New fail-safe modules for I/O station

The Siemens Industry Automation Division has improved the performance as well as increased the functionality of the fail-safe modules for its modular Simatic ET 200M I/O station.

The new Simatic modules ET 200M 24 F-DI, ET 200M 8 F-DO and ET 200M 10 F-DO are now able to meet the requirements of the safety levels SIL 3/ Cat. 4 / PL e in mixed operation with standard modules, without the need of a safety protector.

These new modules have been equipped with PROFIsafe-Profil 2.0, enabling them to be used in Profinet networks also in connection with PN/DP couplers. In addition, an acknowledgement is possible after a voltage drop. The narrow 40-millimeter design of the ET 200M 10 F-DO is now suitable for a cable length of 1,000 meters, offers P/P switching (current sourcing) and has a switched current of two amperes per channel.

Furthermore, each new module comes with the “last valid” function, i.e. which provides the last valid state, and “energize to trip” functions, for example, to provide the last value. Such functions are especially advantageous in fire and gas applications. In the case of module ET 200M 8 F–DO with its P/M switching function (current sourcing/sinking) and switching capacity of two amperes per channel, the maximum cable length is now 200 meters.

Im Focus: Novel light sources made of 2D materials

Physicists from the University of Würzburg have designed a light source that emits photon pairs. Two-photon sources are particularly well suited for tap-proof data encryption. The experiment's key ingredients: a semiconductor crystal and some sticky tape.

So-called monolayers are at the heart of the research activities. These "super materials" (as the prestigious science magazine "Nature" puts it) have been...

Im Focus: Etching Microstructures with Lasers

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.

This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Im Focus: Light-driven atomic rotations excite magnetic waves

Terahertz excitation of selected crystal vibrations leads to an effective magnetic field that drives coherent spin motion

Controlling functional properties by light is one of the grand goals in modern condensed matter physics and materials science. A new study now demonstrates how...

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
