根据PLC所具有的功能不同，可将PLC分为低档、中档、高档三类。
（1）低档PLC 具有逻辑运算、定时、计数、移位以及自诊断、监控等基本功能，还可有少量模拟量输入输出、算术运算、数据传送和比较、通信等功能。主要用于逻辑控制、顺序控制或少量模拟量控制的单机控制系统。
（2）中档PLC 除具有低档PLC的功能外，还具有较强的模拟量输入输出、算术运算、数据传送和比较、数制转换、远程I/O、子程序、通信联网等功能。有些还可增设中断控制、PID控制等功能，适用于复杂控制系统。
（3）高档PLC 除具有中档机的功能外，还增加了带符号算术运算、矩阵运算、位逻辑运算、平方根运算及其它特殊功能函数的运算、制表及表格传送功能等。高档PLC机具有更强的通信联网功能，可用于大规模过程控制或构成分布式网络控制系统，实现工厂自动化。
