Hi,
Please forgive me if I am very general in my question but that is because I am new to Labview. My situation is that I am trying to measure resistance data (from a DMM) and force data (from an Instron 5800 UTS machine) simultaneously during a compression test. The instrument controller for the 5800 is interfaced with my PC through a GPIB bus and uses its own proprietary control software. However it did come with Instron drivers and example Labview programs in order for interfacing with Labview.
Where did you get the drivers? Were they from here? There is no mention of proprietary software required. In fact, I find it quite difficult to believe that proprietary software is required. If it's a GPIB instrument it would respond to GPIB commands, and that's not proprietary.
When I run that program it stops and cannot find the vi file 'Data Acquisition Initialize.vi" and some other vi's. Is this an important file? is it NI's responsibility or is it Instron?
I think you mean when you tried to open the program. If there's a subVI missing you won't be able to run the program. That VI is not a standard VI. It sounds like a VI from the instrument driver library.
Also if I try to approach the problem the other way (not use the example prog. but make my own Labview) then I can see the Instrument as a GPIB bus in MAX but the following information is displayed ('Instrument0', 'Primary Address = 3', Description - 'This device did not respond to a *IDN? query').
This happens often, especially with older instruments. All it means is the the instrument does not implement the standard *IDN? command. Within the instrument's set of commands it's probably a different command.
