为了使顺序控制系统工作可靠，通常采用步进式顺序控制电路结构。所谓步进式顺序控制，是指控制系统的任一程序步（以下简称步）的得电必须以前一步的得电并且本步的转步主令信号已发出为条件。对生产机械而言，受控设备任一步的机械动作是否执行，取决于控制系统前一步是否已有输出信号及其受控机械动作是否已完成。若前一步的动作未完成，则后一步的动作无法执行。这种控制系统的互锁严密，即便转步主令信号元件失灵或出现误操作，亦不会导致动作顺序错乱。

          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。
