Reentrant (cloned) front panels seem not to work on PXI target

[AlexR]

Hi,

I have some problems running a reentrant VI for Monitoring on a PXI target. The VI stors some Data for the xy-Graph output and is programmed in an reentrant subVI for easy reuse purposes.

I tracked the error and stucked by the following strange behavior: I created a simple reentrant VI (file: reentrant.vi) and added this to the main vi (file: untitled-vi). If you try to double click the subVI in the block diagram you get the normal front panal of this opened. Though - it should be a cloned one! Move the untitled.vi to the "My Computer" target you receive a cloned one.

I think if this behavior can be tracked my original problem is solved as well: the front-panel of the subVIs in reentrant mode don't open properly. (Yap the options to display, when called and loaded were tried)

I'm looking forward for your response,
Alex

Hi Alex,

The reason behind that is because reentrancy works differently on the real-time system.  The VI will be running in reentrant mode but you cannot view it or troubleshoot it.

I have attached a project:  Test1.vi and Test2.vi both call the reentrant.vi. This demonstrates that the reentrant.vi works properly in reentrant mode. You will need to change the real

time target to the one you have.

I hope that helped,

Thanks Kostas,

thats all I liked to hear. I knew reentrancy works on real time but nowhere in the help was mentioned, that you will have problems with showing the front panels of these VIs.

Best wishes,
Alex
