What operating system are you using? Sometimes Medoc doesn't play well with the new windows operating systems. Also make sure that you don't have some other program open that is using the COM port, and if you use Allen-Bradley software on the PC you may have to uninstall the COM port and then reinstall it to get rid of the AB drivers and use the regular windows COM port drivers.

So you're trying to communicate with the PLC through the HMI? Then it sounds like the new HMI has an incorrect setting. I would compare settings between the new HMI and the old HMI on the machine that you can communicate with.
