中斷的內(nèi)容有很多種，比如外部中斷、通信中的發(fā)送和接受中斷、定時和計數(shù)的時鐘中斷、還有WDT復位中斷等，它們豐富了在處理各種事務時響應種類。這樣講也許你并不能完全理解中斷的內(nèi)部結(jié)構(gòu)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(nèi)部的內(nèi)部I/O接口上，當按鈕給一個外部觸發(fā)信號時，對I/O進行再次檢測，當確認有外部觸發(fā)信號時，保護現(xiàn)場并將程序計數(shù)器自動轉(zhuǎn)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(shù)器返回到主程序繼續(xù)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(nèi)部計數(shù)器加1來計算我們的工作量時，一個簡單的計數(shù)器能解決問題，當然它們也能夠在掉電的情況下保持數(shù)據(jù)，促使數(shù)據(jù)不丟失，這也是我們所渴望的。
PLC還具有計數(shù)器的功能，當我們在接受一些高速的數(shù)據(jù)時，這里所說的高速是在在微秒級的數(shù)據(jù)，比如條碼掃描機在不斷的掃描數(shù)據(jù)，數(shù)據(jù)處理器DSP計算的高速信號等，我們就要采用到計數(shù)器來幫助我們進行計數(shù)。它在PLC執(zhí)行程序時一旦發(fā)現(xiàn)計數(shù)器對應的中斷，就會立即放下手上的工作。經(jīng)過再次編程的梯形圖程序說明我們在執(zhí)行程序時計數(shù)器會自動的執(zhí)行對應的工作，從而將計數(shù)器的級別升至高一級別。
