A new firmware, with Profinet functions such as isochronous mode, I Device, Shared Device and Media Redundancy Protocol, and an integrated web server expand the functionality and application fields of the controllers significantly. In addition, the S7-400 controller family has been supplemented by the new CPU 412-2 PN/DP for the lower performance segment. On the Simatic S7-300 the working memory and performance of the CPU 319-3 PN/DP have been increased.
The upgraded CPU 319-3 PN/DP of the Simatic S7-300 controllers now has considerably more working memory and performance than its predecessor version. Equipped with two Profinet ports and a working memory of 2 megabytes (2.5 megabytes in the fail-safe version), the CPU now achieves a bit processing time of four nanoseconds, i.e. a computing speed that is two and a half times faster. The new CPU 412-2 PN/DP for the Simatic S7-400 controllers is provided with a variety of communication functions and is designed for the lower performance segment. Furthermore, the working memory capacity of the CPUs 414 and 416 has been increased.
The new firmware V 3.2 for the S7-300 controllers and V 6.0 for S7-400 controllers provide enhanced options in system design and simplified maintenance and diagnostics functions. The firmware incorporates the Profinet functions isochronous mode, I Device, Shared Device and Media Redundancy Protocol, as well as a web server with user-definable web pages. The new firmware is available for the Profinet controllers CPU 319-3 PN/DP, 315/317-2 PN/DP and their fail-safe variants CPU 315F-2 PN/DP and CPU 317F-2 PN/DP, as well as for the new S7-400 controllers CPU 412-2 PN/DP and the CPUs 414/416-3 PN/DP.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...
Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
