To be able to establish connection, you need to install USB driver.

There is a button to do this within U90 ladder software as shown in the photo below (Controller / M90 OPLC SETTINGS).

Make sure you use the same COM port number in U90 PC communication settings.

Hi Meetto

If the port is COM17 in device manager then you must select COM17 in the unitronics program communication settings.

However I think that the program only accepts COM ports up to 16.

Try changing the COM port in device manager to an unused port below 16 and match the settings in the Unitronics program

Dear Sir/madam,

I changed the virtual port setting in device manager to COM 2 and now it is working. Thank you for the time.
