Download from the plc, pull the program from the PLC to my computer. On the Set address menu I have Sys and USB set. I have tried Unity Pro and Unity Loader. I have tried to reinstall the USB driver. I have tried two different computers. and on both VM and the regular OS.

Also sorry for the confusion not a usb drive, a usb cable, like a printer cable.

I am not able to connect via USB

it is called uploading when transferring from PLC to PC.



try TCP/IP with address 90.0.0.1 when the PLC is plugged in by USB

or 90.0.0.2
