Re: Modbus RS485 prompts: Call to CreateFile() returned erro
HI - I realise that this is a very old topic but I stumbled across it by typing in the error code that I am getting. I am using a T7A HMI. I have set the COM Port to COM2 and set the COM2 to use RS485. (see screen shots below) Any ideas what the issue could be?
