The new software version V6.1 now features a “Maintenance Override” function for maintenance operations.
Automatically generated faceplates enable the user to place bypasses in the safety program which can be mutually interlocked if necessary. Bypasses can be placed both at individual and at groups of up to three process signals. It is also possible to set a reset time so the bypasses automatically reset on expiry of the prescribed time period.
Simatic S7 F Systems is an engineering tool that is provided with safety-related function blocks certified by the German Technical Inspectorate (TÜV). The function blocks are interconnected by the user simply in CFC (Continuous Function Chart) to create a safety-related program for the fault-tolerant Simatic S7-400H controller. This solution is especially suitable for safety-related applications up to SIL3 according to IEC 61508 and IEC 61511 in the process industry.

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...
Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales
Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity...
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...
