UDP- recovering from timeout-no response or answer

[New2Labview]

 Hello all , I have written a labview application that sends out write and read commands to a unit under test via UDP  communication. The program works great but when the unit under test doesnt respond back the udp read function times out and my program bombs out from that point on because all further udp writes and reads simply wont work anymore.   

 My basic labview question is how can I make my program continue - go onto the next UDP write -read when the previous read has timed out because its gotten no answer back  from my unit under test ? 

Thanks,  John

It sounds like you need to evaluate the error code returned from the UDP Read function. If it is 56, then the read "timed out". In your case this is not an error, so you would filter for it.

There is a VI  (examples\comm\UDP.llb\no timeout error.vi)  that will do this for you.

 Thanks Phillip , I did end up looking for an error 56 and the program works great now......thanks again.

Hi. About that example, where can i find it? I'm having that problem but using SMTP protocols, the error comes up with the block "Send".
