Hello all,
When trying to establish a serial connection between GX Developer and a Mitsubishi PLC I am faced with the following error message: 'An unusable COM port was specified. Execute again after checking the COM port setting.'
I have checked the cable connection, everything seems fine. I have tried changing to another COM port but I get the same error message every time.
Can anyone help me ASAP? It would be very appreciated.
Cheers.
