error 10846

[Romain Monnery]

Hello I have seen your group and i 've thought that you may help me to
resolve my problem.

I have to acquire 10 AI and generate 2 AO . Each program works
perfectly alone but when i merge them the acquisition is slow and i
have the error 10846 . Even if i change the scan speed and the lenght
of the buffer i can't solve my problem . So if you have a solution
don't hesitate . i will be very happy.

- My solution : If you want to read the last 100 scans then try and use the "AI buffer read" VI and use the read/search location cluster to get that -100 scans (relative to end of data) you want. (Try and monitor the "scan backlog" output of the AI buffer read VI. This should give you an idea of the buffer's state).

Hope this helps !
