| 摘 要： | 通过实例介绍了使用通用逻辑指令PLC程序设计的顺序控制设计法,这种方法适用于所有型号的PLC。其思路是:用辅助继电器来代表"步",某一步为活动步时,对应的辅助继电器为1,当转换条件实现时,该转换的后续步置位变为活动步,将前级步复位变为不活动步。

| Abstract: | The method in sequence control design by universal logic PLC programming instruction is introduced by instances. This method is applicable to all types of PLC. The idea is that the ＂step＂is represented by auxiliary relay,which is going to be 1 when is step is active step. When the transition condition is realized,its post-step is going to be active step,the pre-step is reset to be a inactive step. |
