在PLC设计的时候，多是出于自己对电气控制的电路设计而转换过来的，但是这两个方面都还上有点区别，所以在很多时候都面对一个题目都要看很久，这让我想起了一种方法。

对于一个问题总是有它的多面性，也就是说什么问题都能给它化整为零，把它的要求一步步的展开，一个一个的进行设计，然后再对把一个一个的合拢，然后在对全局进行考虑，这样就避免了思维的错乱。这个看起来有点像在顺序控制的时候用功能图去表示了，其实不是的，这个就像砌房子，把一块块砖头砌上去，再整合就达到了目的，我觉得比那个好理解些。

在一个问题的设计时我是这样子看的，首先看看它要什么要求，然后再把它的要求分为几个块，再针对每个块又分成几个块。最后就是针对每个小块编程，最后把程序稍做修改就达到了目的，最后在PLC上检查并简化程序。

设计可编程控制器时，安全性是第一重要的，即即使在外部的电源发生异常时，可编程控制器出现故障时，整个系统也能在安全状态下工作，请务必在可编程控制器外部，设置安全电路，误操作，误输出是产生事故的原因。

1。务必在可编程控制器外部，设置如下几种电路，

紧急停止电路，保护电路，正转逆转等相反操作的连锁电路，定位的上限/下线等防止损坏的连锁电路。

2.可编程控制器CPU有监视定时器等自检功能

可编程控制器CPU以监视定时器等自检功能，检测出异常时，输出全部关闭，担当可编程控制器的CPU检测不出输入输出控制部分的异常时就不能控制输出，这时，为使机器在安全状态下运行，请设计外电路及机构

3.设计确保传感器的后备电源产生过负荷时的安全：

传感器的后备电源产生过负荷时，电压自动下降，除可编程控制器输入不工作之外，全部输出都关闭，这时，请设计外电路和机构，以使其在安全状况下工作。

4.设计确保当有与重大故障有联系的输出信号时机器的安全：

因输出继电器，晶体管的故障，输出时而为ON,时而为OFF的现象出现，当有与重大故障有联系的输出信号时，请设计外电路和机构，以使机器在安全状况下运行.
