故障多发点在阀门或闸板这一类的设备上，因为这类设备的关键执行部位，相对的位移一般较大，或者要经过电气转换等几个步骤才能完成阀门或闸板的位置转换，或者利用电动执行机构推拉阀门或闸板的位置转换，机械、电气、液压等各环节稍有不到位就会产生误差或故障。长期使用缺乏维护，机械、电气失灵是故障产生的主要原因，因此在系统运行时要加强对此类设备的巡检，发现问题及时处理。我厂对此类设备建立了严格的点检制度，经常检查阀门是否变形，执行机构是否灵活可用，控制器是否有效等，很好地保证了整个控制系统的有效性。

故障点可能发生在开关、极限位置、安全保护和现场操作上的一些元件或设备上，其原因可能是因为长期磨损，也可能是长期不用而锈蚀老化。如该生产线窑尾料球储库上的布料行走车来回移动频繁，而且现场粉尘较大，所以接近开关触点出现变形、氧化、粉尘堵塞等从而导致触点接触不好或机构动作不灵敏。对于这类设备故障的处理主要体现在定期维护，使设备时刻处于完好状态。对于限位开关尤其是重型设备上的限位开关除了定期检修外，还要在设计的过程中加入多重的保护措施。

故障点可能发生在PLC系统中的子设备，如接线盒、线端子、螺栓螺母等处。这类故障产生的原因除了设备本身的制作工艺原因外还和安装工艺有关，如有人认为电线和螺钉连接是压的越紧越好，但在二次维修时很容易导致拆卸困难，大力拆卸时容易造成连接件及其附近部件的损害。长期的打火、锈蚀等也是造成故障的原因。根据工程经验，这类故障一般是很难发现和维修的。所以在设备的安装和维修中一定要按照安装要求的安装工艺进行，不留设备隐患。

故障点是传感器和仪表，这类故障在控制系统中一般反映在信号的不正常。这类设备安装时信号线的屏蔽层应单端可靠接地，并尽量与动力电缆分开敷设，特别是高干扰的变频器输出电缆，而且要在PIC内部进行软件滤波。这类故障的发现及处理也和日常点巡检有关，发现问题应及时处理。

故障主要是电源、地线和信号线的噪声(干扰)，问题的解决或改善主要在于工程设计时的经验和日常维护中的观察分析。

要减小故障率，很重要的一点是要重视工厂工艺和安全操作规程，在日常的工作中要遵守工艺和安全操作规程，严格执行—些相关的规定，如保持集中控制室的环境等等，同时在生产中也要加强这些方面的霄理。

过程控制系统本身是一个完整的系统，所以在分析故障或处理故障时也要注意系统性，单独的对某一部分的优化有时并不能提高系统的整体性能。如过分追求元器件的精度而不考虑实际的需要以及和相关设备精度的匹配，将徒然增加系统成本。在日常维护中也有过把系统越改越复杂的现象，如采用复杂的控制方式和设备来实现本可以用简单装置来实现的控制，违背了经济、简单、实用的原则，并可能会增加故障率，这也是要注意的地方。

随着工业设备自动化控制技术的发展，可编程控制器(PLC)在工业设备控制中的应用越来越广泛。PLC控制系统的可靠性直接影响到企业的安全生产和经济运行，系统的抗干扰能力是关系到整个系统可靠运行的关键。本文详细介绍了影响PLC运行的干扰类型及来源，并提出抗干扰设计的实施策略。

自动化系统所使用的各种类型PLC中，有的是集中安装在控制室，有的是安装在生产现场和各电机设备上，它们大多处在强电电路和强电设备所形成的恶劣电磁环境中。要提高PLC控制系统可靠性，一方面要求PLC生产厂家提高设备的抗干扰能力，另一方面要求应用部门在工程设计、安装施工和使用维护中引起高度重视，多方配合才能完善解决问题，有效地增强系统的抗干扰性能。
