For DAQ and other I/O programs I try to put all my I/O code in a mid-level
sub-VI that is setup as a case structure inside of a while loop. The while
loop is only there to allow for shif-registers to store data. The case
structure allows selections like initialize, read, write, ect. In my
initialize case I read an INI file that has a variable to let the program
know if hardware is installed and I store this in the shift register along
with other variables like Task IDs. I then use the hardware installed
variable to prevent calling of the DAQ or other I/O sub-VIs. By using case
structures I can provide dummy data instead of calling I/O sub-VIs when the
hardware installed variable is turned off. Another variable I often put in
my INI file is the device number of DAQ
boards because when I do have test
hardware in my computer it will often have a different device number than my
target computer for the application I am working on.
Hope this helps,
