描述

三菱FX機(jī)型可編程控制器中的定時(shí)器是對(duì)機(jī)內(nèi)1ms、10ms、100ms等不同規(guī)格時(shí)鐘脈沖累加計(jì)時(shí)的。定時(shí)器除了占有自己編號(hào)的存儲(chǔ)器位外,還占有一個(gè)設(shè)定值寄存器和一個(gè)當(dāng)前值寄存器。

具體工作歷程

定時(shí)器滿足計(jì)時(shí)條件時(shí)開(kāi)始計(jì)時(shí),當(dāng)前值寄存器則開(kāi)始計(jì)數(shù),當(dāng)它的當(dāng)前值與設(shè)定值寄存器存放的設(shè)定值相等時(shí)定時(shí)器動(dòng)作,其常開(kāi)觸點(diǎn)接通,常閉觸點(diǎn)斷開(kāi),并通過(guò)程序作用于控制對(duì)象,達(dá)到時(shí)間控制的目的。

定時(shí)器的類(lèi)型：有通用型、積算型兩大類(lèi)

通用定時(shí)器：FX系列PLC有100ms、10ms、1ms3種定時(shí)器，不同型號(hào)PLC的不同3種定時(shí)器的范圍不同，而同一型號(hào)的PLC的3種定時(shí)器的范圍還可由特殊輔助繼電器M8028的狀態(tài)改變。
