用在PLC系统和设备之间提供连接的电线被称为软接线。例如,假设一个按钮应该是控制一个电机的运行。在传统的控制系统中,按钮将直接连接到电机。然而,在PLC系统,无论是按钮和电机都连接到PLC。然后,PLC控制程序会完成两者间的互连,实现按钮控制电机。 可编程控制器在60年代末首次在美国出现,当时称为可编程逻辑控制器...

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 a computer that fulfils a basic function: managing and controlling the automated warehouse equipment in real time.
is placed in run mode it will execute the program and operate the process. Input data from connected field devices (e.g., switches, sensors, etc.) is processed, and then the CPU “executes” or performs the control program that has been stored in its memory system. Since a PLC is a ...
Here in this article, we will learn about What is PLC and how Arduino can be used as PLC. Introduction to PLC (Programmable Logic Controller) First, let us understand the term Industrial Automation before going for PLC. As we all know using machines for work in industries is more cost-...
The most common type of PLC is the fixed PLC. Fixed PLCs are smaller and more affordable than modular PLCs, which makes fixed PLCs a good choice for smaller or portable control systems or for performing standalone tasks. However, fixed PLCs are made with the processing unit, terminals, ...
