1.开关量的逻辑控制

开关量的开环控制是PLC的最基本控制功能。PLC的指令系统具有强大的逻辑运算能力，很容易实现定时、计数、顺序(步进)等各种逻辑控制方式。大部分PLC就是用来取代传统的继电接触器控制系统。

⒉数字量控制

控制系统具有旋转编码器和脉冲伺服装置(如步进电机)时，可利用PLC实现接收和输出高速脉冲的功能，实现数字量控制，较为先进的PLC还专门开发了数字控制模块，可实现曲线插补功能，近来又推出了新型运动单元模块，还能提供数字量控制技术的编程语言，使PLC实现数字量控制更加简单。

1. Logic control of switching quantity

The open-loop control of switching quantity is the most basic control function of PLC. PLC instruction system has a powerful logic operation ability, it is easy to achieve timing, counting, sequence (step) and other logic control methods. Most PLCS are used to replace traditional relay contactor control systems.

⒉ Digital quantity control

When the control system has a rotary encoder and pulse servo device (such as stepper motor), the PLC can be used to receive and output high-speed pulse functions to achieve digital quantity control, the more advanced PLC has also specially developed a digital control module, which can realize the curve interpolation function, and recently launched a new motion unit module, which can also provide digital quantity control technology programming language, Make PLC to achieve digital quantity control more simple.
