What is industrial Automation

Industrial Automation can be a technique by which we make pay human control to machines. In industrial automation machines are programmed to accomplish the tasks which human beings accustomed to achieve. Why it is done? Because of its advantages: Through Industrial automation we could do mass production with less manpowerQuality of the strategy is increasedSafety of person & tools are increasedMore accurate process controlSince human intervention is less so reliability of the system is higherSystems operate is low power, 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 accustomed to control the process each and every step. Human intervention was there each and every step. Drawbacks were poor 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 in turn were actually switched on/off by relays and switches. They were very bulky and changing from the logic was very complex procedure since a lot of rework was needed to accomplish alteration of logic. So time taken up complete task changes was very high

Hard wired logic control: contactors, relays (for switching), timers and counters (for timing and counting) were used 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. https://decontruction.wiki/wiki/What_is_Industrial_Automation_How_it_Evolved & 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 in the control circuits. Electronic times & counters replaced mechanical timers & counters. Due to use of electronics space and energy requirements reduced, maintenance requirement reduced & systems were more reliable.
