GPIB Instrument not found by VI (but seen in MAX)

Hi there
 
i got following problem:
i developed an app with LV7.1 under WinXP. i got two GPIB instruments in my system, and all works fine. when creating an executable and running it under Win2000 i see and am able to communicate with the controller and both instruments in MAX, but my VIs see only one of the instruments, the other one returns Error BFFF0011 ("Insufficient address information or Instrument not found").
 
anyone got an idea?
 
thx in advance
chris
Best regards

chrisger,

maybe I did not get your problem, but ...
Why don't you define virtual instrument names (e.g. 'Analyzer' and 'Controller') and use these to communicate? This way MAX is taking control to 'resolve' the adresses, which leaves your VI unchanged whenever you have to change the physical adress of any of those devices.

Just my Euro 0.02!

hello lul,

i'm using the "VISA resource name" selector on my frontpanel to select the desired device at runtime. The selector lists all devices by their address like "GPIB:12:INSTR", and as long as the addresses are bound to the instruments they should be shown in any case. the fact is that one of the addresses isn't shown at all, so i can't link the address to a alias name.

well, after some struggling i compared the VISA - Versions on both systems. the develop-system got 3.2, the execution system 3.1. i upgraded both systems to 3.3.1, and guess what? all works fine now...

thx and best regards
chris
