In fact it does but it's not easy to find, see here. And at the very bottom of the page, they give a trial code. To answer your question, I haven't tried. Hope this helps

AFAIK, there's no such thing as an 'NI supported mass flow controller'. Sensors and instrumentation come from literally thousands of different vendors, with nearly an equal number of protocols, interface architectures, etc. If you're talking about stuff that ultimately wires up as 0-10V, 4-20mA, thermocouple, or digital I/O, there are plenty of hardware solutions from NI which span two orders of cost magnitude depending on channel count, conversion rate, resolution, and such. If it's a garden-variety scope, DMM, power supply, RF voltmeter, spectrum analyzer, etc. from one of dozens of major vendors, and it talks serial, IEEE-488, or Ethernet, probably somebody has already written a set of VIs for communicating with it (ranging in quality from excellent to atrocious). When you get to the more specialty use analytical or process control devices, you may a) luck out and find a vendor with a great package of VIs to control their device (rare in my experience), b) get some half-a$$ed attempt at a LV driver written by a summer intern the vendor had five years ago (far more common), c) feel lucky just to get a protocol document the vendor publishes and start coding your own (my personal favorite), or d) find out that it's your lucky day - somebody on LAVA or Info-LabVIEW has used this instrument and will send you some working code that gets you up and running in a day. So, is this an 1179A series MFC with the RS-485 serial option? 'Cause if it is, you get option (d). Let me know, Dave
