Data acquisition using cRIO-9066 and C++

[aanodin]

Hi there!

I want to write a C++ application which would acquire data from some modules installed in cRIO-9066 chassis and this application have to work without LabView. How can I do it? Can I connect this chassis to my PC using NI DAQmx? Is it possible?

Hello aanodin!

cRIOs are not compatible with NI-DAQmx because they don't use the same data acquisition process as our DAQ devices. They would instead use the LabVIEW Real-Time Module and the NI-RIO driver. Since the cRIO-9066 controller's operating system is Linux Real-Time, you can deploy your C++ code directly to your target using the C/C++ Development Tools for NI Linux Real-Time, Eclipse Edition.  I would recommend reading the following articles:

I hope this helps!

Thank you, Queen_Nadine!

Does it mean that I can only run my C code on the device and there is no way to acquire any measurement data on the host computer without LabView?

You could use TCP/IP to stream the data to a Windows computer and have that computer log the data or do whatever else you need.

But you might want to just get a cDAQ Chassis instead and then you can just use the DAQmx API.
