4.響應(yīng)速度的要求
PLC的掃描工作方式引起的延遲可達2-3個掃描周期。對于大多數(shù)應(yīng)用場合來說,PLC的響應(yīng)速度都可以滿足要求,不是主要問題。然而對于某些個別場合,則要求考慮PLC的響應(yīng)速度。為了減少PLC的I/O響應(yīng)的延遲時間,可以選用掃描速度高的PLC,或選用具有高速I/O處理功能指令的PLC,或選用具有快速響應(yīng)模塊和中斷輸入模塊的PLC等。
5.系統(tǒng)可靠性的要求
對于一般系統(tǒng)PLC的可靠性均能滿足。對可靠性要求很高的系統(tǒng),應(yīng)考慮是否采用冗余控制系統(tǒng)或熱備用系統(tǒng)。
6.機型統(tǒng)一
一個企業(yè),應(yīng)盡量做到PLC的機型統(tǒng)一。主要考慮以下三個方面的問題:
(l)同一機型的PLC,其編程方法相同,有利于技術(shù)力量的培訓和技術(shù)水平的提高。
(2)同一機型的PLC,其模塊可互為備用,便于備品備件的采購和管理。
(3)同一機型的PLC,其外圍設(shè)備通用,資源可共享,易于聯(lián)網(wǎng)通信,配上位計算機后易于形成一個多級分布式控制系
