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.
What is a PLC 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. Almost any production line, machine function, or process can ...
比较桌上型计算机、PLC由电源、微处理器晶片、RAM记忆输入和输出,然而,可编程序控制器(PLC),COM.与计算机在一些重要的方面如下。他们是设计工作了多年的更极其条件在一个工厂里。他们必须意义上的大量的输入和控制大量的输出毫秒。一个象征性的可编程语言,使它更容易,要了解为什麽特定的输出一定会改变一...
What is a PLC? PLCs are rugged, compact computing devices that are purpose-built for use in control systems. Developed as a replacement for traditional electromechanical components, PLCs are extremely versatile devices that can collect data, execute complex control logic, and send commands to many...
A programmable logic controller (PLC) is a small, modular,solid-statecomputer with customized instructions for performing a particular task. PLCs, used in various industrial control systems (ICSes), have primarily replaced mechanical relays, drum sequencers and cam timers. ...
PLC (Programmable Logic Controller) has many features similar to our personal computer at home. They both have a power supply unit, a CPU (Central Processing Unit), Inputs & Outputs (I/O) ports, RAM and ROM memory, and control software. The biggest difference between the two is PLC can...
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...
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 program and determines the output. Then, the PLC sends...
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.
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...
