VI Error question

[sean_tan]

I found that VI Error in many CVI drives.but there is a question about VI Error:

wha t's mean of
"BFFC0001 Parameter 1 out of range, or error trying to set it."

what's "parameter 1 or parameter 2 and so on " .

That is an IVI or LabVIEW error with identical meanings. The function you are calling has parameters and there is a problem with the first parameter you are setting. It would really help if you tried to explain where and how you are getting this error.
