Thank you for reply, I have tried a USB-Serial adapter and have tried configuring to various COM ports with no success I get "Cannot communicate with PLC. Execute again after checking the connections with the PLC <ES:01802007>" OR "An unusuable COM port was specified. Execute again after checking the COM port settings. <ES:01808009> Any ideas about where I am going wrong. I am using Vista Ultimate OS

Whose USB to serial adapter are you using? Are the drivers updated for Vista? Are you sure you're using the right COM port that matches your USB adapter setting? And of course, is RSLinx running? And most importantly, is this 64-bit Windows? Mitsu titles don't run on 64-bit Vista.
