plc的工作方式PLC是一种由程序控制运行的设备，其工作方式与微型计算机不同，微型计算机运行到结束指令END时，程序运行结束。PLC运行程序时会按顺序依次逐条执行存储器中的程序指令，当执行完后的指令后，并不会马上停止，而是又重新开始再次执行存储器中的程序，如此周而复始，PLC的这种工作方式称为循环扫描方式。PLC的工作过程如下图所示：PLC的工作过程PLC通电后，首先进行系统初始化，将内部电路恢复到起始状态，然后进行自我诊断，检测内部电路是否正常，以确保系统能正常运行，诊断结束后对通信接口进行扫描，若接有外设则与其通信。

串联接线这种接线应用广，也普遍，因为布线方便。但是问题来了，接线的时候是把两线破皮后插入接线柱再拧紧螺丝还是把两线铰接在一起插入接线柱再拧紧螺丝？看起来都接上了，但是效果却差别很大。1，如果电工师傅按前者的方式接线，没有把导线铰接在一起。一个插座坏掉了。接线柱位置有可能烧坏，两根导线分离，后面串的插座全部断电。2，铰接到一起的，涮锡后插入，这样即使接线柱烧坏，两根导线还是连在一起，不影响后面的插座。
