1．高速計(jì)數(shù)器概述

21點(diǎn)高速計(jì)數(shù)器C235～C255共用PLC的8個(gè)高速計(jì)數(shù)器輸入端X0～X7，某一輸入端同時(shí)只能供一個(gè)高速計(jì)數(shù)器使用。這21個(gè)計(jì)數(shù)器均為32位加/減計(jì)數(shù)器(見(jiàn)表3–7)。不同類型的高速計(jì)數(shù)器可以同時(shí)使用，但是它們的高速計(jì)數(shù)器輸入不能沖突。

高速計(jì)數(shù)器的運(yùn)行建立在中斷的基礎(chǔ)上，這意味著事件的觸發(fā)與掃描時(shí)間無(wú)關(guān)。在對(duì)外部高速脈沖計(jì)數(shù)時(shí)，梯形圖中高速計(jì)數(shù)器的線圈應(yīng)一直通電，以表示與它有關(guān)的輸入點(diǎn)已被使用，其他高速計(jì)數(shù)器的處理不能與它沖突?？捎眠\(yùn)行時(shí)一直為ON的M8000的常開(kāi)觸點(diǎn)來(lái)驅(qū)動(dòng)高速計(jì)數(shù)器的線圈。

當(dāng)X14為ON時(shí)，選擇了高速計(jì)數(shù)器C235，從表3–7可知，C235的計(jì)數(shù)輸入端是X0，但是它并不在程序中出現(xiàn)，計(jì)數(shù)信號(hào)不是X14提供的。
