PLC也已具备处理脉冲量的能力。PLC有脉冲信号输入点或模块，可接收脉冲量输入（PI)。PLC有脉冲信号输出点或模块，可输出脉冲量

(PO)。有了处理PIPO这两种功能，加上PLC已有数据处理及运算能力，完全可以依NC的原理进行运动控制。

用PLC实现这个控制，其价格比用NC要低得多。而且，它在进行运动控制的同时，还可进行其它控制。再加上PLC各种运动控制模块的开发与应用，以及相关软件的推出及使用，用PLC进行种种运动控制已变得很容易，其编程也可使用NC语言，很简便。

PLC also has the ability to handle pulse volume. The PLC has a pulse signal input point or module, which can receive pulse quantity input (PI). PLC has pulse signal output point or module, can output pulse quantity(PO). With the two functions of processing PIPO, coupled with the existing data processing and computing capabilities of PLC, motion control can be carried out according to the principle of NC.

Using PLC to achieve this control, the price is much lower than using NC. Moreover, it can also carry out other controls while carrying out motion control. Coupled with the development and application of various motion control modules of PLC, as well as the introduction and use of related software, it has become very easy to carry out various motion control with PLC, and its programming can also use NC language, which is very simple.
