Hi, See the links below : - http://exchange.ni.com/servlet/ProcessRequest?RHIVEID=101&RPAGEID=135&HOID=506500000008000000F3A60000&UCATEGORY_0=_49_%24_6_&UCATEGORY_S=0 - http://digital.ni.com/public.nsf/3efedde4322fef19862567740067f3cc/75bf35eb4afb834f862566210065fa61?OpenDocument - 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 ! Julien
