Why is communication error 4 occurring on my milling machine?
Error description
The remote programme displays the error message "Communication error no. 4 Timout when receiving a character".
Causes of errors
The error occurs if the programme cannot establish a connection to the milling machine.
Troubleshooting
The error often occurs because the remote programme has already been started. In this case, the second instance of the programme cannot access the milling machine.
- Make sure that the remote programme is only started once.
- Ensure that the milling machine is switched on.
- Ensure that the COM cable is connected to the router and the computer.
