I have created a Labview program to control the USB-7856 FPGA device on a PC and converted it to an executable file. I have verified that this executable file works fine on this PC. However, when I used this program on another PC, the RIO I/O controls on the front panel stopped responding. The down arrow button on the right side is grayed out, and when I click it the list of RIO devices does not appear. If anyone knows the cause of this problem, please let me know. Attached is the screen shot of the grayed out control.
Solved! Go to Solution.
Does your deployment PC have the NI-R Series RIO driver installed?
Is your USB-7856 detected in NI MAX on the deployment PC?
Thank you for the reply.
Yes, my device is recognized as "RIO0" in NI-MAX.
Also, I installed the NI-R Series RIO driver as attached.
First, I installed the latest version (ver.2023) but it didn't work.
Then, I tried (installed) ver.21.3 after uninstalling ver.2023.
Wow. That is the most chaotic installation of LabVIEW I have ever seen! You appear to have one version of LabVIEW (2019), 13 (!) versions of LabVIEW Runtime (from 8.5.1 to multiple copies of LabVIEW 2023 (and both 32-bit and 64-bit), three components of DAQmx (all 2019), VISA (and VISA Runtime) 2023 Q3, ...
Here's my suggestion. Try this on a PC without LabVIEW (or on a VM without LabVIEW) or on a PC where you don't mind completely uninstalling LabVIEW (I'd advise not doing this right away on your Production machine).
Thank you for your suggestion.
I agree that my installation is terrible.
I cannot stop the experiment we are conducting now,
so I will follow your instructions when it is over.
I think it will fix the issue.
