描述
PLC內(nèi)有很多的輔助繼電器,其線圈與輸出繼電器一樣,由PLC內(nèi)各軟元件的觸點驅(qū)動。輔助繼電器也稱中間繼電器,它沒有向外的任何聯(lián)系,只供內(nèi)部編程使用。它的電子常開/常閉觸點使用次數(shù)不受限制。但是,這些觸點不能直接驅(qū)動外部負(fù)載,外部負(fù)載的驅(qū)動必須通過輸出繼電器來實現(xiàn)。如下圖中的M300,它只起到一個自鎖的功能。在FX2N中普遍途采用M0~M499,共500點輔助繼電器,其地址號按十進(jìn)制編號。輔助繼電器中還有一些特殊的輔助繼電器,如掉電繼電器、保持繼電器等,在這里就不一一介紹了。
