由PLC的工作原理可知,当输入端接动合触点,在PLC工作时,若输入端的动合触点闭合,则对应于该输入端子的输入继电器线圈得电,它的动合触点闭合、动断触点断开;当输入端接动断触点且在PLC工作时,若输入端的动断触点未动作,则对应于该输入端的输入继电器线圈得电,它的动合触点闭合、动断触点断开。如果该动断触点与输出继电器线圈串联,则输出继电器线圈不能得电。因而,用PLC控制电动机的启停,如果停止按钮用动断触点,则与控制电动机的接触器相接的PLC输出继电器线圈应与停止按钮相接的输入端子相对应的动合触点串联。在继电接触控制中,停止按钮和热继电器均用动断触点,为了与继电接触控制的控制电路相一致,在PLC梯形图中,同样也用动断触点,这样一来,与输入端相接的停止按钮和热继电器触点就用动合触点。在识读程序时注意这一点。
