The two new basic devices Logo!12/24 RCE and Logo!230 RCE with communication and network capabilities enhance the Siemens portfolio with logic modules geared to meeting demanding applications. The performance of the new basic devices has also been significantly improved, for example the program capacity has been doubled to 400 function blocks, and a wide range of new practice-oriented functions has been introduced.
Up to eight of the new logic modules can be networked using standard Ethernet switches. The logic modules can be used in a master/master mode where all devices have a separate program and exchange the required information via Ethernet. In master/slave mode, a master executes the program and uses the other logic modules for additional I/O (input/output) expansion. Each individual Logo! device can already be extended by I/O modules. To facilitate handling of the increased number of inputs/outputs now available in the application, the program memory has been doubled to 400 function blocks compared to the standard devices. This is an advantage in building automation, for example, if a large number of shutters have to be controlled centrally.
Further improved features of the new Logo! devices are a "super capacitor" which buffers the integral real-time clock for 20 days in the event of a power supply failure, and the option for data storage on a standard SD card. This card can be used to copy programs and also for saving data or projects, including comments. The data logging function is also new. This can now be used, for example, to document temperature patterns or levels. Recording in the internal memory or on the external SD card is either time-controlled or event-controlled, and can be used for documentation and evaluation purposes.
New function blocks determine minimum and maximum values, generate mean values, or execute a stopwatch function with which, for example, the duration of production processes can be measured very easily. This is supplemented by an astronomical time switch which is triggered by sunrise and sunset. This helps to save energy in illumination systems or optimize feeding times with livestock breeding. A new analog filter minimizes the influence of interfering pulses. In the case of repeated program sequences, for example the control of shutters, users can now generate macros, save these in macro libraries, and recall them from there as often as required.
The new Logo! basic devices with Ethernet interface expand the Siemens portfolio by logic modules for demanding applications. The previous standard devices are still used for basic applications. The programs of the new Logo! modules are fully compatible with those of the standard devices. They have the same built-in display, cursor keys, and field wiring connections as the standard devices. Furthermore, all existing expansion modules can be used on the new logic modules, including the external Logo! text display.

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...
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...
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...

Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.
Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
