Reentrant VIs

dmlawrence · February 11, 2009, 7:56pm

I wrote a traction control VI that I made reentrant. This VI is placed on the block diagram of another VI in two locations. It is my understanding that I should be able to open two front panels of the reentrant VI - specifically, one for each block diagram instance. However, I can only open a single instance of the front panel, which is not linked to EITHER of the VI instances on the block diagram. (I don’t know if it matters, but the reentrant VI is located in a while loop.) How can I get to the other front panels?

thanks,
David

Thanks very much… that’s not exactly the solution I was hoping for, but we’ll make it work.

Yep. That feature isn’t fully supported in RT. A workaround would of course be to open the VI and save two versions under two names. Make them not be reentrant and now you can debug. You then of course need to be careful if you need to make edits. Once debugged, put it back to reentrant.
