描述
它在執(zhí)行掃描操作時(shí)對(duì)內(nèi)部元件X、Y、M、S、T、C的信號(hào)進(jìn)行計(jì)數(shù)。當(dāng)計(jì)數(shù)次數(shù)達(dá)到計(jì)數(shù)器的設(shè)定值時(shí),計(jì)數(shù)器觸點(diǎn)動(dòng)作,用于控制系統(tǒng)完成相應(yīng)的功能。低速計(jì)數(shù)器不但可以記錄來(lái)自輸入端子(輸入繼電器)的開(kāi)關(guān)信號(hào),而且可以記錄PLC內(nèi)部其他元件的觸點(diǎn)信號(hào)。
內(nèi)部計(jì)數(shù)器按其被記錄開(kāi)關(guān)量的頻率分類,可分為低速計(jì)數(shù)器和高速計(jì)數(shù)器。
1)低速計(jì)數(shù)器
有四類:
16位通用增計(jì)數(shù)器:C0∽C99(100點(diǎn));設(shè)定值區(qū)間為K1∽K32767
16位停電保持增計(jì)數(shù)器:C100∽C199(100點(diǎn));設(shè)定區(qū)間為K1∽K32767
32位通用增/減雙向計(jì)數(shù)器:C200∽C219(20點(diǎn));設(shè)定值區(qū)間為K-2147483648∽+214783648
32位停電保持增/減雙向計(jì)數(shù)器:C220∽C234(15點(diǎn));設(shè)定值區(qū)間為K-2147483648∽+214783648
2)內(nèi)部高速計(jì)數(shù)器(C)
高速計(jì)數(shù)器只能刻錄約定的經(jīng)輸入端子(輸入繼電器)送入的外部信號(hào),而且這個(gè)信號(hào)的頻率可以高達(dá)幾千赫。還可以從輸入端子直接進(jìn)行復(fù)位的操作。
高速計(jì)數(shù)器編號(hào)為C235∽C255共21點(diǎn),均為32位增/減雙向計(jì)數(shù)器,其增計(jì)數(shù)還是減計(jì)數(shù)由指定的特殊輔助繼電器決定或由指定的輸入端子決定,其設(shè)定區(qū)間為K-2147483648∽+214783648。
