Hello..I am new to Plc.I have Mitsubishi Melsec Fx3Ga-40MR PLC controlling a machine for packing powder.Currently the Plc has issue which power indicator on but run and error indicators off.I tried to connect it using usb(Easy driver) with my laptop(GX works 2 software) but got no communication.I tried to access device manager in my laptop,Usb socket driver under usb port not showing.
The weird thing is I can connect with other machine which exactly the same as Im troubleshooting now using same cable and software.
I suspect the Plc has lost its program so I need to download the program to it.
For your information,The inputs and outputs of the Plc all indicators not turn on.
I checked got 24Vdc from external power supply.
Sensors connection to input port of Plc all are functioning.
May I get your fellows expert and experienced help about this issue?
Thank you.
