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

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

Through Industrial automation we are able to do mass production with less manpower
Quality from the technique is increased
Safety of individual & devices are increased
More accurate process control
Since human intervention is less so reliability from the system is higher
Systems operate is low power supply, more electronic control so equipment life is higher
Changes in process logic becomes easier since logics are changed mostly through software

Principal Industrial Automation MNCs

Siemens • Fuji Electric

Allen Bradley • Toshiba

Messung • TATA Honeywell

Modicon • Omron

Mitsubishi • Fanuc

Asia Automation • Delta

How industrial automation control system Evolved?

Initially automation was achieved through manual control, operators accustomed to control the procedure at every step. Human intervention 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 on this era was achieved through invention of pneumatic controllers at the begining of 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 from the logic was very complex procedure since lots of rework was required to accomplish alternation in logic. So time taken to complete task changes was very high

Hard wired logic control: contactors, relays (for switching), timers and counters (for timing and counting) were utilized 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 task, electronic logic gates were chosen 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.
