按功能分类
根据PLC的功能不同，可将PLC分为低档、中档、。
（1）低档PLC
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、数据传送和比较及通信等功能，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
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、子程序及通信联网等功能；有些还可增设中断控制、PID控制等功能，适用于复杂的控制系统。
（3）PLC
PLC除具有中档PLC的功能外，还增加了带符号算术运算、矩阵运算、位逻辑运算、平方根运算及其他特殊功能函数的运算、制表及表格传送功能等。PLC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，进而实现工厂自动化。
