"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
