What does a 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.
Which is an example of PLC programmable logic controller?
Other examples of PLC programming applications that are in use in various industries today include water tank quenching systems in the aerospace sector, filling machine control system in the food industry, – industrial batch washing machine control and closed loop textile shrinkage systems.

How much does a Programmable Logic Controller make?
A Programmable Logic Controller in your area makes on average $62,264 per year, or $1,441 (2%) more than the national average annual salary of $60,823.
Why PLC is used?
A programmable logic controller, PLC, or programmable controller is a digital computer used for automation of typically industrial electromechanical processes, such as control of machinery on factory assembly lines, amusement rides, or light fixtures. PLCs are used in many machines, in many industries.
What are the 4 main components of a PLC?
All Programmable Logic Controllers (PLCs) have four basic components. The four basic components of a Programmable Logic Controller include the power supply, input/output (I/O) section, processor section, and programming section. See Figure 1.
How many types of PLC programming are there?
5 different
The International Electrotechnical Commission 61131-3 outlines 5 different PLC Programming languages: ladder logic, structured text, function block diagrams, sequential function charts, and instruction lists. Each one of these languages has advantages, weaknesses, and best use cases.
How are PLCs programmed?
Modern PLCs can be programmed in a variety of ways, from the relay-derived ladder logic to programming languages such as specially adapted dialects of BASIC and C. Another method is state logic, a very high-level programming language designed to program PLCs based on state transition diagrams.
What is HMI in PLC?
A Human Machine Interface, or HMI for short, is a device that allows a human to give directions and receive feedback from the PLC that is controlling the manufacturing process. In other words, it is a means to input commands into your machines and earn feedback about their status.
What are the 3 types of PLC and Allen Bradley?
There are many three types of PLC you can use, MicroLogix. CompactLogix. ControlLogix.
What is PLC certification?
The Industrial Controls: Programmable Logic Controller (PLC) Certificate of Achievement is a course of study designed to quickly train new learners or incumbent electrical mechanics in the skills necessary to troubleshoot and program the PLCs used in batch and/or discrete automation.
How does a programmable logic controller ( PLC ) work?
A programmable logic controller (PLC) is a special form of microprocessor-based controller that uses a programmable memory to store instructions and to implement functions such as logic, sequencing, timing, counting, and arithmetic to control machines and processes and is designed to be operated by engineers with perhaps a limited knowledge of
Who was the father of the programmable logic controller?
In a parallel development Odo Josef Struger is sometimes known as the “father of the programmable logic controller” as well. He was involved in the invention of the Allen-Bradley programmable logic controller (PLC) during 1958 to 1960.
What is the abbreviation for programmable logic controller?
Lecture – Introduction to PLC’s MME 486 – Fall 2006 4 of 47 Programmable Logic Controller • A programmable logic controller (PLC) is a specialized computer used to control machines and process.
Who is the manufacturer of the PLC controller?
Struger is credited with creating the PLC acronym. Allen-Bradley (now a brand owned by Rockwell Automation ), the manufacturer of the controller, became a major programmable logic controller device manufacturer in the United States during the tenure of Struger.
