一、主機(jī)系統(tǒng)故障
PLC維修時(shí)， 主機(jī)系統(tǒng)最容易發(fā)生故障的地方一般在電源系統(tǒng)和通訊網(wǎng)絡(luò)系統(tǒng)，電源在連續(xù)工作、散熱中，電壓和電流的波動(dòng)沖擊是不可避免的。通訊及網(wǎng)絡(luò)受外部干擾的可能性大，外部環(huán)境是造成通訊外部設(shè)備故障的最大因素之一。 PLC維修時(shí)，系統(tǒng)總線的損壞主要由于現(xiàn)在PLC 多為插件結(jié)構(gòu)，長(zhǎng)期使用插拔模塊會(huì)造成局部印刷板或底板、接插件接口等處的總線損壞，在空氣溫度變化、濕度變化的影響下，總線的塑料老化、印刷線路的老化、接觸點(diǎn)的氧化等都是系統(tǒng)總線損耗的原因。所以在系統(tǒng)設(shè)計(jì)和處理PLC維修系統(tǒng)故障的時(shí)候要考慮到空氣、塵埃、紫外線等因素對(duì)設(shè)備的破壞。目前PLC 的主存儲(chǔ)器大多采用可擦寫ROM，其使用壽命除了主要與制作工藝相關(guān)外，還和底板的供電、CPU 模塊工藝水平有關(guān)。而PLC 的中央處理器目前都采用高性能的處理芯片，故障率已經(jīng)大大下降。PLC維修時(shí)， 主機(jī)系統(tǒng)的故障的預(yù)防及處理主要是提高集中控制室的管理水平，加裝降溫措施，定期除塵，使PLC 的外部環(huán)境符合其安裝運(yùn)行要求;同時(shí)在系統(tǒng)維修時(shí)，嚴(yán)格按照操作規(guī)程進(jìn)行操作，謹(jǐn)防人為的對(duì)主機(jī)系統(tǒng)造成損害。
二、I/O 端口故障
PLC維修時(shí)，PLC 最大的薄弱環(huán)節(jié)在I/O 端口。PLC 的技術(shù)優(yōu)勢(shì)在于其I/O 端口，在主機(jī)系統(tǒng)的技術(shù)水平相差無(wú)幾的情況下，I/O 模塊是體現(xiàn)PLC 性能的關(guān)鍵部件，因此它也是PLC 損壞中的突出環(huán)節(jié)。要減少I/O 模塊的故障就要減少外部各種干擾對(duì)其影響，首先要按照其使用的要求進(jìn)行使用，不可隨意減少其外部保護(hù)設(shè)備，其次分析主要的干擾因素，對(duì)主要干擾源要進(jìn)行隔離或處理。
