Hi,
It's not possible to determine exactly which function is involved,
because many functions can handle a part of this module. Even if we
find the function, the fix will only be applied on the next version of
LabVIEW, and not on the 6.1. I think, the best way for you, if you

Hello,
I have looked into your vi. You are using the function AO C-GEN, I
believe that this is taking up the time. The Ao C-GEN is a higher
level. What you need to use is lower level functions such as AO
Config, AO Write etc. If you expand the AO C-Gen.vi then you will see
the lower level vis in
