LabVIEW Real-Time Module Platforms (RT Module)
National Instruments designed the LabVIEW Real-Time Module to execute VIs on three different real-time platforms. The Real-Time Module can execute VIs on hardware targets running the real-time operating system (RTOS) of the Ardence Phar Lap Embedded Tool Suite (ETS) or Wind River VxWorks, and on computers running the Ardence Real-Time Extension (RTX).
Ardence Phar Lap ETS and Wind River VxWorks provide an RTOS that runs on NI RT Series hardware to meet the requirements of applications that need to behave deterministically or have extended reliability requirements.
Ardence RTX adds a real-time subsystem, called an RTX subsytem, to Windows under which you can execute LabVIEW VIs or applications. Ardence RTX enables you to run Windows and the RTX subsytem at the same time on the same computer. The RTX subsytem has a priority based real-time execution system independent of the Windows scheduler. RTX subsytem scheduling supersedes Windows scheduling to ensure deterministic real-time performance of applications running in the RTX subsytem. Refer to the Ardence Web site for more information about Phar Lap ETS or RTX. Refer to the Wind River Web site for more information about VxWorks. Refer to the LabVIEW Real-Time Module Release and Upgrade Notes for installation instructions.
The Real-Time Module platforms do not support some LabVIEW features for VIs that run on ETS, VxWorks, and RTX targets.
