Monitoring temperature from NI real-time

[jruhland]

I found this document which describes how to read data from the sbRIO-9651's internal temperature sensors and I have tested out the example VI.

It it possible to access this data through the linux file sysem or somehow read it from a C program running in NI real-time?

jruhland,

LabVIEW is able to read the sbRIO's internal temperature through a component known as NI System Configuration API. It may be possible to call into this API in a C program. We're taking a look at the feasability of this now and will keep you updated with our progress.

Thanks,

Sorry for the delay,  I was looking into this in parallel.  I confirmed the answer on Friday, but didn't get a chance to post.

The system configuration functions do have a C API.  That API is documented here: 

NI System Configuration Functions

Thanks for the help, I abandoned my previous plan of creating a shared C library from a vi and used the SysCfg API instead.

I've attached the module's source as reference in case anyone else is interested in doing this in the future.
