What is industrial Automation
Industrial Automation is often a technique by which we make hand over human control to machines. In https://idealprocessandautomation.com.au/ are designed to accomplish the tasks which people utilized to achieve. Why it is done? Because of its advantages:
Through Industrial automation we're able to do mass production with less manpower
Quality of the method is increased
Safety of person & devices are increased
More accurate process control
Since human intervention is less so reliability of the system is higher
Systems operate is low power, more electronic control so equipment our life is higher
Changes in process logic becomes easier since logics are changed mostly through software
Principal Industrial Automation MNCs
L & T • ALSTOM
Schneider • FESTO
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 process at each and every step. Human intervention was there at every step. Drawbacks were substandard quality output, errors linked to human involvement affected compromised safety, wastage of raw material, and accuracy of human action.
Then came Pneumatic Control: Industrial automation within this era was achieved through invention of pneumatic controllers in early 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 in the logic was very complex procedure since lots of rework was forced to accomplish alternation 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 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 chosen 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 usage of electronics space and requirements reduced, maintenance requirement reduced & systems were more reliable.
