很多的情況下我們總喜歡采用串并轉換芯片來進行傳輸,這種情況下不需要我們進行過于復雜的寄存器設置了,而直接通過數據傳送指令進行數據交流,但在通信中并不是一個十分可行的辦法,因為在發送數據的時候對方的PLC必須一直等待你的數據輸出,它不能去做其他的工作。 當你在看書的時候,你聽到有人敲門、你停下手上的事情、去打開門、并同敲門者對話、這個時候響了、你示意接個、在接完后、回過頭來同敲門者繼續對話、對話完畢后、你再繼續看你的書,這種情況我們把它稱為中斷,它具有性,也具有優先性,PLC具備了這樣的功能。它的特點在于我們在設備的操作過程中可能會遇到緊急的突發事件,我們要立刻的停下手上的工作,去處理更重要的事情,這種情況是我們經常所遇到的,PLC在去執行緊急的任務時,總會先保存目前的狀態,比如程序的地址,CPU的累加器數據等,就像我們去開門時要記下我們看的書在第幾頁了或者干脆作個記號,因為我們待會還要繼續接著看后面的書。CPU總是按照我們的意愿去做應該做的事情,但你錯誤的給它一件事情,它也會同樣的去做,這一點我們必須注意。 中斷并不是只有一個,有時會同時存在幾個中斷,中斷具有優先的級別,他們會根據人的要求去執行更高級別的中斷。這種中斷中的中斷也就形成了中斷嵌套。當然中斷的級別根據各種PLC內部CPU的資源有關,同時也跟堆棧的容量大小也有關系。 中斷的內容有很多種,比如外部中斷、通信中的發送和接受中斷、定時和計數的時鐘中斷、還有WDT復位中斷等,它們豐富了CPU在處理各種事務時響應種類。這樣講也許你并不能*理解中斷的內部結構和操作順序,我們做一個小小的例子來說明. 每一個設備總是不會忘記有一個按鈕,它也是在我們遇到緊急情況時使用的,那就是急停按鈕。當我們遇到人身事故和意外情況時我們只要按下它,機器立即停止所有的操作,并等待處理完意外后再恢復操作。急停按鈕連接PLC內部CPU的內部I/O接口上,當按鈕給CPU一個外部觸發信號時,CPU對I/O進行再次檢測,當確認有外部觸發信號時,CPU保護現場并將程序計數器自動轉到相應的外部I/O中斷程序中去,當外部中斷程序處理完畢,程序計數器返回到主程序繼續工作。有一點可以說明的是我們一般會把急停按鈕的外部中斷升至zui高級別,從而保證安全。 當我們在工作完一個工件時,給PLC一個信號,將PLC的內部計數器加1
來計算我們一天的工作量時,一個簡單的計數器能解決問題,當然它們也能夠在掉電的情況下保持數據,促使數據不丟失,這也是我們所渴望的。 PLC還具有高級計數器的功能,當我們在接受一些高速的數據時,這里所說的高速是在在微秒級的數據,比如條碼掃描機在不斷的掃描數據,數據處理器DSP計算的高速信號等,我們就要采用到高級計數器來幫助我們進行計數。它在PLC執行程序時一旦發現高級計數器對應的中斷,就會立即放下手上的工作。經過再次編程的梯形圖程序說明我們在執行程序時高級計數器會自動的執行對應的工作,從而將高級計數器的級別升至高一級別。 你也許聽過太多的這個詞:“死機”,大致的意思是CPU工作量過大,內部資源不足等情況造成程序無法運行。PLC也有類似的情況,在PLC內部有一個看門狗WDT,我們可以設置WDT一個程序運行的時間,當程序運行過程中出現程序跳轉錯誤時或者程序繁忙時,程序的運行時間超過WDT的設置時間,CPU轉而WDT復位狀態。程序重新開始運行,但對中斷不會進行破壞。 PLC的發展已經從單一的模式進入了通信的網絡時代,并同其它的工控網板和I/O卡板輕易的進行共享。組態軟件可以將所有的這些硬件連接起來,通過更直觀的動畫圖片來進行控制,并可以通過互聯網在異地進行控制,像神舟五號的發射就是采用這種辦法來使飛船升空。 更高層次的發展需要我們不斷的努力來取得。PLC的出現已經足足影響了幾代人,我們也從上一輩的經驗中獲取了更多的知識和教訓,來不斷的發展PLC技術,將它推向更高浪潮。 了解可用的PLC網絡的*選擇,其應用將確保有效率和靈活的控制系統設計??删幊踢壿嬁刂破鳎≒LC的)能夠支持多種通信方法的范圍,使之成為一個理想的控制和工業自動化和控制應用各種設施數據采集裝置。然而,有一些混亂,因為這么多的可能性存在。為了幫助消除這種混亂,讓我們的通訊名單,可什么時候他們會是的應用。 為了了解PLC的通信多功能性,讓我們首先定義描述的各種制度的用語: ASCII碼:這代表著信息交換。1,當字母“A”是傳播,例如,它會自動編碼為“65由發送設備”。接收設備轉換的“65”回答。因此,不同的設備可以相互通信既是使用ASCII代碼的其他長。 ASCII的模塊:這個智能PLC模塊是用于連接到PLC的通信也使用ASCII碼作為車輛等設備的能力。
