Hello again,
Due to the missing description of your problem, it was difficult to give a more precise answer ! But now, everything is clear.
See this
page.
Like mentionned in above document, the LV7 application builder will reset the constants to their default values --> 0. Add an indicator to see what's going on. In the developement environnement, the indicator will show 1, and 0 with the executable.
So you have now 2 options to avoid this :
1) Modify the labview.ini file like mentionned or
2) Right-click on the board ID constant and disconnect it from the type def. Repeat for every instance of the constant. You could also replace the c
onstant by a simple U8 constant.
Rebuild your application and enjoy that the "illegal board ID" error message has disappeared.
