It seems that no matter the virtual port I am using, it does not work. Could you have a look at my sample.vi, I know it's poorly wired, especially since I'm more in .NET things than NI from my occupation ^^'. I also provided a dummy DBC file to simulate a very basic input.
And by the way is there any way then to get the Byte Array / Bit Array corresponding to a certain message (and how to set the signal values required to get the message)?
