 <description><![CDATA[14楼说的完全正确，关键的一句话是“应该是用PNP时要用外接电源,外接电源负极接24V+端子”。]]></description>

14楼你好!我用过,这台机器是我改的,我厂原来PLC是西门子S5的,所有传感器都是PNP的.所以绝对正确.

NPN,PNP多可以.用NPN时可利用PLC内部电源.用PNP时要用外接电源,外接电源负极接COM,编码器X,Y,Z接相应输入点.

你好!请教:以上是你的观点.用PNP时要用外接电源,外接电源负极接COM,编码器X,Y,Z接相应输入点.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; ..]]></description>
