Multicast UDP on ZYNQ 9651 or 9068 cRIO

[MrJackHamilton]

UDP Multicast is supported by the Zynq base cRIO's however there is a twist that will give you an error when attempting a UDP Multicast in the typical 'example' method way. (Error 59 when attempting to open the multicast port)

Because there are TWO ethernet adapters in the SOM 9651 you HAVE to specific WHICH ethernet adapter you wish to route the UDP to. Otherwise, you will get an error if the other ethernet port is unused.

This is not made clear and is only an issue when more than one ethernet adapter is present.

Jack,

The detailed help for UDP Multicast Open states that specifying an address is useful if you have more than one network card. I imagine this is the same behavior seen on other cRIOs and even on PCs.

You may get more traction on this type of question on the LabVIEW Real-Time discussion forums since it isn't particular to SOM or sbRIO hardware.

Thanks,

Bryan
