A PLC ( Programmable Logic Controller) is a ruggedized computer used for industrial automation. These controllers can automate a specific process. Learn about configuration, programming, implementation, and more.
How does a programmable logic controller work? The CPU is essentially the brain of the PLC and interprets program instructions and executes them. Input/output (I/O) modules deliver signals fromsensorsand switches (i.e., inputs) to the PLC and send signals to control devices like motors, va...
A Programmable Logic Controller, or PLC, is a ruggedized computer used for industrial automation. They can automate a specific process, machine function, or even an entire production line. This article, from our partners at Unitronics, provides an overview of PLCs. How does a PLC work? The ...
So, what is a PLC and why is it so important in the world of automation? What Is a Programmable Logic Controller? Programmable Logic Controllers (PLCs) are industrial computers, with various inputs and outputs, used to control and monitor industrial equipment based on custom programming. PLCs...
How a Programmable Logic Controller Receives the Input Once you’ve set up the PLC, the system is ready to receive inputs from an input device or equipment. When the PLC receives input from a machine orhuman-machine interface (HMI)connected with the input module, the CPU module runs the ...
What is a PLC? PLC stands for programmable logic controller. A PLC is a programmable computing device that is used to manage electromechanical processes, usually in the industrial niche. A PLC is sometimes referred to as an industrial PC, a term that describes a PLC’s main function as a ...
How is a PLC used in automation/logistics? The programmable logic controller uses an industrial communication network that links and connects the system to the different elements of an automated warehouse. PLC can also be equipped with safety devices that guarantee the reliable and safe operation of...
All PLCs (programmable logic controllers) do essentially the same thing; control some machine process.Typical PLC functionsinclude timing, control, and sequencing of such actions as turning motors, pumps or valves on or off. A safety PLC, on the other hand, is a dedicated controller specifically...
Programmable logic controllers or PLCs are rugged, reliable computerized control systems used for automation in industrial applications. PLCs contain a processor, power supply, I/O modules, and communication modules housed in a chassis. Input devices like sensors are monitored by a PLC which then ...
PLC Operation If you are trying to understand a PLC system better, it will be beneficial to learn how a PLC controller operates once the program is written and the appropriate I/O modules are selected. The programmable logic controller will process the given information (inputs), execute the ...
