labview error

[QILANADIA]

Hello hi everyone,

I just update NI MAX 16.0 to NI MAX 20.0.

Then, i run a labview project and i enter a value to change vfd speed, suddenly an error popup on my desktop screen stated that "An input parameter is invalid.....

I'm using labview 13.0f2, ni daqmx driver version 16.0.1. 

Herewith I also attach my NI MAX and error for your reference.

I'm not sure which part went wrong because before the update, everything was normal, no error at all.

I'm suspecting the driver update is not compatible with lower version of ni daqmx or maybe i missed something else.

Anyone can help me resolve this issue?

Thanks in advance.

Thanks in advance

Why did you  do that? Why change a running system?

DAQmx16 does support LV2013, as it's the "current version and 3 older versions before" range.

The error you show is a runtime error, involving queue functions: this is not related to DAQmx at all. If it would be a problem of unsopported DAQmx version then your "LabVIEW project" would not even be runnable…

Hi Gerd,

Thank you for your reply.

I decided to change/upgrade the NI MAX because last week my NI CDAQ 9178 and its module were not detected in NI MAX. Thus my project cannot be run at all. 

Before I update the system, I read on NI website, higher version of NI MAX will support lower version of LABVIEW. I thought that would not be the problem because after the update, all modules are detected in NI system.

So, the next step should i downgrade my NI MAX? 

"The error you show is a runtime error, involving queue functions:" is this have anything to do with my programming or my instrument wiring?

Thank you.
