What is Industrial Automation & How it Evolved
What is industrial Automation

Industrial Automation is really a technique through which we make give over human control to machines. In Everything You Need to Know About Industrial Automation Solutions are programmed to accomplish the tasks which humans accustomed to achieve. Why it is done? Because of its advantages:

Through Industrial automation we are able to do mass production with less manpower
Quality with the strategy is increased
Safety of man & equipment is increased
More accurate process control
Since human intervention is less so reliability in the system is higher
Systems operate is low energy, more electronic control so equipment our life is higher
Changes 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 method at each and every step. Human intervention was there at each 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 at the begining of 1920s. Automation was achieved by controlling air to pneumatic valves, which were actually switched on/off by relays and switches. They were very bulky and changing from the logic was very complex procedure since lots of rework was forced to accomplish difference 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 used for achieving desired industrial automation. But these systems also resulted into bulky panels. A lot of wiring was involved so time taken up 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 use of electronics space and requirements reduced, maintenance requirement reduced & systems were more reliable.
