４、生產(chǎn)過程的監(jiān)控和管理　　PLC可以通過通迅接口與顯示終端和打印機(jī)等外設(shè)相連。顯示器作為人機(jī)界面（HMI）是一種內(nèi)含微處理芯片的智能化設(shè)備，它與PLC相結(jié)合可取代電控柜上眾多的控制按鈕、選擇開關(guān)、信號指示燈，及生產(chǎn)流程模擬屏和電控柜內(nèi)大量的中間繼電器和端子排。所有操作都可以在顯示屏上的操作元件上進(jìn)行。

PLC可以方便、快捷地對生產(chǎn)過程中的數(shù)據(jù)進(jìn)行采集、處理，并可對要顯示的參數(shù)以二進(jìn)制、十進(jìn)制、十六進(jìn)制、ascii 字符等方式進(jìn)行顯示。在顯示畫面上，通過圖標(biāo)的顏色變化反應(yīng)現(xiàn)場設(shè)備的運(yùn)行狀態(tài)，如閥門的開與關(guān)，電機(jī)的啟動與停止，位置開關(guān)的狀態(tài)等。PID回路控制用數(shù)據(jù)、棒圖等綜合方法反映生產(chǎn)過程中量的變化，操作人員通過參數(shù)設(shè)定可進(jìn)行參數(shù)調(diào)整，通過數(shù)據(jù)查詢可查找任一時刻的數(shù)據(jù)記錄，通過打印可保存相關(guān)的生產(chǎn)數(shù)據(jù)，為今后的生產(chǎn)管理和工藝參數(shù)的分析帶來便利。５、網(wǎng)絡(luò)特性　　PLC可以實(shí)現(xiàn)多臺PLC之間或多臺PLC與一臺計(jì)算機(jī)之間的通訊聯(lián)網(wǎng)要求，從而組成多級分布式控制系統(tǒng)，構(gòu)成工廠自動化網(wǎng)絡(luò)?！　?1) ?通過通訊模塊、上位機(jī)以及相應(yīng)的軟件來實(shí)現(xiàn)對控制系統(tǒng)的遠(yuǎn)距離監(jiān)控?！　?2) ?通過調(diào)制解調(diào)器和公用電話網(wǎng)與遠(yuǎn)程客戶端計(jì)算機(jī)相連，從而使管理者可通過電話線對控制系統(tǒng)進(jìn)行遠(yuǎn)距離監(jiān)控。 ?結(jié)束語　　可編程控制器作為一種通用的工業(yè)控制器，它可用于所有的工業(yè)領(lǐng)域。當(dāng)前國內(nèi)外已經(jīng)廣泛的將可編程控制器成功地應(yīng)用到機(jī)械、冶金、石油、化工、紡織、交通、電力、軍事等各個領(lǐng)域，并取得了可觀的技術(shù)濟(jì)濟(jì)效益。而且它還代表當(dāng)今電氣控制技術(shù)的世界先進(jìn)水平，它已與數(shù)控技術(shù)。
