P0917HB FBM221 备件

经验设计法一般适合于设计一些简单的梯形图程序或复杂系统的某一局部程序（如手动程序等）。如果用来设计复杂系统梯形图，存在以下问题：

   1)．考虑不周、设计麻烦、设计周期长

  用经验设计法设计复杂系统的梯形图程序时，要用大量的中间元件来完成记忆、联锁、互锁等功能，由于需要考虑的因素很多，它们往往又交织在一起，分析起来非常困难，并且很容易遗漏一些问题。修改某一局部程序时，很可能会对系统其它部分程序产生意想不到的影响，往往花了很长时间，还得不到一个满意的结果。

  2)．梯形图的可读性差、系统维护困难

用经验设计法设计的梯形图是按设计者的经验和习惯的思路进行设计。因此，即使是设计者的同行，要分析这种程序也非常困难，更不用说维修人员了，这给PLC系统的维护和改进带来许多困难。
逻辑设计法
在进行程序设计时以布尔逻辑代数为理论基础，既以逻辑变量“0”或“1”作为研究对象，以“与”、“或”、“非”三种基本逻辑运算为分析依据，对电气控制线路进行逻辑运算，把触点的“通、断”状态用逻辑变量“0”或“1”来表示具有多变量的“与”逻辑关系表达式可以直接转化为触点串连的梯形图。如图2(a)所示。
具有多变量的“或”逻辑关系表达式可以直接转化为触点并联的梯形图。如图2(b)所示。
具有多变量“与或”、“或与”逻辑关系表达式可以直接转化为触点串并联的梯形图。
