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.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
