Motivation for This Book The OPC Foundation provides specifications for data exchange in industrial au- mation. There is a long history of COM/DCOM-based specifications, most pro- nent OPC Data Access (DA), OPC Alarms and Events (A&E), and OPC Historical Data Access (HDA), which are widely accepted in the industry and implemented by almost every system targeting industrial automation. Now the OPC Foundation has released a new generation of OPC specifications called OPC Unified Architecture (OPC UA). With OPC UA, the OPC Foundation fulfills a technology shift from the retiring COM/DCOM technology to a servi- oriented architecture providing data in a platform-independent manner via Web Service...
OPC UA: The Basics is an Everyman's overview of OPC UA. This is not a hardcore technical specification that digs down to the smallest bits and bytes of OPC UA. This is a high level overview of the protocol for someone without 20 years of experience in embedded programming. Perfect for a sales person, IT Professional or executive trying to figure out what OPC UA brings to the table. Join John Rinaldi (The Dr. Phil of Automation) as he breaks down the features of OPC UA and gives you insight into how this emerging technology is redefining the line between Automation and Enterprise Systems.
Short-listed for the Pushkin House Russian Book Prize More than twenty years ago, the NPR correspondent Anne Garrels first visited Chelyabinsk, a gritty military-industrial center a thousand miles east of Moscow. The longtime home of the Soviet nuclear program, the Chelyabinsk region contained beautiful lakes, shuttered factories, mysterious closed cities, and some of the most polluted places on earth. Garrels’s goal was to chart the aftershocks of the U.S.S.R.’s collapse by traveling to Russia’s heartland. Returning again and again, Garrels found that the area’s new freedoms and opportunities were exciting but also traumatic. As the economic collapse of the early 1990s abated, the c...
OPC significa Openess, Productivity y Collaboration, que simboliza las nuevas posibilidades que se abren en la tecnología de automatización. Como plataforma de integración, las PC ofrecen nuevas perspectivas y oportunidades para OPC, tanto en términos técnicos como económicos. Los conceptos de cliente / servidor implementados con OPC ofrecen posibilidades de acceso estandarizadas y de múltiples proveedores. La nueva especificación OPC UA (arquitectura unificada) tiene como objetivo la interoperabilidad global y define una plataforma de interoperabilidad basada en servicios web.
OPC stands for Openness, Productivity, and Collaboration, symbolizing the new possibilities opening up in automation technology. The main objective of the new OPC generation Unified Architecture is to facilitate global interoperability and to define an information and data-exchange mechanism that is service oriented, multivendor, and cross-platform capable - from the field device on the shop floor to the ERP system on the factory level. This book includes information on: - the birth, objectives, and fundamentals of OPC and OPC UA, - the technical specifications that currently exist and those that are in preparation, - the procedures for designing and implementing components, - a transparent ...
This book presents a definitive guide to understanding, applying, and teaching Occupational Performance Coaching (OPC). Grounded in principles of occupational therapy, person-centredness, and interprofessional frameworks of health and disability, this book will be of interest across health and rehabilitation professions. Supporting people affected by disability to do well and live the life they want is the ultimate outcome of all rehabilitation professionals, no matter where on the lifespan our clients sit. Coaching is increasingly recognised as highly effective in achieving this aim. This accessible manual provides case examples related to diverse health conditions alongside practitioner re...
The long-buried story of three extraordinary female journalists who permanently shattered the barriers to women covering war Kate Webb, an Australian iconoclast, Catherine Leroy, a French daredevil photographer, and Frances FitzGerald, a blue-blood American intellectual, arrived in Vietnam with starkly different life experiences but one shared purpose: to report on the most consequential story of the decade. At a time when women were considered unfit to be foreign reporters, Frankie, Catherine and Kate challenged the rules imposed on them by the military, ignored the belittlement of their male peers, and ultimately altered the craft of war reportage for generations. In You Don’t Belong Her...
Pisani shows how the U. S. added a Cold War Corollary to the principle of self-determination: massive foreign aid and nonmilitary covert operations to reshape war-torn Europe in the image of the U. S. She tells, for the first time, the story of the top CIA operatives who were instrumental in developing the non-military covert intervention policies of the early Cold War years and the Office of Policy Coordination that carried them out.
Your body is constantly being attacked by very harmful substances known as free radicals. You cannot see them, smell them, or touch them, but they are always there, trying to destroy body proteins and cell membranes. OPC's (oligomeric proanthocyanidins) are among today's most poten and promising free-radical fighters. Found in grape seeds, red wine, and the bark of French maritime pine tress, more powerful than vitamins C and E, the gold-standard among antioxidants. This book explains the benefits of OPCs in combating modern-day killer diseases and in protecting the body's billions of cells.
