 這個(gè)小程序在PC一投入運(yùn)行就開始工作。其操作的關(guān)鍵在于專用輔助繼電器M8013，這個(gè)元件提供一個(gè)周期為1秒的脈沖。計(jì)數(shù)器根據(jù)這個(gè)“時(shí)鐘脈沖”對(duì)過去的時(shí)間以秒計(jì)數(shù)。如果這個(gè)計(jì)數(shù)器到了60就復(fù)位，便可知道過去了一分鐘。

    如果第二個(gè)計(jì)數(shù)器對(duì)計(jì)數(shù)器C000復(fù)位次數(shù)計(jì)數(shù)，則可知道過去了多少分鐘。

    因此，接下來的邏輯與前面相同，只是用C001來計(jì)“分”。再進(jìn)一步，用C002來計(jì)“時(shí)”，從而完成一個(gè)完全獨(dú)立的時(shí)鐘。時(shí)間可從3個(gè)計(jì)數(shù)器上直接讀出。使C002的“設(shè)定”值等于24，就得到一個(gè)24小時(shí)時(shí)鐘，或者設(shè)定值等于12時(shí)，一個(gè)標(biāo)準(zhǔn)的12小時(shí)時(shí)鐘就能工作了。
