The Simatic CPU 414F-3 PN/DP for the Simatic S7-400 Controller has all the functions of the standard CPU 414-3 PN/DP and is suitable – when supplied with 2.8MB of RAM – for safety-related functions in the mid-performance range. The CPU has a 2-port Profinet and an MPI/Profibus DP master interface onboard, as well as an additional plug-in Profibus DP interface. The new interface module IM 154-8F PN/DP CPU for the ET 200pro distributed I/O with its high IP 65/67 degree of protection has functions and a quantity structure similar to those of the CPU 315F-2 PN/DP for Simatic S7-300, with a 512KB RAM, a combined MPI/Profibus DP and a 3-port Profinet interface.
The new Simatic CPU 414F-3 PN/DP and IM 154-8F PN/DP CPU support Profinet IO and CBA as well as Profibus DP, plus the new Profinet functions Shared Device, i-Device and Media Redundancy. Isochronous mode via Profinet and Profibus facilitates the fast and reliable exchange of data. Via the Ethernet the integrated web server enables information, such as status and diagnostics data or clock synchronization data, to be retrieved over the Intranet / Internet. Standard and safety programs can run simultaneously on the same CPU and the CPUs are programmed with the STEP 7 engineering system. The S7 Distributed Safety option package contains a library of TÜV-certified (German Technical Inspectorate) function blocks, including functions such as emergency stop or door monitoring. Both CPUs meet the high safety requirements according to the relevant standards EN 954-1 up to Cat. 4, IEC 62061 up to SIL 3, and EN ISO 13849-1 up to PL e.

Cells need to repair damaged DNA in our genes to prevent the development of cancer and other diseases. Our cells therefore activate and send “repair-proteins”...
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...
