If you set up a change detection event as so:
There isn't anything in the event data node to tell you which line triggered the interrupt. I'm proposing we add something in the event data node for this event (like a bit field or a reference to the channel) so the programmer would know which line fired the event.
The workaround is you do a DAQmx read at this point and you mask the data vs previous data.. but I would prefer not to do this.
