Pre-assembled, plug-and-play Key Panels with safety functionality

With the Simatic HMI KP32F PN, the Siemens Industry Automation Division has expanded its family of Key Panels with a control panel featuring 32 large, freely-configurable keys with LED backlighting.

Tactile feedback when keys are pressed, free configuration of the key functions, as well as bright LEDs in one of five colors all provide a high degree of user friendliness. The costly and time-consuming individual assembly and wiring overhead associated with conventional operator controls is eliminated.

Keys not currently required can subsequently be configured at any time, such as when an application is extended, for example. The new key panel is designed in the IP65 degree of protection for use in a rough industrial environment and is also suitable for safety-related applications. The device features four fail-safe inputs to which one or two emergency stop buttons can be connected in accordance with safety category SIL 3.

The new Simatic HMI KP32F PN Key Panel is equipped with two Profinet interfaces. This means that the panel can be integrated into existing networks without the need for additional hardware components, such as switches. The 32 keys are freely configurable: Flashing LEDs can prompt operator interaction, for example, or changing colors can indicate the machine status in red, yellow, green, white or blue. In addition the intensity of the LED backlighting of the keys can be adjusted to suit ambient conditions, so that excellent readability is ensured even under difficult lighting conditions such as extreme brightness. Slide-in strips can be used for individual labeling of the keys.

Typical fields of application for key operator panels are applications that require the deterministic transmission of operator commands. Compared to individual HMI elements such as key-operated switches or illuminated pushbuttons, pre-assembled, plug-and-play operator panels save time-consuming assembly and wiring.

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...
