為了處理急需響應(yīng)的輸入信號(hào)，PLC有種種措施。不同的PLC措施也不完全相同，提高響應(yīng)速度的效果也不同。一般的作法是采用輸入中斷，然后再輸出即時(shí)刷新，即中斷程序運(yùn)行后，有關(guān)的輸出點(diǎn)立即刷新，而不等到整個(gè)程序運(yùn)行結(jié)束后再刷新。

這個(gè)效果可從兩個(gè)方面來衡量：一是能否對(duì)幾個(gè)輸入信號(hào)作快速響應(yīng)；二是快速響應(yīng)的速度有多快。多數(shù)PLC都可對(duì)一個(gè)或多個(gè)輸入點(diǎn)作快速響應(yīng)，快速響應(yīng)時(shí)間僅幾個(gè)毫秒。性能高的、大型的PLC響應(yīng)點(diǎn)數(shù)更多。

工作速度關(guān)系到PLC對(duì)輸入信號(hào)的響應(yīng)速度，是PLC對(duì)系統(tǒng)控制是否及時(shí)的前提?？刂撇患皶r(shí)，就不可能準(zhǔn)確與可靠，特別是對(duì)一些需作快速響應(yīng)的系統(tǒng)。這就是把工作速度作為PLC指標(biāo)的原因。
