記憶接通延時(shí)定時(shí)器TONR(Retentive On—Delay Timer)
記憶接通延時(shí)定時(shí)器對(duì)定時(shí)器的狀態(tài)具有記憶功能,它用于對(duì)許多間隔的累計(jì)定時(shí)。*掃描或復(fù)位后上電周期,定時(shí)器位為OFF,當(dāng)前值為0。當(dāng)輸入端接通時(shí),當(dāng)前值從0開始計(jì)時(shí)。當(dāng)輸入端斷開時(shí),當(dāng)前值保持不變。當(dāng)輸入端再次接通時(shí),當(dāng)前值從上次的保持值繼續(xù)計(jì)時(shí),當(dāng)前值累計(jì)達(dá)到設(shè)定值時(shí),定時(shí)器位ON并保持,只要輸入端繼續(xù)接通,當(dāng)前值可繼續(xù)計(jì)數(shù)到32 767。

需要注意的是,斷開輸入端或斷開電源都不能改變TONR定時(shí)器的狀態(tài),只能用復(fù)位指令R對(duì)其進(jìn)行復(fù)位操作。
