needed software packages on cRIO for Multicast UDP

[GerdW]

Hi,

I would like to execute that snippet on a cRIO system:

(open a port for multicast UDP messages).

On a standard Win7 PC it's working, I can send and receive messages with no problem.

But on a cRIO I get an error 54 ("wrong network address"). So what the heck?

The cRIO is set up with those software packages (LV2011SP1):

I want to reduce memory consumption, so didn't choose to install all recommended packages.

I suspect something is missing. Which package part is it?

I found a solution (or is it a work-around?)...

You have to wire the "network address" input of the UDP-Open function. It seems the cRIO doesn't know it's own IP address:

One more correction: You only must use "String to IP" on the cRIO. When used like shown above it gives error 54 on the PC! Arrrgghhh...

Next solution: Put the StringToIP node inside the ConditionalDiagramDisable structure already in use 🙂
