What are the advantages of programmable logic controllers?
- many inputs and outputs, excellent for controlling and monitoring many processes.
- designed for industrial environments, very robust and reliable.
- ideally suited to supervisory control.
- easy to set up and good for FMS environment.
What does programmable logic controller do?
A PROGRAMMABLE LOGIC CONTROLLER (PLC) is an industrial computer control system that continuously monitors the state of input devices and makes decisions based upon a custom program to control the state of output devices.
What is the most important components of PLC?
Processor which is also called the CPU which means central processing unit. It is the most important component of a PLC. Similarly, processor is the core component in PC. Without a processor a PLC cannot perform its action.
How much does a Programmable Logic Controller make?

What is the application of PLC in daily life?
PLCs are widely used in machines. Examples are processing unit, conveyor belt units, automation units. They are also used in control panels, system panels…Etc. Also used on experimental/temporary traffic lights, lifts, lighting systems, monitoring systems …etc.
What are the advantages of programmable logic controller ( PLC )?
There are some advantages of programmable logic controller (PLC) are given below, It has very faster scan time. It has capable to communication with computer in plant. It has great computational capabilities. It has shorter training time required.
Who was the inventor of the programmable logic controller?
The invention of the programmable logic controller is attributed to Richard Morley and his company, Bedford and Associates. Richard and his team focused on ensuring maintenance electricians and plant engineers could easily understand and use this new programmable controller.
Why is ladder logic easy to program in plc?
Because of its visual layout it is easy to read and program. Ladder logic is a program written in symbols that translate opening and closing relays, timers, shift registers, counters, and mathematical operations. The written symbols deliver the user’s program to the PLC system.
What kind of computer is a PLC used for?
PLC is one kind of electronic device, which is mostly used in the industry and factory for the purpose of controlling the machine. It is an industrial solid-state computer that checks inputs and outputs device, and make decisions based on logics for automated processes or machines.
