LV 20.0.1 and cRio 9074/9075

[moonrec]

Greetings. We recently upgraded from LV2017 to LV2020. We have a distributed DSC monitoring system based on four cRio 9074 and a cRio 9075. To my surprise, the system says that my units are not supported by the system. that the last supported NI Rio for these units was version 19.6. Is there anything we can do to make this hardware work short of replacing all the modules? We did the upgrade in order to stay up tp date.

Easiest is to downgrade to 19.6 and lock it in forever or buy new HW that is supported by the latest drivers.

The cRIO 907x chassis are VxWorks based controllers. NI has announced the removal of support for VxWorks from all software releases after version 19.6 about 2 years in advance. Unfortunately it seems impossible to find that announcement anymore anywhere.

In the same way all Phar Lap based cRIO controllers were EOLed for the release of software version 2020 Q2 and newer. PXI RIO support for Phar Lap was completely removed this year.

There are only two options:

1) upgrading to Linux RT cRIO controller

2) freezing your development platform on LabVIEW 2019 SP1 and CompactRIO 19.6.

Thanks for the information! I never received those emails and I don't lurk at the NI site frequently. Last email from NI was on January for a webinar and before that on 2016 when I renovated the service. 2017 seems to run good on the Win11 development machine so I will not update my severs where the datalogging is running. I have 5 cRio running here, so I need to plan for the replacement. As for the LV 2020 software, well I have now a ticket to find out what is going on with the DSC installation issues.

Greetings,

Is it possible to run cRio 19.6 on the 2020 environment? That would give me more time to work out the HW replacement issue. By the way, LV 2017 seems to work good on the Win 11 machine, but I was afraid it would encounter some problems after updates to Win 11 and I did not wanted my data collection stopped for some Win issues. 

Thanks!

Is it possible? Yes sort of. Is it supported? No absolutely not.

The NI drivers only support LabVIEW and other application software of the same version and 3 previous versions. The driver installer explicitly will NOT install into application software that was not released at the time the driver was released.

In theory you could investigate what files are installed and then copy them all over into a newer LabVIEW version. In practise this is a very time consuming, error prone and temporary useful effort. You would have to do that with every new version again, and there is no guarantee that there are actually no binary incompatible changes that such a manual update would miss and then crash your system when you try to use it.

NI is planning to change this with the new drivers that will be released in fall of this year, where the driver version is not tightly tied to application versions anymore. For your case this is however useless, as that will be only relevant for driver versions 22.5 and beyond.
