I have an OL 490 from Optronic Laboratories that I am trying to write labview code for so that I can automate it. It is connected to my computer through a USB, and it came with software that I can use to control it with ease. It also came with a software development kit, which includes a .dll file. I also have a list of the Command Set, and it has commands listed and how to use them, such as:
long ConnectToOL490()
Returns : 0 - Failed, OL490 not connected
1 - Success
I think I have to use the Call Library Function Node vi to do this. However, when I try, I always get an error:
Error 15 occurred at Call Library Function Node in Untitled 1
Possible reason(s):
LabVIEW: Resource not found.
=========================
NI-488: Serial poll byte queue overflow.
What is the deal, and what does this error mean? If I change the path of the .dll file to a different .dll file, I still get the same error, so this leads me to believe that the 'resource' that this error is referring to is the function (ie. it can't find the function in the .dll). Why would that happen?
Thanks!
