LG PLC中基于MOV指令实现步进顺序控制的方法

The Technique to Achieve Sequential Control Based on MOV Instructions in LG PLC

步进阶梯指令是PLC中常用的一种顺序控制指令,它能够方便简单地实现顺序控制,但不同的PLC中步进阶梯指令又有其不同的特点。针对这些特点,分析了LGPLC步进阶梯指令的局限性,并介绍了利用MOV指令实现步进控制的方法。

Step ladder instruction is a commonly instruction used to sequential control in the PLC, it can facilitate the realization of sequence control, but the different step ladder instruction has its different characteristics. The limitation of the LG PLC step ladder instruction was analyzed, and the use of MOV instructions to achieve sequential control was described.
