NI-DAQmx 2024 property nodes

[Wizzo_RFE]

Hello everyone,

I'm running into a quite infuriating issue with DAQmx. We're slowly stepping over from LabVIEW 2015/2018 to 2024 Q3. I've been tasked with upgrading one of the projects to this newer LabVIEW version.

Everything seems to have compiled smoothly by use of the Mass Compile tool, but for some reason one of our classes which uses DAQmx is unable to run due to problems with 'DAQmx Event' property nodes. In the previous version this worked fine, but in 2024 Q3 there are no selectable properties.

Is this a change since one of the more recent LabVIEW versions, or am I missing something?

I've attached all DAQmx drivers that have been installed, and two screenshots of examples that work fine in LabVIEW 2015, but no longer work in 2024.

I've also tried Googling but came to no results, only 'download DAQmx'. ChatGPT keeps mentioning DAQmx ADE Support, but I can't find it in any of the DAQmx packages.

Does anyone know what happened here?

Thanks in advance!

It looks like you can just replace the property node with the correct ones. DAQmx Event is not a legit type (to my knowledge). But the settings you are looking for are available in other types of property nodes for DAQmx.

Thanks for the swift response ShockHouse.

Before I left the office yesterday I did a double check with the LV2015 project and noticed that the property nodes in said project were indeed linked to Timing and Channel classes.

I think the problem is solved now by simply assigning the Channel and Timing classes to the problematic DAQmx Events propertynodes as the VIs are now runnable again. The only thing I did notice is that I can't select the properties that are part of the already placed property nodes.

See the attached images.

Do you have an idea why that might be?

Is there maybe a filter selected for the properties?
