"Cannot use a variable node of this type on this target"

[Doogie2K]

Alright, I just upgraded to LV-RT 8.0 and a PCI-7041/6040E.  I tried creating a sample RT project, just to see how it works.  The "target" VI, however, has a broken arrow, and is "not in a deployable state": all the shared variable nodes that LabVIEW automatically creates (as well as any I try to make myself) are "illegal" because I "cannot use a Variable Node of this type on this target."  Why?  After hours in the Support pages, and various different configurations of RT project, I have yet to find any sort of indication of what the restrictions are on Variable Nodes, and how they at all relate to the type of RT target I'm using.  Certainly, one would think that the program-generated VIs would work, no assembly required.  I already know that you have to manually install bootup software on the 7041, instead of it coming pre-configured to be simply inserted and used; what other post-installation setup is required in order to be able to actually make use of Variable Nodes?

OS: Windows XP

You are probably getting that message for one of two reasons:

1) You are trying to use network-published variables.  They aren't supported on the PCI-7041.
2) You are using a single-process variable, but the VI you are referencing it from is under a different target than the variable.

Alright, problem solved now.  You basically can't have a host VI in a 7041 project.  That can be worked around, I think.
