Information control: OLEDs show promise for rugged HMIs Liquid crystal displays (LCDs) are a common and effective human machine interface (HMI) display technology, but they have some limitations. They can have trouble operating at low temperatures, require a significant amount of energy to run, and need a backlight under certain conditions. One newer technology that holds promise is organic light emitting diodes, or OLEDs. Alarm management: Tool eases creation, management of alerts A supplier of software products and engineering consulting services for the process industries has released Operator Alert, a Web or Windows interface for creating and editing alerts for process operations. Alerts can be based on process conditions or timers, and the tool works with...
Protection: PLC output modules provide automatic fault protection AutomationDirect's line of DirectLogic option modules now includes new fault-protected output modules designed for the company's DL205 PLCs. The F2-16TDxP 16-channel direct current output modules, available in sinking and sourcing configurations, feature 16 input points which are automatically assigned as fault status indicators for the corresponding outputs. Equipped with... Hybrid control systems: Advances in simulation, tools predicted In the June 2008 North American edition of Control Engineering, author Krzysztof Pietrusewicz, PhD, discusses the aspects of complex control that make a hybrid system—hierarchical organization of discrete and continuous states, and multitasking processes with different sampling times—and describes how statecharts are a very convenient way to model the hybrid control system.
Development: Maple 12 provides CAD connectivity, new analysis tools Upon introduction of Maple 12, the latest version of Maplesoft's tool to solve complex mathematical problems and create technical documents, CEO Jim Cooper said he was providing "a bold new set of features to dramatically extend the analytical reach of engineers." Many of the new features break new ground, he said, and they "set the stage for great levels of analytical productivity." A new collection of dynamic systems modeling tools, important for control design and signal processing, has been added, as has direct connectivity between Maple 12 and computer-aided design (CAD) systems from SolidWorks and Autodesk Inventor. Development: Partners provide Matlab extensions Control engineers and others needing powerful tools for optimization, modeling, and simulation have some new choices to extend their use of Matlab from The Mathworks, Natick, MA. CoWare has partnered with Agility Design Solutions, Inc. to accelerate the simulation and implementation of complex DSP algorithms starting from Matlab models. The Numerical Algorithms Group has provided a new... In print: From June 2008, electrical CAD, steam plant anatomy, PLC for motion control
