目前，PLC在国内外已广泛应用于钢铁、石油、化工、电力、建材、机械制造、汽车、轻纺、交通运输、环保及文化娱乐等各个行业，随着其性能价格比的不断提高，应用的范围还在不断扩大，PLC的应用大致可归纳为以下几类。
1)、开关量的逻辑控制
这是PLCzui基本、zui广泛的应用领域。PLC的逻辑控制取代传统的继电系统控制电路，实现逻辑控制、顺序控制，既可用于单机控制，也可用于多机群控及自动化生产线的控制等。如机床电气控制、装配生产线、电梯控制、冶金系统的高炉上料系统以及各种生产线的控制。
2)、运动控制
PLC可以用于圆周运动或直线运动的控制。目前，大多数的PLC制造商都提供拖动步进电机或伺服电机的单轴或多轴位置控制模块，这一功能可广泛用于各种机械，如金属切削机床、金属成型机床、机器人、电梯等。
3)、过程控制
过程控制是指对温度、压力、流量、速度等连续变化的模拟量的闭环控制。PLC采用相应的A/D和D/A转换模块及各种各样的控制算法程序来处理模拟量，完成闭环控制。PID调节是一般闭环控制系统中用得较多的一种调节方法。过程控制在冶金、化工、热处理、锅炉控制等场合有非常广泛的应用。现代的大、中型PLC一般都有闭环PID控制模块，这一功能可以用PID子程序来实现，而更多的是使用PID模块来实现。

4)、数据处理
PLC具有数学运算（含矩阵运算、函数运算、逻辑运算）、数据传送、数据转换、排序、查表、位操作等功能，可以完成数据的采集、分析及处理。这些数据可以通过通信接口传送到的智能装置进行处理，或将它们打印备用。数据处理一般用于大型控制系统，如造纸、冶金、食品工业中的一些大型控制系统。
5）、通信及联网
PLC通信括PLC相互之间、PLC与上位机、PLC与其它智能设备间的通信。PLC与其它智能控制设备一起，可以构成“集中管理、分散控制"的分布式控制系统，满足工厂自动化系统发展的需要。
● PLC控制系统与继电器控制系统的区别 ：
⑴ 组成器件不同：继电器控制线路是许多真正的硬件继电器组成，而梯形图则由许多所谓“软继电器"组成。
⑵ 触点数量不同：硬继电器的触点数量有限，用于控制的继电器的触 点数一般只有4～8对；而梯形图中每个“软继电器"供编程使用的触点数有无限对。
⑶ 实施控制的方法不同：在继电器控制线路中，实现某种控制是通过各种继电器之间硬接线解决的。而PLC控制是通过梯形图即软件编 程解决的。
⑷ 工作方式不同：在继电器控制线路中，采用并行工作方式；而在梯形图的控制线路中，采用串行工作方式。BENTLY NEVADA 3300/35-04-02-02-00-00 SIX CHANNEL TEMPERATURE MONITOR NEW NO BOX
