Solution
This behavior may be expected depending on the bitness of LabVIEW and LabVIEW Real Time Module you are using. Some Real-Time targets like CompactRIOs are supported on LabVIEW 64-bit only after the CompactRIO 2022 Q4 driver release.
LabVIEW 2020 or Previous Versions
Prior to the 2021 release, the LabVIEW Real-Time Module was only available for 32-bit development environments, and therefore could only be used with LabVIEW 32-bit. Software requirements of CompactRIO driver include the LabVIEW Real-Time Module.
Because of this, viewing any Real-Time targets is not possible with 64-bit LabVIEW.
LabVIEW 2021 or Later Versions
LabVIEW Real-Time Module 64-bit is available as of version 2021, however, it only supports the following subset of the Real-Time hardware:
- Real-Time Desktop
- Real-Time FlexRIO
- Real-Time PXI
In summary, to enable support of Real-Time hardware like CompactRIO, ensure you are using 32-bit versions of the development environment. To be able to use 64-bit versions of LabVIEW and LabVIEW Real-Time with CompactRIOs, you must install CompactRIO 2022 Q4 driver and a LabVIEW development environment version compatible with it.
