What is industrial Automation

Industrial Automation is really a technique in which we make give human control to machines. In industrial automation machines are designed to accomplish the tasks which people utilized to achieve. Why it is done? Because of its advantages: Through Industrial automation we are able to do mass production with less manpowerQuality from the strategy is increasedSafety of individual & devices are increasedMore accurate process controlSince human intervention is less so reliability of the system is higherSystems operate is low power supply, more electronic control so equipment life's higherChanges in process logic becomes easier since logics are changed mostly through software

How industrial automation control system Evolved?

Initially automation was achieved through manual control, operators utilized to control the task at every step. Human intervention was there at each step. http://loxahatcheegrovesveterinaryclinic.com/members/lawsontalley5/activity/157315/ were poor output, errors linked to 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 at the begining of 1920s. Automation was achieved by controlling air to pneumatic valves, which in turn were actually switched on/off by relays and switches. They were very bulky and changing with the logic was very complex procedure since a great deal of rework was needed to accomplish change in logic. So time delivered to complete task changes was very high

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 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 utilization of electronics space as well as requirements reduced, maintenance requirement reduced & systems were more reliable.
