2．设计思路本文提出的4种简易设计方法都是先设计步进阶梯，在步进阶梯实现由转步主令信号控制辅助继电器得失电；然后根据步进阶梯设计输出阶梯，在输出阶梯实现由辅助继电器控制输出继电器得失电。这4种设计法所设计的梯形图电路结构及相应的指令应适用于大多数PLC机型，具有通用性。
由于各种PLC机型的编程元件代号及其编号不尽相同，为便于阐述，本文约定：所有梯形图中的输入继电器、输出继电器、辅助继电器（又称内部继电器）的代号分别为：X、Y、M。设计中所用到的某些功能指令，如置位指令约定为S×，复位指令为R×；移位指指令为SR×。其中的“×”表示编程元件的编号，用十进制数表示。用这些方法设计实际的控制系统时，应将编程元件代号和编号变换成所选用的PLC机型对应的代号和编号。
