描述

切斷PLC電源或從RUN(運(yùn)行)模式切換到PROG.(編程)模式時(shí)，定時(shí)器將被復(fù)位，其中的數(shù)據(jù)被清零。(如果需要保持當(dāng)前的操作狀態(tài)，請(qǐng)參見系統(tǒng)寄存器6)

當(dāng)觸發(fā)器(執(zhí)行條件)閉合時(shí)，定時(shí)器從設(shè)定值開始進(jìn)行減計(jì)數(shù)直至經(jīng)過值為零，然后在該時(shí)刻定時(shí)器觸點(diǎn)Tn(n為指定定時(shí)器的觸點(diǎn)編號(hào))變?yōu)镺N.(轉(zhuǎn)后)

如果在減計(jì)數(shù)的過程中觸發(fā)器(執(zhí)行條件)斷開，則操作停止、經(jīng)過值復(fù)位(清零)

可以在定時(shí)器線圈之后直接執(zhí)行OT指令。

設(shè)置定時(shí)器的時(shí)間

所設(shè)定的時(shí)間等于時(shí)間增量(計(jì)時(shí)單位)乘以定時(shí)器的設(shè)定值。

定時(shí)器的設(shè)定值為K1至K32767之間的十進(jìn)制整數(shù)。時(shí)間增量為0.001秒，則相應(yīng)的定時(shí)范圍是0.001秒到32.767秒。

示例:

當(dāng)設(shè)定值為K43時(shí)，定時(shí)時(shí)間為0.001X43=0.043秒

當(dāng)設(shè)定值為K500時(shí)，定時(shí)時(shí)間為0.001X500=0.5秒

編程時(shí)注意事項(xiàng)

在程序處理過程中定時(shí)器值遞減，應(yīng)編寫程序使一個(gè)掃描周期內(nèi)執(zhí)行一次遞減(如果使用了中斷程序或JP/LOOP等指令，使得程序在一個(gè)掃描周期內(nèi)沒有處理或產(chǎn)生多次出來，則不能得到正確的結(jié)果。)如果需要在一個(gè)掃描周期內(nèi)進(jìn)行多重處理，請(qǐng)參照系統(tǒng)寄存器4.在將定時(shí)器指令與ANS指令或POPS指令組合使用時(shí)，請(qǐng)注意表達(dá)式的正確性。
