What is industrial AutomationIndustrial? Automation is a technique by 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 its advantages: Through Industrial automation we're able to do mass production with less manpower Quality with the strategy is increased Safety of individual & devices are increased More accurate process control Since human intervention is less so reliability with the system is higher Systems operate is low power source, 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 accustomed to control the procedure at each and every step. https://idealprocessandautomation.com.au/ was there each and 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 in this era was achieved through invention of pneumatic controllers in early 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 with the logic was very complex procedure since a lot of rework was necessary to accomplish alternation in logic. So time taken up complete task changes was very highHard wired logic control: contactors, relays (for switching), timers and counters (for timing and counting) were utilised for achieving desired industrial automation. But these systems also resulted into bulky panels. A lot of wiring was involved so time delivered to complete task was higher. Defect investigation & troubleshooting was complex.Electronic Control using Logic Gates: In early 60s electronics dominated the procedure, electronic logic gates were used 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 usage of electronics space and requirements reduced, maintenance requirement reduced & systems were more reliable.
