VI Server from RT PXI

Question

Is it not possible for a VI running on an RT target to call a VI running on the Host PC?
To wit: I can run this VI Server example with emb.llb on my RT target's hard drive and "call emb.vi" running on my Host PC.  I want to be able to do this the other way around.
Attempting to do so results in a message stating that "Error 66 occurred at Open Application Reference in call emb.vi" approximately ten seconds after call emb.vi starts executing.  I have already enabled machine access in the project (I am using LV8.2) through the properties pages of My Computer and the RT PXI Target, as well as in the Tools->Options dialog.
Am I attempting to do the impossible?

Answer 1

By changing the path constants to string constants I was referring to the green path constants to pink sting constants in "call emb.vi" which had values of fglobal1.vi and fglobal2.vi. The reason is stated in the help here. "If you wire a name string, the string must match the full delimited name of a VI in memory on that target. If you wire a path, LabVIEW searches for a VI in memory that you previously loaded from that path on the same target. If a matching VI is not found in memory, LabVIEW then tries to load the VI from that file on disk." So if a VI is already loaded in memory you can simply access it using the VI name as a string. If you use a path, you must use the full path and it will first check to see if a VI is loaded in memory with that name from that path, and if not then it will load it from disk. The example you were looking at does both.
I've thrown together a simple example showing both calling a VI from disk and from memory. I've included the project for it so all of the VI server settings should be carried along with that and it should just work. All you have to do is copy/ftp the "Get Info.vi" to "c:\ni-rt\startup" on both the Host PC and the RT Target and then you can experiment with different combinations.
