1.輸入/輸出單元
輸入/輸出單元通常也稱I/O單元或I/O模塊,是PLC與工業生產現場之間的連接部件。
PLC通過輸入接口可以檢測被控對象的各種數據,以這些數據作為PLC對被控制對象進行控制的依據;同時PLC又通過輸出接口將處理結果送給被控制對象,以實現控制目的。
由於外部輸入設備和輸出設備所需的信號電平是多種多樣的,而PLC內部CPU的處理的信息只能是標準電平,所以I/O接口要實現這種轉換。
I/O接口一般都具有光電隔離和濾波功能,以提高PLC的抗幹擾能力。另外,I/O接口上通常還有狀態指示,工作狀況直觀,便於維護。
PLC提供了多種操作電平和驅動能力的I/O接口,有各種各樣功能的I/O接口供用戶選用。I/O接口的主要類型有:數字量(開關量)輸入、數字量(開關量)輸出、模擬量輸入、模擬量輸出等。
常用的開關量輸入接口按其使用的電源不同有三種類型:直流輸入接口、交流輸入接口和交/直流輸入接口。
常用的開關量輸出接口按輸出開關器件不同有三種類型:是繼電器輸出、晶體管輸出和雙向晶閘管輸出。
繼電器輸出接口可驅動交流或直流負載,但其響應時間長,動作頻率低;而晶體管輸出和雙向晶閘管輸出接口的響應速度快,動作頻率高,但前者只能用於驅動直流負載,後者只能用於交流負載。
PLC的I/O接口所能接受的輸入信號個數和輸出信號個數稱為PLC輸入/輸出(I/O)點數。I/O點數是選擇PLC的重要依據之一。當係統的I/O點數不夠時,可通過PLC的I/O擴展接口對係統進行擴展。
2.通信接口
PLC配有各種通信接口,這些通信接口一般都帶有通信處理器。
PLC通過這些通信接口可與監視器、打印機、其它PLC、計算機等設備實現通信。
PLC與打印機連接,可將過程信息、係統參數等輸出打印;與監視器連接,可將控制過程圖像顯示出來;與其它PLC連接,可組成多機係統或連成網絡,實現更大規模控制。
與計算機連接,可組成多級分布式控制係統,實現控制與管理相結合。遠程I/O係統也配備相應的通信接口模塊。
3.智能接口模塊
智能接口模塊是一獨立的計算機係統,它有自己的CPU、係統程序、存儲器以及與PLC係統總線相連的接口。
它作為PLC係統的一個模塊,通過總線與PLC相連,進行數據交換,並在PLC的協調管理下獨立地進行工作。
PLC的智能接口模塊種類很多,如:高速計數模塊、閉環控制模塊、運動控制模塊、中斷控制模塊等。
