2. PROGRAMMABLE LOGIC CONTROLLERS 2.1 INTRODUCTION Control engineering has evolved over time. In the past humans were the main method for controlling a system. More recently electricity has been used for control and early electrical control was based on relays. These relays allow power to be switched on and off without a mechanical switch. It is common to use relays to make simple logical control decisions. The development of low cost computer has brought the most recent revolution‚ the Programmable

A REPORT ON AUTOMATION OF CONVERTOR TILTING DRIVE USING PLC AND VVVF DRIVES Abstract: Industry is a home of various kinds of machines that are used for numerous processes and treatments. The control and working of these machines have been automated through the use of PLCs. Automation has resulted in faster production rate‚ increased accuracy‚ better quality and reduced faults and human errors. PLCs and VVVF drives are used in most of the sections and units at VISL because of their simple methods

Thirty-six years ago‚ on August 3‚ 1981‚ more than 12‚000 members of the Professional Air Traffic Controllers Organization (PATCO) walked out‚ releasing multiple events that has since redefined labor unions. In rejoinder to the walkout‚ President Ronald Reagan delivered one of the crucial statements of his term. He said the striking air-traffic controllers were in desecration of the law; if they did not report to work within 48 hours‚ they would be fired. Long after Reagan’s presidency‚ tensions

CHAPTER II: THEORETICAL FRAMEWORK 2.1 Introduction In this fast-paced era‚ the need for faster‚ reliable and more convenient systems increases in any aspects of the society. Certain problems exist such as the slow manual sales system of some evolving business firms‚ effective reduction of the number of vehicular accidents that occur‚ security problems in some establishments or even in parking areas and more. One of the reasons why these problems arise is the lack of innovations that is why automated

Copy No: 1 of 5 Total Pages: 26 USE OF PROGRAMMABLE LOGIC CONTROL IN MODERN VEHICLE INTRODUCTION. 01. Programmable logic controllers (PLCs) have become the most predominant control elements for the discrete event control of a mechatronics system. Simplification of engineering and precise control of mechanical or manufacturing process can result in significant cost savings. The most effective way which can pay big dividends in the long run is flexible automation; a planned

employees of the Professional Air Traffic Controller Organization (PATCO). It stood out as an event of unmatched worth during the labor decline era. The PATCO strike was among the expensive in the United States. Although‚ the PATCO strike was not the largest in history for America‚ it was substantial enough to involve eleven thousand air traffic controllers employed by the Federal Aviation Administration (FAA). The Professional Air Traffic Controller Organization was originated in 1968 with support

Introduction Have you thought about installing a home security system‚ but put it off because you don’t think you really need one? Well‚ before you put it off any longer‚ you may want to consider these facts: In 2010‚ there were more than two million home burglaries in the United States‚ over 70 percent of which took place in residential homes‚ reports the Federal Bureau of Investigation (FBI). Victims of these burglaries claimed an estimated $4.6 billion in lost property‚ and the average dollar
