I have a VI (LV-2017) recording the output of four identical instruments permanently that are all connected via their own USB port (virtual com port). Despite weeks of searching, one of the instruments will stop recording (seemingly randomly) and I cannot work out why, as far as I can see all of the settings are the same for all four. Either way, the only way to get it to work again is to completely exit labview, physically disconnect and reconnect the instrument and reload the VI.
Is there a way to get these instruments to reconnect while keeping the program running so I can turn one off > on (if I need to) and have it automatically re-detect? Or perhaps someone can shed some light on why such an instrument would randomly DC?
They are just connected via a standard visa resource dropdown in the VI.
Thanks in advance.
