Networking issues are the ones that take most time and effort to debug.

Your first steps should be:

1. Go to online mode and determine if the transmissions are received by the PLC. To do that press the touch screen for 5 seconds (for non-touch screen press the (i) button), then enter the code (default 1111), go to serial-->monitor. In that screen you can see the actual Tx/Rx communications.

2. If the transmission is OK, start debugging your code - comms configuration, baud rates, Scan commands etc.

3. If you still cannot solve this issue, please send your application to support@unitronics.com
