Failsafe, wireless operator control and monitoring via Rapid Roaming

16.04.2010
The Siemens Industry Automation Division has improved the performance and equipment of its portable devices for wireless operator control and monitoring of machinery and plants, as well as enhancing them with additional functions.

For safety-oriented applications, the Mobile Panel 277F IWLAN communicates via a "Rapid Roaming" process in order to ensure interruption-free transmission of the wireless signals. Optimization measures in the Mobile Panel 277 IWLAN and Mobile Panel 277F IWLAN for safety-related applications include color display of the WLAN signal strength with an additional vibration alarm, which is triggered when a specific lower limit threshold is violated. Handling of the enabling button has also been improved.


For safety-oriented applications, the 277F IWLAN Mobile Panel communicates by means of the extended WLAN access procedure iPCF-MC (Industrial Point Coordination Function with Management Channel), also known as "Rapid Roaming". This ensures fast handover of the radio signals between access points and interruption-free roaming times - a basic requirement for mobile operator control and monitoring in safety-related areas where enabling and emergency stop buttons are used. The Mobile Panel 277F IWLAN is suitable for use in a Profinet-based network with a Profisafe profile and IWLAN infrastructure with Scalance W access points from Siemens.

The configuration of the Industrial WLAN connection has been simplified for both new Siemens panels with a software wizard available via web interface. Multiple wireless approvals mean that the devices can be used all over the world. The Mobile Panel 277 IWLAN without safety functions is also suitable for applications with the Simotion motion control system.

One of the new failsafe Mobile Panel 277F IWLAN variants utilizes economical Moby D Smart Cards for site localization, with logging on to the appropriate operating area on an RFID (Radio Frequency Identification) tag instead of a transponder. A typical application here is in security-compliant robot cells.

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Im Focus: Visual intelligence is not the same as IQ

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.

During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....

Im Focus: Researchers Develop Data Bus for Quantum Computer

The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.

Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...

Rice University researchers test 3-D carbon nanostructures' thermal transport abilities

Pillared graphene would transfer heat better if the theoretical material had a few asymmetric junctions that caused wrinkles, according to Rice University...
