描述
5電源模塊
PLC電源用于為PLC各模塊的集成電路提供工作電源。同時,有的還為輸入電路提供24V的工作電源。電源輸入類型有:交流電源(220VAC或110VAC),直流電源(常用的為24VDC)。
6底板或機架
大多數(shù)模塊式PLC使用底板或機架,其作用是:電氣上,實現(xiàn)各模塊間的聯(lián)系,使CPU能訪問底板上的所有模塊,機械上,實現(xiàn)各模塊間的連接,使各模塊構(gòu)成一個整體。
7 PLC系統(tǒng)的其它設(shè)備
7.1編程設(shè)備:編程器是PLC開發(fā)應(yīng)用、監(jiān)測運行、檢查維護不可缺少的器件,用于編程、對系統(tǒng)作一些設(shè)定、監(jiān)控PLC及PLC所控制的系統(tǒng)的工作狀況,但它不直接參與現(xiàn)場控制運行。小編程器PLC一般有手持型編程器,目前一般由計算機(運行編程軟件)充當(dāng)編程器。也就是我們系統(tǒng)的上位機。
7.2人機界面:最簡單的人機界面是指示燈和按鈕,目前液晶屏(或觸摸屏)式的一體式操作員終端應(yīng)用越來越廣泛,由計算機(運行組態(tài)軟件)充當(dāng)人機界面非常普及。
8 PLC的通信聯(lián)網(wǎng)
依靠先進的工業(yè)網(wǎng)絡(luò)技術(shù)可以迅速有效地收集、傳送生產(chǎn)和管理數(shù)據(jù)。因此,網(wǎng)絡(luò)在自動化系統(tǒng)集成工程中的重要性越來越顯著,甚至有人提出”網(wǎng)絡(luò)就是控制器”的觀點說法。
PLC具有通信聯(lián)網(wǎng)的功能,它使PLC與PLC之間、PLC與上位計算機以及其他智能設(shè)備之間能夠交換信息,形成一個統(tǒng)一的整體,實現(xiàn)分散集中控制。多數(shù)PLC具有RS-232接口,還有一些內(nèi)置有支持各自通信協(xié)議的接口。PLC的通信現(xiàn)在主要采用通過多點接口(MPI)的數(shù)據(jù)通訊、PROFIBUS或工業(yè)以太網(wǎng)進行聯(lián)網(wǎng)。
