- 3. Introduction of automation Automation is any sensing, detection, information-processing, decision-making, or control action that could be performed by humans but is actually performed by a machine. Automation is the use of control systems and information technologies to reduce the need for human work in the production of goods and services. In the scope of industrialization, automation is a step beyond mechanization
- 4. Advantage of automation • Increased throughput or productivity. • Improving operating efficiencies. • Improved quality. • Increase consistency of output. • Reduced direct human labour costs and expenses. • Providing outstanding customer service.
- 5. VFD • A Variable Frequency Drive (VFD) is a type of motor controller that drives an electric motor by varying the frequency and voltage supplied to the electric motor. • Other names for a VFD are variable speed drive, adjustable speed drive, adjustable frequency drive, AC drive, microdrive, and inverter. • VFDs are used in applications ranging from small appliances to the largest of mine mill drives and compressors.
- 7. Working of VFD • The first stage of a Variable Frequency AC Drive, or VFD, is the Converter. • The VFD dc bus has a dc voltage with an AC ripple. We can get rid of the AC ripple on the DC bus by adding a capacitor. • Now the inverter converts the DC back to AC of required frequency.
- 8. Advantages of VFD • VFDs allow you to match the speed of the motor-driven equipment to the load requirement. • By operating motors at the most efficient speed for your application, fewer mistakes will occur, and production levels will increase. • equipment will last longer and will have less downtime due to maintenance when it’s controlled by VFDs

- 12. PLC A PLC (i.e. Programmable Logic Controller) is a device that was invented to replace the necessary sequential relay circuits for machine control. The PLC works by looking at its inputs and depending upon their state, turning on/off its outputs. The user enters a program, usually via software, that gives the desired results. PLCs are used in many "real world" applications. Almost any application that needs some type of electrical control has a need for a PLC.

- 15. 15 Major Components of a Common PLC POWER SUPPLY Provides the voltage needed to run the primary PLC components I/O MODULES Provides signal conversion and isolation between the internal logic- level signals inside the PLC and the field’s high level signal.
- 16. 16 Major Components of a Common PLC PROCESSOR Provides intelligence to command and govern the activities of the entire PLC systems. PROGRAMMING DEVICE used to enter the desired program that will determine the sequence of operation and control of process equipment or driven machine.
- 17. Advantages of PLC: Less wiring. Wiring between devices and relay contacts are done in the PLC program. Easier and faster to make changes. Trouble shooting aids make programming easier and reduce downtime. Reliable components make these likely to operate for years before failure. 17

- 19. SCADA SCADA stands for “Supervisory Control and Data Acquisition”. Purely Software Package that is positioned on top of hardware. SCADA refers to a system that collects data from various sensors at a factory, plant or in other remote locations and then sends this data to a central computer which then manages and controls the data. SCADA focuses on gathering and circulating the right amount of system information to the right person or computer within the right amount of time.
