PLC的各种功能主要是通过运行控制程序来实现。编制程序时，需要合理使用PLC提供的编程元件（即软元件）。FPO型PLC中常用的编程元件有两种：位元件（bit）和字元件（word）。位元件实际上是PLC内存区域所提供的一个二进制位单元，又被称为软继电器，主要用作基本顺序指令的编程元件，如输入继电器Xn、输出继电器Yn、内部通用继电器Rn、定时（计数）器等，其参与控制的方式主要是通过对应触点的通断状态改变影响逻辑运算结果即输出。
字元件则为PLC内存区域内的一个字单元（16bit），主要用作功能指令和高级指令的编程元件，通常用以存放数据，如数据寄存器DTn，定时(计数)器的设定值SVn、经过值EVn等。字元件没有触点，通常以整体内容参与控制。
值得注意的是内存中的输入（X）区、输出（Y）区和内部通用（R）区，该区中的每个bit均可用作位元件，而且每16bit可构成一个字元件，如WRIO即是由16个位元件R100～R10F构成的字元件，该字元件中的内容一旦发生变化，这16个位的状态也随之发生改变。
