Problem with RTEXE file on PXI

[Herlag]

I've attached the BD image of a very simple code which illustrates a problem encountered with a RTEXE file on PXI.

If the VI (LabVIEW 2011) is launched on the RT target from a LabVIEW project, no problem.

If the code (with the shared variable linked to a I32 indicator typedef, the ctl and lvlib files being on the target) is compiled and run as startup from my PXI system, it doesn't work (message = "incorrect state" or something equivalent in french) !

But when the shared variable is disconnected from the typedef, the RTEXE file runs correctly as startup...

Any explanation for this strange behaviour ?

Any way to run a RTEXE file on a PXI controller with shared variables linked to typedefs ?

Thanx & BR,

Hi there,

A screenshot of the error encountered would be helpful, even if it's in french, could you make it for us?

Hi,

Here are 3 screenshots :

Loops_1.png : Code running on the PXI target from a LabVIEW (2011) project.

Loops_2.png : RTEXE compiled code NOT running as startup when the shared variable is linked to the typedef.

Loops_3.png : RTEXE compiled code running as startup when the shared variable is NOT linked to the typedef.

HI HL,

Thanks for your screenshots !

You have compiled your "RTEXE" but first of all, have you deployed your shared variable before running the exe?

In both cases (when the shared variable is linked or not to the typedef) I have to reboot the PXI controller to run the Real-Time executable. As it works in one case, I assume that the shared variable is automatically deployed when the controller restarts. Otherwise, how is it possible to deploy it before launching the RTEXE as startup? Or is there a special compilation option to do this?

BR,

I've made the same tests on a cRIO target under LabVIEW 2012 : everything is ok.

Any reason why it doesn't work on a PXI under LabVIEW2011?

I've got an answer on the french section of the forum : it's a bug of LabView2011, corrected in LabVIEW2012.

The only solution with LabVIEW2011 is to disconnect the shared variable from the typedef 😞

Hi HL,

Sorry for the late reply, I was unable to receive the update from your post... but glad you find out your answer !
