These features facilitate easier system configuration, for example in failsafe applications, leaner and more versatile topology architectures with multiple networked controllers and higher plant availability. The new firmware also provides improved diagnostic functions via user-definable Web pages and supports isochronous mode via Profinet.
With Shared Device, several Simatic controllers can access a Profinet input/output device, such as a distributed I/O system. This makes system configuration easier, for example in failsafe applications. It also means that both standard and failsafe CPUs can utilize the same distributed I/O system.
Intelligent Device (I-Device) allows I/O communication of a CPU to other higher-level or central controllers. Previously only hierarchical access from the central CPU to lower-level I/O devices was possible. With I-Device, leaner and more flexible topology architectures with multiple networked controllers is possible. It is easier to network controllers from several different projects, for example, or integrate Siemens controls with controllers from other manufacturers within a communication network.
The Media Redundancy Protocol (MRP) increases plant availability. This requires that the network infrastructure be installed redundantly in a ring-type topology, using Industrial Ethernet switches or via the integrated Profinet interfaces of the Simatic controllers and distributed I/O systems, for example. If communication is interrupted in one section of the ring installation, only this segment is affected without a complete plant standstill. This means that maintenance and repair work can be carried out without time pressure. The MRP protocol ensures a reconfiguration time of less than 200 milliseconds.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
