PLC在数控机床中的工作流程简介 PLC的分类
PLC在数控机床中的工作流程，和通常的PLC工作流程基本上是一致的，分为以下几个步骤:
(1).输入采样:输入采样，就是PLC以顺序扫描的方式读入所有输入端口的信号状态，并将此状态，读入到输入映象寄存器中。当然，在程序运行周期中这些信号状态是不会变化的，除非一个新的扫描周期的到来，并且原来端口信号状态已经改变，读到输入映象寄存器的信号状态才会发生变化。
(2)、程序执行:程序执行阶段系统会对程序进行特定顺序的扫描，并且同时读入输入映像寄存区、输出映像寄存区的读取相关数据，在进行相关运算后，将运算结果存入输出映像寄存区供输出和下次运行使用。
(3)、出刷新阶段:在所指令执行完成后，输出映像寄存区的所有输出继电器的状态(接通/断开)在输出刷新阶段转存到输出锁存器中，通过特定方式输出，驱动外部负载。
