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*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。
