，M1=ON、M3=ON情况3修改M1值为OFF状态，M3值为ON状态，发现Y1=ON。以上可以发现执行线圈的双重输出，输出结果以Zui下面的线圈为准。这时为什么呢，我们知道PLC程序指令顺序是按照从上到下，从左到右进行处理的，双线圈无论前面的状态如何都以Zui后的线圈为输出结果。那么怎么改变上面的双线圈输出呢，采用并联的方法来实现：双线圈对策这样M3就不会影响M1的作用了，在写程序时候经常会遇到这种情况尤其是步数较多时，写后面的时候会忽略前面的输出，编译时三菱plc是不会报错的，怎么办，我们在下载程序对程序进行一次检查，点击工具程序检查：程序检查点击执行后会在下面的输出结果报错：程序检查结果这样就检查了双线圈输出避免了不必要的调试。

1长距离的线管尽量用整管。1当布线长度超过15米或中间有3个弯曲时，在中间应该加装一个接线盒。因为拆装电线时，太长或弯曲多了，电线无法从穿线管中穿过去。1配电箱内应设动作电流30mA的漏电保护器，分数路控开，保护断路器。保护断路器的工作电流应与终端电器的Zui大工作电流匹配。1像这种悬空的电路是比较少见的，同样要遵循强、弱电分开。如电话老是有杂音，可能就是弱电受到了强电的干扰。1一般情况下，电线线路要与煤气管道、水管，同一平面≥100mm，不同平面≥50mm空调挂机插座安装离地面需2米以上。
