- 1. A PRESENTATION ONA PRESENTATION ON AUTOMATIONAUTOMATION ( PLC- SCADA )( PLC- SCADA ) Submitted by- Saifullah Akhtar Zuber khan Submitted to – Rahul makkar sir (Department of ECE)
- 2. What is Automation ?What is Automation ? Automation is basically the delegation of human control function to technical equipment for •Increasing Productivity • Increasing Quality • Reducing Cost • Increasing Safety in working conditions
- 3. Industrial AutomationIndustrial Automation Automation is encompassing virtually every walk of life. Automation solutions are required right from agricultural to space technology. Plant Automation is the necessity for the manufacturing industry to survive in today’s globally competitive market
- 4. Productivity Quality Labour Cost Plant Total Automation Manufacturing Competitiveness Solution Why Automation required in Industry
- 5. History of AutomationHistory of Automation Pneumatic Control Hard wired logic Control Electronic Control using Logic Gates Programmable Logic Controller Manual Control
- 6. Manual ControlManual Control All the actions related to process control are taken by the operators Drawbacks Likely human errors and consequently its effect on quality of final product The production, safety, energy consumption and usage of raw material are all subject to the correctness and accuracy of human action.
- 7. Pneumatic ControlPneumatic Control Industrial automation, with its machine and process control, had its origin in the 1920s with the advent of "Pneumatic Controllers". Actions were controlled by a simple manipulation of pneumatic valves, which in turn were controlled by relays and switches. Drawbacks • Bulky and Complex System • Involves lot of rework to implement control logic • Longer project time
- 8. Hard wired logic controlHard wired logic control The contactor and Relays together with hardware timers and counters were used in achieving the desired level of automation Drawbacks • Bulky panels • Complex wiring • Longer project time • Difficult maintenance and troubleshooting
- 9. Electronic Control using Logic GatesElectronic Control using Logic Gates In 1960s with the advent of electronics, the logic gates started replacing the relays and auxiliary contactors in the control circuits. The hardware timers & counters were replaced by electronic timers Advantages Drawbacks •Reduced space requirements •Energy saving •Less maintenance & greater reliability •Changes in control logic not possible •More project time
- 10. Programmable Logic ControllersProgrammable Logic Controllers In 1970s with the coming of microprocessors and associated peripheral chips, the whole process of control and automation underwent a radical change. Instead of achieving the desired control or automation through physical wiring of control devices, in PLC it is achieved through a program or say software. The programmable controllers have in recent years experienced an unprecedented growth as universal element in Industrial Automation. It can be effectively used in applications ranging from simple control like replacing small number of relays to complex automation problems
