PLC控制系統(tǒng)可靠性的管理
5.1人的管理
隨著科技的發(fā)展,自動(dòng)化的科學(xué)含量不斷的提高。這將對(duì)工作人員的素質(zhì)提出更高的要求。工作人員不但要熟悉設(shè)備情況、檢修、規(guī)劃和設(shè)計(jì)等;而且還要懂得計(jì)算機(jī)以及具有一定技術(shù)水平。因此,必須從人員的培訓(xùn)力度、培訓(xùn)方式和培訓(xùn)內(nèi)容等著手。不斷提高工作人員的業(yè)務(wù)素質(zhì)和思想素質(zhì),才能勝任其工作崗位。
5.2維護(hù)管理
PLC控制系統(tǒng)的可靠性,其主要因素還是要做好后期的維護(hù)管理工作,維護(hù)設(shè)備主要部位:供電電源,外部環(huán)境、安裝狀態(tài)、電源(Ps)、中央處理單元(CPU)、信號(hào)模板(SM)及壽命元件輸人、輸出中間繼電器等外圍設(shè)備等。
6結(jié)束語(yǔ)
提高PLC控制系統(tǒng)的可靠性的方法很多,不同的可編程控制器,方法會(huì)略有不同;但只要在實(shí)際工作中,善于觀察,善于總結(jié)積累經(jīng)驗(yàn),就可以充分考慮到對(duì)PLC.的各種不利因素,在實(shí)際應(yīng)用中采取適當(dāng)措施;使控制系統(tǒng)可靠、安全地運(yùn)行,并能減少大量后期維修工作。
