Dynamically open "Control Design and Simulation" VI on LabView RT

[pgraebel]

I am successfully opening VIs at runtime on a LabView RT system via "Open VI Reference". Usually these VIs contains various VIs from the standard palettes, like RT-FIFO. I am building LLBs that contain the main VI and my custom-made SubVIs.

But as soon as I am adding "Control Design and Simulation" VIs (e. g. integrator) to the dynamically loaded VIs, I get bombed with 1003 errors.

Workaround at the moment is to include the "vi.lib" in the LLB. But this leads to a huge filesize (16 MB or bigger), it's highly redundant and the build process takes a lot of time.

The "Control Design and Simulation" module is already installed on the RT system. Why are the simulation VIs not found there but other standard VIs (like RT-FIFO) are found?

Hi

Problem is not all VIs are installed with the driver package or other distributions on the Real-Time target.

That means not all the VIs installed on your computer are also available on the Real-Time target.

So you have to either always inlcude the missing VIs or building a source distribution. Please have a look at the following KBs:

Error 1003 or 1124 When Using VI Server To Call a VI on a Real-Time Target

Error 1003 When Using VI Server in a LabVIEW Application

Hope that helps.

Kind regards
