First, FX-50DU is a part number for an old Mitsubishi terminal, so you might get more responses in that forum. Second, have you verified the cables connecting this device to the controller? And what controller is it?

hello, it is a FX-48mr es controller I have now make the screen load to menu by burning the data to eprom, now it still says communication error occurs, the new cable is a commercial cable, and the other was soldered up, they both say same message, I cant remember if the logic controller has to have something in the ladder to enable the screen or not. im not sure what problem is im sure it worked before, I have tryed it with another plc also. thanks for help.
