回路調(diào)試注意事項(xiàng)
(1)對(duì)開關(guān)量輸入輸出回路,要注意保持狀態(tài)的*性原則,通常采用正邏輯原則,即 當(dāng)輸入輸出帶電時(shí),為“ON"狀態(tài),數(shù)據(jù)值為“1";反之,當(dāng)輸入輸出失電時(shí),為“OFF"狀態(tài), 數(shù)據(jù)值為“0"。這樣,便于理解和維護(hù)。
(2)對(duì)負(fù)載大的開關(guān)量輸入輸出模塊應(yīng)通過(guò)繼電器與現(xiàn)場(chǎng)隔離,即現(xiàn)場(chǎng)接點(diǎn)盡量不要 直接與輸入輸出模塊連接。
(3)使用PLC提供的強(qiáng)制功能時(shí),要注意在測(cè)試完畢后,應(yīng)還原狀態(tài);在同一時(shí)間內(nèi),不 應(yīng)對(duì)過(guò)多的點(diǎn)進(jìn)行強(qiáng)制操作,以免損壞模塊。
