Issue Details

I heard that some cDAQs have controllers with real-time operating systems like Linux Real-Time (Linux RT). I am having timing consistency issues while using a computer with a PCI card to control the data acquisition and am interested in moving to a real-time operating system. If I have an existing program that is running on my computer, can I easily switch to a cDAQ with a controller?

Solution

If switching to a cDAQ controller that runs Linux Real-Time (Linux RT), the program would have to be created with LabVIEW Real-Time Module. However, cDAQ controllers allow use of the NI-DAQmx driver and functions with the LabVIEW Real-Time Module or LabWindows/CVI Real-Time Module, which would make transferring data acquisition tasks from existing DAQmx programs relatively straightforward.
