描述
1.輸入繼電器(X)
輸入繼電器是PLC中專門用來接收系統(tǒng)輸入信號的內(nèi)部虛擬繼電器。它由PLC工作原理來完成繼電器的功能。它在PLC內(nèi)部與輸入端子相連,它有無數(shù)的常開觸點和常閉觸點,這些動合、動斷觸點可在PLC編程時隨意使用。這種輸入繼電器不能用程序驅(qū)動,只能由輸入信號驅(qū)動。
FX系列PLC的輸入繼電器采用八進制編號。FX2N系列PLC帶擴展時最多可達184點輸入繼電器,其編號為X0∽X267。
2.輸出繼電器(Y)
輸出繼電器是PLC中專門用來將運算結(jié)果信號經(jīng)輸出接口電路及輸出端子,送達并控制外部負載的虛擬繼電器。它在PLC內(nèi)部直接與輸出接口電路相連,它有無數(shù)的動合觸點與動斷觸點,這些動合與動斷觸點可在PLC編程時隨意使用。外部倍無法直接驅(qū)動繼電器,它只能用程序驅(qū)動。
