首要，提示咱們留心下：億維UN200 CPU高速脈沖計(jì)數(shù)器輸入端接受電平為24V的編碼器，NPN和PNP的輸出都可以接入。
通常計(jì)數(shù)器受CPU掃描速度的影響，是依照次第掃描的辦法進(jìn)行作業(yè)。在每個(gè)掃描周期中，對(duì)計(jì)數(shù)脈沖只能進(jìn)行一次累加；對(duì)于脈沖信號(hào)的頻率比CPU的掃描頻率高時(shí)，假設(shè)仍選用通常計(jì)數(shù)器進(jìn)行累加，必然會(huì)扔掉許多對(duì)輸入脈沖信號(hào)。在CPU中，比照掃描頻率高的輸入信號(hào)的計(jì)數(shù)可也運(yùn)用高速計(jì)數(shù)器指令來(lái)完畢。
1．高速計(jì)數(shù)器指令 
TRICON 9853-610 高速計(jì)數(shù)器的指令包含：界說(shuō)高數(shù)計(jì)數(shù)器指令HDEF和實(shí)行高速計(jì)數(shù)指令HSC，如下表

(1) 界說(shuō)高速計(jì)數(shù)器指令HDEF
HDEF指令功用是為某個(gè)要運(yùn)用的高速計(jì)數(shù)器選定一種作業(yè)辦法。每個(gè)高速計(jì)數(shù)器在運(yùn)用前，都要用HDEF指令來(lái)界說(shuō)作業(yè)辦法，而且只能用一次。它有兩個(gè)輸入端：HSC為要運(yùn)用的高速計(jì)數(shù)器編號(hào)，數(shù)據(jù)類(lèi)型為字節(jié)型，數(shù)據(jù)計(jì)劃為0~5的常數(shù)，別離對(duì)應(yīng)HC0~ HC5;MODE為高速計(jì)數(shù)的作業(yè)辦法，數(shù)據(jù)類(lèi)型為字節(jié)型，數(shù)據(jù)計(jì)劃為0~11的常數(shù)，別離對(duì)應(yīng)12種作業(yè)辦法。當(dāng)容許輸入使能EN有用時(shí)，為指定的高速計(jì)數(shù)器HSC界說(shuō)作業(yè)辦法MODE。
（2）實(shí)行高速計(jì)數(shù)指令HSC 
TRICON 9853-610指令功用功用是依據(jù)與高速計(jì)數(shù)器有關(guān)的分外繼電器判定在操控辦法和作業(yè)狀況，使高速計(jì)數(shù)器的設(shè)置收效，依照指令的作業(yè)辦法的作業(yè)辦法實(shí)行計(jì)數(shù)操作。它有一個(gè)數(shù)據(jù)輸入端N：N為高速計(jì)數(shù)器的編號(hào)，數(shù)據(jù)類(lèi)型的字型，數(shù)據(jù)計(jì)劃為0~5的常數(shù)，別離對(duì)應(yīng)高速計(jì)數(shù)器HC0~HC5.當(dāng)容許輸入EN使能有用時(shí)，發(fā)起N號(hào)高速計(jì)數(shù)器作業(yè)。
2．高速計(jì)數(shù)器的輸入端
高速計(jì)數(shù)器的輸入端不像通常輸入端那樣有用戶(hù)界說(shuō)，而是由體系指定的輸入點(diǎn)輸入信號(hào)，每個(gè)高速計(jì)數(shù)器對(duì)它所支撐的脈沖輸入端，方向操控，復(fù)位和發(fā)起都有專(zhuān)用的輸入點(diǎn)，經(jīng)過(guò)比照或間斷完畢預(yù)訂的操作。每個(gè)高速計(jì)數(shù)器專(zhuān)用的輸入點(diǎn)如下表：
