PXI Modules Found in Max But Cannot Locate in LabVIEW

[ebs27]

Hi,

I have the following hw/sw configuration

Chassis: PXIe-1082

Controller: PXIe-8101 (PharLap OS, BIOS 13.1)

Modules: PXIe-6361, PXIe-6124, PXIe-6124, PXI-4110, PXI-5402, PXI-7854R

The PXIe modules are plugged into PXIe slots while the PXI modules are plugged into PXI Hybrid slots

Win10 with LabVIEW 2021 SP1 and DAQmx 21.3, FGEN 21.3, DCPOWER 21.5, VISA 21.5, NI-RIO 21.0.

Issue:

All of the devices are present in NI MAX and successfully self-test. I can also locate all of the devices through a VISA resource. I am able to use the PXIe DAQmx devices successfully. However, I am not able to use or locate the PXI-4110, PXI-5402, or PXI-7854R devices in LabVIEW. I've tried opening up FGEN and DCPower examples, but the devices are not found in the device controls. I do also get a green ACCESS LED on the 5402 module, so it seems everything is present and connected.

I checked the Readmes for the driver versions and it appears my version of the FGEN and DCPOWER drivers support my cards. I did look to see that the R Device is NOT supported by this RIO version, so that would explain why I cannot find it as a Target.

At the moment, I am stumped! I also haven't worked much with PXI, so it's possible I just have something configured incorrectly. I have confirmed the drivers are installed on both my PC and the PXI system

Many thanks!

Is your VI running under My Computer or Remote Target in LabVIEW?

I’ve tried both! Only the PXIe modules are all present when the VI is running under the target in the project.

Update:

I have the PXI-7854R device working-- turns out it required the CompactRIO Driver (21.0 for my version) and the R Series Multifunction support to be installed on the host and the PXI

The DCPOWER (PXI-4110) and FGEN (5402) devices are still not working. I noticed I had DCPower 21.5 on the PXI, while 21.3 was on my host PC. I downgraded everything to 21.3, but that hasn't solved the issue.

Doh! I figured out what I was doing wrong.

I checked the bug documentation for the DC Power driver version and it says that the device will not be detected in a resource control/constant and that you will need to enter the device's name from MAX manually. Once I did this, it worked (with VI running under remote target)! The same thing applies for the FGEN Driver/PXI-5402 device. Curiously, it says this is fixed in LabVIEW 2021, but that was the version I was using.

Anyways...all I had to do was check the documentation more thoroughly!
