Jim C Posted October 29, 2010 Report Share Posted October 29, 2010 I want to read the Current State, Remaining States and Arguments indicators from the FP of the Parse State Queue vi in my JKI State Machine. I can't figure out how to get a reference to the VI. Can you help? I've looked and it doesn't appear to be in the App.All VIs In Memory list. I tried to modify the VI to return a reference to itself. No luck. I can see all instances of it when I set the FP to show when called, but I have some JKI-SM processes that I'm not interested in. Alternately, can you suggest how I can monitor this information? Link to comment Share on other sites More sharing options...
Jim Kring Posted November 8, 2010 Report Share Posted November 8, 2010 Hi Jim, I'm really sorry for the long delay in response. You asked a relatively non-trivial question, so it wasn't one that could be answered quickly. Here are my thoughts: Parse State Queue is reentrant, and LabVIEW doesn't provide a super-easy way to get the references to instances (a.k.a "clones") of reentrant VIs. I think what you would need to do is get a VI reference to the VI that contains the JKI State Machine, and then traverse its block diagram for GObjects of type "subVI" (using "vi.lib\Utility\traverseref.llb\Traverse for GObjects.vi" -- see here for tips from Darren). You would can then get the instance/clone VI reference from the subVI reference, check if it's VI.Name is Parse State Queue and then get it's Front Panel control references. Whew... that was a mouthful Let me know if you have any questions about this. I'm happy to help. Thanks, Link to comment Share on other sites More sharing options...
Jim C Posted April 13, 2011 Author Report Share Posted April 13, 2011 Thanks for answering. I did this (snippet) but it didn't work. I don't get any errors, it finds the SubVI and I can even open the Front Panel but the reference isn't to the one This VI is using. The Get Control Value nodes don't show anything. Did I misunderstand your intent or is there more to this? Jim Link to comment Share on other sites More sharing options...
