首先,創(chuàng)建一個(gè)新工程,定義路徑和名稱,在設(shè)備選項(xiàng)中選定一個(gè)COM 口,進(jìn)行PLC連接。ET提供的設(shè)備連接向?qū)?duì)話框列出了工業(yè)生產(chǎn)常用的一些硬件設(shè)備(如PLC、板卡、智能儀表、變頻器等),并且已經(jīng)根據(jù)這些常用設(shè)備各自的通信協(xié)議制作了相應(yīng)的通信協(xié)議,使應(yīng)用人員從繁瑣的底層驅(qū)動(dòng)程序中解脫出來。選擇了西門子公司$7200系列PLC后,選擇通信方式,并給定設(shè)備名稱和地址,還要設(shè)置采樣時(shí)間和通信參數(shù)。
然后,進(jìn)行動(dòng)畫畫面的設(shè)計(jì)和變量的定義。雙擊數(shù)據(jù)詞典,定義和編寫系統(tǒng)所有變量。變量可以設(shè)為只讀、只寫和讀寫模式。對(duì)于既要采集PLC狀態(tài),又要實(shí)現(xiàn)對(duì)PLC的遠(yuǎn)程控制的變量設(shè)置為讀寫模式,而不需要向PLC發(fā)送命令的變量設(shè)置為只讀,這樣可以節(jié)省PLC掃描時(shí)間,加快系統(tǒng)進(jìn)程,提高PLC效率。繪制圖形畫面時(shí),雙擊畫面選項(xiàng),在彈出的繪圖環(huán)境下繪制與橡塑三輥壓延生產(chǎn)線相對(duì)應(yīng)的監(jiān)控畫面。系統(tǒng)監(jiān)控的設(shè)備較多,為更清楚明了地顯示不同設(shè)備的各個(gè)參數(shù),需要繪制多副畫面,既方便顯示,又方便現(xiàn)場操作員進(jìn)行控制。主畫面里利用ShowPicture(“畫面名”)函數(shù)實(shí)現(xiàn)對(duì)其他畫面的調(diào)用。繪制完流程畫面后,將系統(tǒng)與要監(jiān)控的參數(shù)和畫面中的變量一一對(duì)應(yīng)起來。這樣HMI組態(tài)基本完成。
