A PLC is an industrial computer that performs discrete or sequential logic functions in a factory environment to control machines and processes. It was originally developed to replace mechanical relays, timers, and counters. PLCs are used successfully to execute complicated control operations in various industries like mining, oil and gas, glass, paper, cement manufacturing, and car manufacturing. PLCs offer advantages like reliability, flexibility, cost effectiveness, high speed, ease of maintenance, and ability to communicate with other computer systems. Their disadvantages include being proprietary, limited design options, and fixed control operations.

PLC
A PLC is a specialized computer used to monitor industrial processes and control machinery. It can be programmed using ladder logic to read input signals from sensors and control outputs to actuators. A PLC system includes an input module to read sensors, an output module to control actuators, a power supply, and a CPU module containing a processor and memory. PLCs offer advantages over relay-based control systems like larger numbers of inputs/outputs, lower cost, easier programming and troubleshooting, and reliability. Common instructions include examine if closed/open to check inputs, and output energize/latch/unlatch to control outputs. Timers allow timing functions like delays and pulse widths to be programmed.

India has many no of renewable energy resources. In that Biomass Gasifier plays a major role as an alternate energy
source. But it facing lot of practical problems on operation due to shortage of manpower and also several problems may
happen in these gasifiers. To overcome the above problems we go for automatic control systems in this gasifier. Therefore we
can neglect the human efforts, errors and operators of the gasifier won’t get affected by the out coming gases from the
gasifiers due to this automation. The gasifier itself works according to the program which we have given. Automation is done
in the miscellaneous function, fuel feeding system and all biomass gasifier control system by using PLC (Programmable Logic
Controller). And then we develop the ladder logic program for sequence of operation in gasifier control system. In this system
the ladder logic function is programmed by using INDRALOGIC software and the hardware component of PLC is Rexroth
Bosch product.

Hello Friends,
in this video i have Discuss PLC Fundamental Wirnig and also we learn Sink and Source.
Part 5 PLC inputs & outputs
There are two main types of input/output modules for a PLC: analog and digital. Analog modules handle continuous signals like 0-10V, 4-20mA, and -20-20mA, while digital modules handle on/off signals represented as 1s and 0s. Common digital inputs include push buttons, switches, and sensors, while common digital outputs include relays, contactors, and lamps. Analog inputs include temperature and pressure sensors, and analog outputs control actuators, valves, and drives. The next video will discuss PLC programming languages.
Part 6 PLC languges.
PLC programming languages include ladder diagram (LD), structured text (ST), sequential function chart (SFC), function block diagram (FBD), and instruction list (IL). Ladder diagram is the simplest form of PLC programming and represents relay logic using rungs and rails. Function block diagram uses blocks to represent program instructions that take inputs on the left and output values on the right. The document also discusses an example of ladder logic using two pushbuttons to control a lamp and describes function block diagrams as representing the relationship between input and output states.
Part 4 Types of PLC
There are two main types of programmable logic controllers (PLCs): modular and compact. Modular PLCs allow expansion through modules, permitting input/output components to be increased flexibly. Compact PLCs have a fixed number of input/output modules within a single case and cannot expand. PLCs are also classified by their output type as relay, transistor, or triac output models.
Part 1 History Of PLC.
The document discusses the history of programmable logic controllers (PLCs). Before PLCs, relay controllers were used for industrial control systems but lacked flexibility. PLCs were first introduced in the late 1960s as a replacement for relay-based systems and offered more programmability. The first commercially successful PLC was developed by Modicon for General Motors, providing more flexibility than relay controllers. The next topic will cover what a PLC is.

Part 2 What is PLC ?
- 1. What is a PLC ?
- 2. Why PLC Use ? PLC Motor OUTPUT PUSH BUTTON INPUT A PLC is a solid state/Computerized industrial computer that performs discrete( 0 , 1 ) or sequential logic in a factory environment its called PLC PLC:- Programmable Logic control
- 3. What Is PLC.. What is Sequential:- it means when you press a switch then start light one by one. What is Discrete:- It means when you press a switch then start all light. It was originally developed to replace mechanical relay,Timer,Counters.PLC are used successfully to execute complicated control operations in a plant.
- 4. Application Process Automation Plants (e.g. mining, oil &gas)
- 8. Application In boilers – Thermal Power Plants
- 9. Car Manufacturing Plants..
- 10. Advantages Reliability Flexibility in programming and reprogramming Cost effective for controlling complex systems. Small Physical size, shorter project time. High Speed of operation. Ability to communicate With computer systems in the plant. Ease of maintenance / troubleshooting. Reduced space. Energy Saving
- 11. Disadvantages PLC device are proprietor it means that part or software of one manufacturer can't be used in combination with parts of another manufacturer. Limited design and cost option. Fixed Circuit operations. PLCs manufacturers offer only closed architectures.
