Hello,
I am running a VI that controls and monitors the flow rate and pressure of gas using 2 Bronkhorst Flow Meters and Pressure gauges, which all connect to a single USB port. The VI uses predefined Bronkhorst sub-VI's and works in the expected manner. However, the program is very frequently interrupted by 1 of 4 error messages:
Error -1073807298 (Possible reason: VISA: Could not perform operation because of I/O error)
Error -1073807246 (Possible reason: VISA: The resource is valid, but VISA cannot currently access it)
Error -1073807339 (Possible reason: VISA: Timeout expired before operation completed)
Error -1073807343 (Possible reason: VISA: Insufficient location information or the device or resource is not present in the system)
All of these errors appear under similar circumstances. As noted before, the program runs fine, except for frequent pauses for error messages, and continues to run fine after pressing continue on the error message box. I have searched for solutions for each of these 4 errors individually, and none seemed to hint at the problem with my system. One solution suggested that the wrong VISA resource was chosen, which is surely not the case. Another solution suggested that another application (e.g. HyperTerminal) was competing for the same port as my devices, but the errors persist after all applications except LabView after closed. Any help is greatly appreciated. I've attached the VI for reference. Also, I am running Labview Version 10.0.1 (32-bit).
Thanks,
Patrick
