What is industrial AutomationIndustrial? Automation is a technique through which we make hand over human control to machines. In industrial automation machines are designed to accomplish the tasks which human beings utilized to achieve. Why it is done? Because of its advantages: Through Industrial automation we will do mass production with less manpower Quality of the strategy is increased Safety of man & tools are increased More accurate process control Since human intervention is less so reliability in 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 used to control the process at each step. Human intervention was there at every step. Drawbacks were inferior output, errors involved with human involvement affected compromised safety, wastage of raw material, and accuracy of human action.Then came https://idealprocessandautomation.com.au/ : Industrial automation with this era was achieved through invention of pneumatic controllers in early 1920s. Automation was achieved by controlling air to pneumatic valves, which experts claim were actually switched on/off by relays and switches. They were very bulky and changing in 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 come to complete task was higher. Defect investigation & troubleshooting was complex.Electronic Control using Logic Gates: In early 60s electronics dominated the method, electronic logic gates were utilised 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 utilization of electronics space and requirements reduced, maintenance requirement reduced & systems were more reliable.
