Hello,
The manual says the following about communications connections:
Communications Connections
A HART communicating device, such as a Model 375 Field Communicator or a personal computer running AMS ValveLink Software communicating through a HART modem, interfaces with the DVC2000 Series digital valve controller. You can connect at any point on the 4−20 mA loop. Alternatively, convenient termination points are located on the termination board (figure 2-13). The instrument must be powered before digital communication will commence.
So you'll need to work out how the AMS ValveLinkSoftware communicates through that HART modem. The best thing to do would probably be to contact the manufacturer of the device, and ask them how/if it can be controlled from 3rd party software. You'll need either a DLL driver or a set of commands that can be sent through the HART modem to the device from possibly? the computer's serial port. I do not know anything about HART modems. I believe that this some kind of tranfer protocol rather than a manufacturer - so I guess that it converts something like a serial string to a set of commands that the device understands.
However this is all guess work - the best thing would be to talk to the manufacturer and find out the different ways of communicating with the device from a computer. Once you have this information - post back/start a new thread asking how to interface these methods from LabVIEW.
Sorry I cannot be of more help
