Motion Control: B&R Industrial Automation has achieved an intelligent sensor/actuator by integrating IO Link in the X20 System. This is made possible by the X20 digital module DS4387. All four channels are IO Link channels, but can also be used as standard inputs or outputs. The specified three-line connection can be implemented thanks to the connector system with 12 terminal points per module that is only available with X20. All specified baud rates are also supported.
IO Link is based on an intelligent point-to-point connection from the I/O module to a sensor or actuator. A simple three-line connection for conventional wiring is used for connecting a conventional device to the controller’s IO Link terminals. The channel runs in normal mode like before, simply digital. IO-Link-capable end devices utilize the benefits of this system, e.g. for transferring parameter data or even for cyclic analog data communication.
By experimenting with the photovoltaic reaction in solar cells, researchers at MIT have made a breakthrough in energy efficiency that significantly pushes the boundaries of current commercial cells on the market.
We looked at a number of sources to determine this year's greenest cars, from KBB to automotive trade magazines to environmental organizations. These 14 cars emerged as being great at either stretching fuel or reducing carbon footprint.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
