The image I attached in an earlier post shows the VIs in my Utilities pallet.  My list of VIs appears to be incomplete based on that link you posted.

"Real-Time Module. This topic might not match its corresponding palette in LabVIEW depending on your operating system, licensed product(s), and target."

Is your RealTime version up-to-date?

So... I contacted NI Support.  Turns out, in order to see all RT VIs, you must be programming a VI under the RT target in the Project Explorer.  So, for future reference kiddos... learn from my mistake.  Right click Project; New; Targets and Devices; New Target or Device (assuming there is no existing target); Expand Real-Time CompactRIO; Select appropriate type.  Now make VIs under the target and all VIs will become available in the Pallette.

haha, gosh I could have told you that. The compiler doesn't know what target you're on otherwise and the palettes change to match the target. Good stuff.

Hey there, so with initial tests, the Memory VI available for RT doesn't appear to be the type of Memory I was thinking.  I made a very simple test.  I created a constant timed loop to measure the memory while writing to an indexed tunnel.  The idea, as the tunnel increases in data, it should allocate more memory.  I did not see any changes in the memory.  Is this VI not necessarily what I thought it was?  Just simply how much space is left on the target for more code?

From what I know, you can't view the buffer memory statistics on the cRIO. This seems to point to the System Manager being able to show you, but that's the only place I can find what it sounds like you're looking for.

RT Get CPU Loads can show you a bit of statistics regarding how bogged down your RT target is, but not the memory usage.
