西门子PLC在工业自动化领域用途广泛，当西门子PLC出现故障怎么办？西门子PLC系统故障维修，由于PLC机型不同，另外。1/0与LED连接方式的不一样(有的接于1/0单元接口上，有的接于1/0单元上)所以，根据LED判断的故障范围也有差别。

 1、不执行程序：　　6FC5210-0DA00-1AA1  伺服备件　　一般情况下可依照输入---顺序执行---输出的方法进行检查，或用写入器构成的输入监视器检查。当输入LED不亮时，1输入检查是利用输入LED指示灯识别。可初步确定是外部输入系统故障，再配合万用表检查。如果输出电压不正常，就可确定是输入单元故障。当LED亮而内部监视器无显示时，则可认为是输入单元、CPU单元或扩展单元的故障。　　
　　则是顺序错误(例如内部继电器双重使用等),2顺序执行检查是通过写入器上的监视器检查。当梯形图的接点状态与结果不一致时。或是运算局部出现故障。　　
　　则可认为是CPU单元、1/0接口单元的故障。当输出LED亮的而无输出，3输出检查可用输出LED指示灯识别。当运算结果正确而输出LED指示错误时。则可判断是输出单元故障，或是外部负载系统呈现了故障。6FC5210-0DA00-1AA1  伺服备件6SY7000-0AC216SY7000-0AC226SY7000-0AC236SY7000-0AC246SY7000-0AC256SY7000-0AC276SY7000-0AC336SY7000-0AC346SY7000-0AC356SY7000-0AC366SY7000-0AC376SY7000-0AC386SY7000-0AC416SY7000-0AC426SY7000-0AC486SY7000-0AC506SY7000-0AC606SY7000-0AC646SY7000-0AC666SY7000-0AC676SY7000-0AC686SY7000-0AC706SY7000-0AC716SY7000-0AC756SY7000-0AC776SY7000-0AC786SY7000-0AC806SY7000-0AD016SY7000-0AD026SY7000-0AD046SY7000-0AD056SY7000-0AD076SY7000-0AD086SY7000-0AD106SY7000-0AD116SY7000-0AD126SY7000-0AD136SY7000-0AD146SY7000-0AD186SY7000-0AD216SY7000-0AD236SY7000-0AD336SY7000-0AD346SY7000-0AD356SY7000-0AD366SY7000-0AD376SY7000-0AD456SY7000-0AD506SY7000-0AD516SY7000-0AD526SY7000-0AD536SY7000-0AD546SY7000-0AD556SY7000-0AD566SY7000-0AD576SY7000-0AD726SY7000-0AD756SY7000-0AD826SY7000-0AD846SY7000-0AD856SY7000-0AD866SY7000-0AD876SY7000-0AD886SY7000-0AE006SY7000-0AE016SY7000-0AE026SY7000-0AE036SY7000-0AE046SY7000-0AE056SY7000-0AE066SY7000-0AE076SY7000-0AE086SY7000-0AE106SY7000-0AE116SY7000-0AE126SY7000-0AE136SY7000-0AE146SY7000-0AE15
