Error 10800 in digital "Buffer Read" block

[mingalls]

I have a routine that is collecting data, but when I use the buffer
read block, no data comes out. I know that there is information in
there (and that the program can access it) because the backlog value
increases as the program runs. Has anyone else experienced this
problem before? If so, what was causing this to happen?

I don't know if this might have something to do with it, but I am
running a routine that calls a subVI through an "Invoke node." It is
with this subVI that the "buffer read" block tries to access the
data.

Thank you for any help or insight you can provide!

Michelle,

You are getting a timeout error. We have some information on this available on the web:

I'm not sure whether your use of an invoke node would cause this error. I would suggest making the simplest VI possible to test the aquisition code and get it working before using it with an invoke node.
