求助各位高手，F(xiàn)X3U編程口被觸摸屏占用了，想監(jiān)控程序每次都拔編程口換來換去，不方便，用觸摸屏穿透監(jiān)控反應(yīng)很慢，我買了一塊FX3U232 BD通信板監(jiān)控程序，電腦用USB轉(zhuǎn)232 端口已驅(qū)動好，硬件接線    2接3       3接2      5接5       問題是怎么樣都通信不上，求助大家指點(diǎn)
                                                                                                                                                                                                                                謝謝！

說一下我用的。FX3U-232ADP模塊，力特的USB轉(zhuǎn)COM口，完美通訊。編程線是三菱GOT觸摸屏下載線，只要在PLC編程軟件里設(shè)定COM口就可以了。 [attachment=147057]
