The controller architecture is based on the standard Profinet Asic Ertec 400 with which integrated, real-time-enabled communication can be implemented from the corporate management level right down to the process. It also enables simultaneous real-time and IT communication on one line using TCP/IP, for example.
The Profinet interface integrated on the mainboard relieves the PC processor of communication tasks and thus increases PC system performance. This also saves a slot, making it available for other PC expansion cards. The three Profinet ports allow flexible and simple establishment of linear or ring topologies, and they are used for connecting PLCs, distributed I/O, or drives to the PC.Alternatively, with real time communication (RT) the ports can be used as standard Windows interfaces for TCP/IP communication, for example, or for visualization tasks with Simatic WinCC flexible. The new version of the software PLC WinAC RTX 2008 already uses the new communication facilities of the onboard interface. The network topology is conveniently configured with Step 7 or NCM-PC.

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
