What is industrial AutomationIndustrial? Automation is often a technique through which we make hand over human control to machines. In industrial automation machines are programmed to accomplish the tasks which individuals utilized to achieve. Why it is done? Because of https://idealprocessandautomation.com.au/ : Through Industrial automation we will do mass production with less manpower Quality of the product is increased Safety of person & equipment is increased More accurate process control Since human intervention is less so reliability with the system is higher Systems operate is low power supply, more electronic control so equipment our life is higher Changes in process logic becomes easier since logics are changed mostly through softwarePrincipal Industrial Automation MNCs L & T • ALSTOM Schneider • FESTO Siemens • Fuji Electric Allen Bradley • Toshiba Messung • TATA Honeywell Modicon • Omron Mitsubishi • Fanuc Asia Automation • DeltaHow? industrial automation control system Evolved?Initially automation was achieved through manual control, operators utilized to control the method at every step. Human intervention was there at every step. Drawbacks were inferior output, errors associated with human involvement affected compromised safety, wastage of raw material, and accuracy of human action.Then came Pneumatic Control: Industrial automation with this era was achieved through invention of pneumatic controllers noisy . 1920s. Automation was achieved by controlling air to pneumatic valves, which often were actually switched on/off by relays and switches. They were very bulky and changing of the logic was very complex procedure since a lot of rework was required to accomplish alternation in logic. So time taken to complete task changes was very highHard wired logic control: contactors, relays (for switching), timers and counters (for timing and counting) were utilized for achieving desired industrial automation. But these systems also resulted into bulky panels. A lot of wiring was involved so time come to complete task was higher. Defect investigation & troubleshooting was complex.Electronic Control using Logic Gates: In early 60s electronics dominated the process, electronic logic gates were utilized for achieving logical operations. they replaced switching devices like relays and contactors within the control circuits. Electronic times & counters replaced mechanical timers & counters. Due to using electronics space and energy requirements reduced, maintenance requirement reduced & systems were more reliable.
