Hi Oktay,
To troubleshoot the error 'Error: EtherInit: Ether ID <ID>: Registration Error 2', you can try the following steps:
- Ensure that the IP addresses for the Real-Time UDP Configuration block and the TCP/IP Target Address are distinct from each other and from any other IP addresses that are already in use.
- It is recommended to place real-time UDP communication and target-host communication on different sub-networks to avoid interference.
- If you want to send data to the host instead of another real-time device, then you can try using Legacy UDP blocks instead.
I hope this helps!
