可编程逻辑控制器或 PLC 在当今的各种流程和制造行业中无处不在。PLC 最初旨在取代机电继电器系统，以便为修改控制系统的操作提供更简单的解决方案。无需重新连接大量继电器，只需从 PC 或编程设备快速下载，即可在几秒钟内更改控制逻辑。

PLC 是一种工业级数字计算机，旨在执行控制功能，尤其适用于工业应用。

今天的大多数 PLC 都是模块化的，允许用户添加各种功能，包括离散和模拟输入和输出、PID 控制、位置控制、电机控制、串行通信和高速网络。与继电器组等较旧的技术相比，PLC 更易于故障排除和维护、更可靠、更具成本效益且用途更广泛。

Programmable logic controllers, or PLCS, are ubiquitous in a variety of processes and manufacturing industries today. PLCS were originally designed to replace electromechanical relay systems in order to provide a simpler solution for modifying the operation of control systems. Instead of reconnecting a large number of relays, you can quickly download them from a PC or programming device and change the control logic in seconds.

A PLC is an industrial-grade digital computer designed to perform control functions and is particularly suitable for industrial applications.

Most PLCS today are modular, allowing users to add a variety of functions, including discrete and analog inputs and outputs, PID control, position control, motor control, serial communication, and high-speed networking. PLCS are easier to troubleshoot and maintain, more reliable, more cost-effective, and more versatile than older technologies such as relay groups.
