how to choose CRIO

[Risuraj]

what is the major specification differentiate CRIO 9035,9045 & 9047.which one will give flexible programming support.

Just looking at the quick specifications, I see the cRIO-9045 has more RAM than the cRIO-9035.  Everything else is basically the same.  But the cRIO-904x series added support for DAQmx on the RT instead of being forced to write your own FPGA or the Scan Engine.  Then the cRIO-9047 is a pretty major upgrade over the cRIO-9045 (double the RAM, faster processor clock, more processor cores, wider temperature range).  But is the $1.6k worth it for your application?

So based on the applications I have done, I would lean to using the cRIO-9045.
