What is <a href="">How to Choose Programmable RGB LED Controller</a> is a technique through which we make give over human control to machines. In industrial automation machines are developed to accomplish the tasks which humans used to achieve. Why it is done? Because of its advantages:<br/><br/> Through Industrial automation we are able to do mass production with less manpower<br/> Quality of the method is increased<br/> Safety of man & equipment is increased<br/> More accurate process control<br/> Since human intervention is less so reliability of the system is higher<br/> Systems operate is low power, more electronic control so equipment every day life is higher<br/> Changes in process logic becomes easier since logics are changed mostly through software<br/><br/>Principal Industrial Automation MNCs<br/><br/> L & T • ALSTOM<br/><br/> Schneider • FESTO<br/><br/> Siemens • Fuji Electric<br/><br/> Allen Bradley • Toshiba<br/><br/> Messung • TATA Honeywell<br/><br/> Modicon • Omron<br/><br/> Mitsubishi • Fanuc<br/><br/> Asia Automation • Delta<br/><br/>How industrial automation control system Evolved?<br/><br/>Initially automation was achieved through manual control, operators accustomed to control the process each and every step. Human intervention was there at each and every step. Drawbacks were low quality output, errors involved with human involvement affected compromised safety, wastage of raw material, and accuracy of human action.<br/><br/>Then came Pneumatic Control: Industrial automation on this era was achieved through invention of pneumatic controllers noisy . 1920s. Automation was achieved by controlling air to pneumatic valves, which were actually switched on/off by relays and switches. They were very bulky and changing with the logic was very complex procedure since lots of rework was necessary to accomplish change in logic. So time taken to complete task changes was very high<br/><br/>Hard wired logic control: contactors, relays (for switching), timers and counters (for timing and counting) were chosen for achieving desired industrial automation. But these systems also resulted into bulky panels. A lot of wiring was involved so time taken up complete task was higher. Defect investigation & troubleshooting was complex.<br/><br/>Electronic Control using Logic Gates: In early 60s electronics dominated the procedure, electronic logic gates were utilized for achieving logical operations. they replaced switching devices like relays and contactors inside the control circuits. Electronic times & counters replaced mechanical timers & counters. Due to using electronics space as well as requirements reduced, maintenance requirement reduced & systems were more reliable.
