Tom,
Actually, thanks to Pressure Systems doing the leg work, controlling and reading data from Netscanners into LabVIEW is very easy. First, download the LabVIEW drivers from their website:
http://www.pressuresystems.com/Portals/11/SoftwareFirmware/NetScanner/netlab.zip
Once you've extracted the .exe, run it and save the files to a directory you can access easily. Then extract the PSI9016.llb from the file 'newlvvis.zip'.
Then you can write a very simple application to initialize, rezero, and read from the modules, much the same as you would do buffered acquisition with NI DAQ boards. One thing I've learned from using these VIs over the years - don't directly wire the TCP address out from the initialize routine directly in to the subsequent VIs. Instead, create an indicator of the address, then use Local Variables reads to send the address into the Rezero, Read, and Close VIs. Finally, the Rezero routine assumes that you have a 100-120 PSIg dry gas (air or nitrogen) connected to the 'SUPPLY' port on the Netscanner. This allows a pressure-activated solenoid to actuate which puts equal pressure on both sides of the diaphragms of all the transducers. Skipping this step can lead to offset data!
Good Luck,
Jim
