（二）PLC 控制系统故障的微观诊断
1、电源故障
PLC 较容易发生故障的地方一般在电源系统和系统总线。电源在连续工作中，电压和电流的波动冲击是不可避免的。PLC 的电源输入前端应加隔离变压器，某些场合，可同时采用加隔离变压器和低通滤波器的方法，来自电网的干扰与冲击。变压器二次连接线应采用双绞线，同时加装降温措施，并定期除尘。系统总线的损坏主要出现在模块式PLC 上。模块式PLC 多为插件结构，经常插拔模块会造成局部印刷板或底板、接插件接口等处的总线损坏。在环境温度、湿度的影响下，总线印刷线路的老化、接触点的氧化等都是系统总线损坏的原因。所以在系统设计和处理系统故障时，要考虑到空气、尘埃、腐蚀等因素对设备的破坏。外界环境干扰也是造成PLC 系统故障的重要原因，因此电源、传感器、仪表等布线应尽量与动力电缆分开敷设， 特别要远离高干扰的变频器输出电缆，并将PLC 规范接地。如果硬件上不能干扰，也可以借助软件编程，如利用PLC 软元件里的定时器、计数器、辅助继电器等。
