  • PXI Controller

Issue Details

I know that National Instruments sells controllers with the LabVIEW Real-Time Engine installed on them as an operating system, but I have an existing PXI controller with a Windows operating system on it. Do I need to purchase a run-time license in order to install the LabVIEW Real-Time Engine on my controller?


For Phar lap ETS

Yes. If you want to install the Real-Time Engine on a Windows based PXI or desktop PC then a run-time deployment license(PN 777849-01) must be purchased.

Note: NI will remove support for PharLap for cRIO in the NI 2020 Software Release and for PXI in the NI 2022 Software Release. For more information, please see the PharLap RT OS EOL Road Map.

For NI Linux Real-Time

No, deployment licenses for Linux RT will be no-cost. To install the Linux OS on the PXI controller, you could refer to this link. Provisioning a PXIe Controller to the NI Linux Real-Time Operating System
