IS215UCVEH2A可編程控制器的主要特點(diǎn)
1、可靠性高
PLC的MTBF般在40000~50000h以上,西門子、ABB、松下等微小型PLC可達(dá)10萬h以上,而 且均有完善的自診斷功能,判斷故障迅速,便于維護(hù)。
2、模塊化組合靈活
可編程控制器是系列化產(chǎn)品,通常采用模塊結(jié)構(gòu)來完成不同的任務(wù)組合。I/O從8~8192點(diǎn), 有多種機(jī)型、多種功能模板可靈活組合,結(jié)構(gòu)形式也是多樣的。
3、功能強(qiáng)
PLC應(yīng)用微電子技術(shù)和微計(jì)算機(jī),簡(jiǎn)單型式都具有邏輯、定時(shí)、計(jì)數(shù)等順序控制功能?;?型式再加上模擬I/O、基本算術(shù)運(yùn)算、通信能力等。復(fù)雜型式除了具有基本型式的功能外,還具有擴(kuò)展的計(jì)算能力、多級(jí)終端機(jī)制、智能I/O、PID調(diào)節(jié)、過程監(jiān)視、網(wǎng)絡(luò)通信能力、遠(yuǎn)程I/O、多處理器和高速數(shù)據(jù)處理能力。
4、編程方便
PLC適用針對(duì)業(yè)控制的梯形圖、功能塊圖、指令表和順序功能表圖(SFC)編程,不需要太多 的計(jì)算機(jī)編程知識(shí)。新的編程作站配有綜合的軟件具包,并可在任何兼容的個(gè)人計(jì)算機(jī) 上編程。
PLC是應(yīng)用面很廣,發(fā)展非常迅速的業(yè)自動(dòng)化裝置,在廠自動(dòng)化(FA)和計(jì)算機(jī)集成制造 系統(tǒng)(CIMS)內(nèi)占重要地位。今天的PLC功能,遠(yuǎn)不僅是替代傳統(tǒng)的繼電器邏輯。
