分析原有系统的工作原理
了解被控设备的工艺过程和机械的动作情况，根据继电器电路图分析和掌握控制系统的工作原理。
2．PLC的I/O分配
确定系统的输入设备和输出设备，进行PLC的I/O分配，画出PLC外部接线图。
3．建立其它元器件的对应关系
确定继电器电路图中的中间继电器、时间继电器等各器件与PLC中的辅助继电器和定时器的对应关系。
以上（2）和（3）两步建立了继电器电路图中所有的元器件与PLC内部编程元件的对应关系，对于移植设计法而言，这非常重要。在这过程中应该处理好以几个问题：
1）继电器电路中的执行元件应与PLC的输出继电器对应，如交直流接触器、电磁阀、电磁铁、指示灯等；
2）继电器电路中的主令电器应与PLC的输入继电器对应，如按钮、位置开关、选择开关等。热继电器的触点可作为PLC的输入，也可接在PLC外部电路中，主要是看PLC的输入点是否富裕。注意处理好PLC内、外触点的常开和常闭的关系。
