RFID read/write devices with ISO functionality

Siemens´s Industry Automation Division has now redesigned its HF (high frequency) 13.56 megahertz range Simatic RF310R and RF380R RFID (radio frequency identification) read/write devices so that they can also work with ISO 15693 standard transponders (tags).

Its ISO 15693 functionality makes the RF300 system also suitable for use in applications which only need simple types of transponders with little memory, such as the inexpensive MDS D100 and D124 ISO 15693 tags.

The D324 and D160 tags in the Moby D product line have data capacities ranging from twenty bytes to one kilobyte. These are typically used in applications with central data storage in manufacturing industries, such as the automotive industry and its suppliers, and baggage handling systems, such as those in airports.

Simatic RF310R and RF380R readers are also suitable for use with more advanced tags in the RF300 transponder range. These have larger data capacities and facilitate particularly fast data communication between reader and transponder.

The mode of operation is easily switched in the Step7 program by changing the parameters in function blocks, so that the readers at the air interface can either communicate in the high-performance "RF300 protocol" mode, as before, or under the ISO 15693 protocol.

Already available standard communication modules are used to integrate these readers into PC applications or an automated system with Simatic, Profibus and Profinet. The Simatic RF380R reader has an additional RS232 interface which enables it to be connected directly to another manufacturer's control system or a PC - without needing an interface converter. The next devices to be equipped with ISO 15693 functionality will be the RF340R and RF350R readers and the RF310M mobile handheld terminal.

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...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
