I have a VI that initializes two counters using the DAQmx drivers, waits in a while loop until the exit button is pressed, and then shuts them down. I would like to alter the timing of these pulses which I can do just fine in a test VI, however when I use this as a sub VI in my main program I need to refference the DAQmx event. I can't figure out how to get this refference to my main VI so I can call a propertiy node. Does anyone know how to refference a DAQmx event outside of the VI it's created in? The only solution I have is use two VIs and outout the event refference from the first so the main can use it.
Hardware: PCI_6023E
DAQ_Test_Trigger_Outputs.vi works fine.
Ocean_TriggerSource.vi is the subvi in my main program.
counter.png shows where I'm calling Ocean_TriggerSourse.vi. The cluster contains the refference to the stop button.
I have an event loop in the main VI that handles any user input while the program is running, and is where I would like to alter the counter properties.
For the curious these counters are triggered on a pulse, then wait some amount of time (~1ms) before sending their own pulse that stays high for 1ms. The trigger pulse is coming every 5ms. I need to be able to exactly adjust each delay independantly while the program is running.
