I/O(輸入/輸出部件)(I/O模塊:接口電路、I/O映像存儲(chǔ)器)
——CPU與現(xiàn)場(chǎng)I/O裝置或其他外部設(shè)備之間的連接部件。PLC提供了各種操作電平與驅(qū)動(dòng)能力的I/O模塊,以及各種用途的I/O組件供用戶選用:
輸入/輸出電平轉(zhuǎn)換
電氣隔離
串/并行轉(zhuǎn)換
數(shù)據(jù)傳送
A/D、D/A轉(zhuǎn)換
誤碼校驗(yàn)
其他功能模塊
I/O模塊可與CPU放在一起,也可遠(yuǎn)程放置。通常,I/O模塊上還具有狀態(tài)顯示和I/O接線端子排。

編程器等外部設(shè)備
編程器——PLC開(kāi)發(fā)應(yīng)用、監(jiān)測(cè)運(yùn)行、檢查維護(hù)*的工具
作用: 用于用戶程序的編制、編輯、調(diào)試、檢查和監(jiān)視
通過(guò)鍵盤(pán)和顯示器去檢測(cè)PLC內(nèi)部狀態(tài)和參數(shù)
通過(guò)通訊端口與CPU,實(shí)現(xiàn)與PLC的人機(jī)對(duì)話
分類(lèi): 簡(jiǎn)單型——只能聯(lián)機(jī)編程;只能用指令清單編程
智能型——既可聯(lián)機(jī)(Online),也可脫機(jī)(Offline)編程;可以采用指令清單(語(yǔ)句表)、梯形圖等語(yǔ)言編程。??芍苯右?strong>電腦作為編程器,安裝相關(guān)的編程軟件編程
注意: 編程器不直接加入現(xiàn)場(chǎng)控制運(yùn)行。一臺(tái)編程器可開(kāi)發(fā)、監(jiān)護(hù)許多臺(tái)PLC的工作。
