Hi Daniel,
If you know the command set of your instrument, you can try communication using the VISA API. You probably have NI-VISA installed already since it is required for most of the instrument drivers on our web page. If you do not have it, you will need to download it from
here. Is your temperature controller a GPIB Instrument? If so, try using the example I have attached below that uses the basic VISA functionality to write a command to the instrument and read back the response. You will need LabVIEW 7.0 or higher to run it. Just put in your gpib device resource name and a known command into the VISA Write and set it to read an expected number of bytes. You should be able to read command responses directly from the instrument. If this works, you can try to build your own driver around this example. You can also try using the Instrument I/O Assistant Express VI which often allows for instrument communication without instrument drivers. This can be found on the Express palette on the block diagram in LabVIEW. I also suggest going to
www.ni.com/idnet and selecting "Request Instrument Drivers" to put in a request to our driver development team. These are considered when developing new drivers for future releases.
I hope this works for you, but if you have any questions, please let me know!
