Hi All,
Recently, I found that auto indexing variant array is the cause of high CPU jump in LV2011. CPU jumps even if you call execute variant indexing once, stays at high CPU level and never goes back.
I created a test project to demonstrate it, in my case it happans on cRIO-9014, 1925 controllers in LV2011. We found high CPU issue after LV8.6 to LV2011 project conversion and found the cause that I want to share.
NI is working on this issue.
To resolve the issue, instead of using variant auto index in the While, For, Timed Loops use Index Array function. After the replacement the CPU level in our projects dropped in 20% on cRIO-9014 and in 60% on cRIO-9025
