Hi,

I'm trying to make an UDP Receiver model on my Simulink Real Time Target. Here is the basic model to receive message with UDP Protocol that I build:

When I load this model to my real time target and run it, I get errors like this:

I didn't find any solution in other topics related to my problem. Is there any possible solution? Hpow can i fix it? Maybe the model I built up is incorrect, so you would consider them also.

Thanks to all.

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!
