If you cannot connect to an M340 with the Unity Loader through TCP/IP and there are no issues connecting with Control Expert, it is recommended to check the firewall settings to ensure that Unity Loader is not being blocked.
There have been reported issues where some firewalls (i.e., Firewall Timed Group, etc. ) are blocking Unity Loader from accessing the M340 over TCP/IP.
