JAMSC-C8120

输入模块一般由光电耦合电路组成；输出模块根据型号不同有继电输出、晶体管输出、光电输出等。每一点输入输出都有相应的发光二极管指示。有输入信号但该点不亮或确定有输出但输出灯不亮时就应该怀疑I/O模块有故障。输入和输出模块有6到24个点，如果只是因为一个点的损坏就更换整个模块在经济上不合算。通常的做法是找备用点替代，然后在程序中更改相应的地址。但要注意，程序较大是查找具体地址有困难。特别强调的是，无论是更换输入模块还是更换输出模块，都要在PLC断电的情况下进行，S5带电插拔模块是绝对不允许的。

在PLC控制系统中出现的故障率为：CPU及存储器占5%，I/O模块占15%，传感器及开关占45%，执行器占30%，接线等其他方面占5%，可见80%以上的故障出现在外围线路。外围线路由现场输入信号（如按钮开关、选择开关、接近开关及一些传感器输出的开关量、继电器输出触点或模数转换器转换的模拟量等）和现场输出信号（电磁阀、继电器、接触器、电机等），以及导线和接线端子等组成。接线松动、元器件损坏、机械故障、干扰等均可引起外围电路故障，排查时要仔细，替换的元器件要选用性能可靠安全系数高的优质器件。一些功能强大的控制系统采用故障代码表表示故障，对故障的分析排除带来极大便利，应好好利用。

总结：西门子PLC其他系列的故障判断和处理方法与此原理相同可依次类推。上海彩亚电路板维修有限公司提醒：任何芯片级精密设备遇到故障时，在没有十足把握情况下，一定要请专业的技术服务企业予以处理，擅自改动程序和维修紧密设备电路板可能会造成设备维修难度加大甚至报废的严重后果。
