Redundant server systems for increased plant availability

06.04.2011
The Siemens Industry Automation Division presents new software for configuring redundant OPC UA servers (Openness, Productivity & Collaboration, Unified Architecture).

The S7 OPC Redundancy application allows the design of redundant server systems for fail-safe connection of HMI devices within Industrial Ethernet or PROFIBUS networks. OPC is a standardized and open interface for connecting Windows applications using various protocols such as S7-communication, Profinet and SNMP. The extended development version, OPC UA, additionally provides security and redundancy functions, for example.


Within a redundant server structure, a backup server immediately assumes the functions of the failed OPC UA server in the event of a power outage or system failure. In this way, connected clients such as HMI devices can access the central data and remain operational without interruption. The new Siemens software thus increases the availability of automation data to HMI systems. In normal operation, the clients are distributed evenly across all connected servers, providing improved utilization of IT resources.

PCs with the Windows Server operating system, Simatic Net S7 basic software, and the new S7 OPC Redundancy application are required to establish a redundant OPC UA server system. The OPC UA server is synchronized using high-performance Industrial Ethernet access points with a bandwidth of 10, 100 or 1,000 Mbit/s. No additional wiring is required. The connected OPC clients require the appropriate OPC UA support for communication. Existing standard OPC UA clients with reconnect functionality in accordance with the OPC UA specification can continue to be used.

Im Focus: Scientists present new observations to understand the phase transition in quantum chromodynamics

The building blocks of matter in our universe were formed in the first 10 microseconds of its existence, according to the currently accepted scientific picture. After the Big Bang about 13.7 billion years ago, matter consisted mainly of quarks and gluons, two types of elementary particles whose interactions are governed by quantum chromodynamics (QCD), the theory of strong interaction. In the early universe, these particles moved (nearly) freely in a quark-gluon plasma.

This is a joint press release of University Muenster and Heidelberg as well as the GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt.

Then, in a phase transition, they combined and formed hadrons, among them the building blocks of atomic nuclei, protons and neutrons. In the current issue of...

Im Focus: Patented nanostructure for solar cells: Rough optics, smooth surface

Thin-film solar cells made of crystalline silicon are inexpensive and achieve efficiencies of a good 14 percent. However, they could do even better if their shiny surfaces reflected less light. A team led by Prof. Christiane Becker from the Helmholtz-Zentrum Berlin (HZB) has now patented a sophisticated new solution to this problem.

"It is not enough simply to bring more light into the cell," says Christiane Becker. Such surface structures can even ultimately reduce the efficiency by...

Im Focus: New soft coral species discovered in Panama

A study in the journal Bulletin of Marine Science describes a new, blood-red species of octocoral found in Panama. The species in the genus Thesea was discovered in the threatened low-light reef environment on Hannibal Bank, 60 kilometers off mainland Pacific Panama, by researchers at the Smithsonian Tropical Research Institute in Panama (STRI) and the Centro de Investigación en Ciencias del Mar y Limnología (CIMAR) at the University of Costa Rica.

Scientists established the new species, Thesea dalioi, by comparing its physical traits, such as branch thickness and the bright red colony color, with the...
