I'm running with LabView2009 on a cRIO-9074 and I get a "Manager Call Not Supported" Error at the "To More Specific Class Function" node when I attempt to typecast a cluster reference to a cluster object. This works on a PC host. Any ideas?
Thanks.

Hi meg57,
This error generally creeps up when trying to perform an operation that is not supported on a Real-Time target. I will have to do more research to see if this applies to your applications. Are you using the To More Specific Class function anywhere else in your application? If so, are you seeing any errors from them?

Hi meg57,
I apologize for the inconvenience, but it does not look like the To More Specific Class function is support in Real-Time. I have filed CAR 225899 to report this R&D.

I was wondering if there has been any progress on this front. I have some code that was originally developed to run on a PC and am trying to run it on a remote (via ethernet) RIO box with a PXI-8101 controller. The controller is running LabVIEW Real-Time 11.0.1 and the PC which I'm modifying the code on is running LabVIEW 11.0.1f2 (32-bit).
The VI contains several instances of the "To More Specific Type" operation, which does not seem to be supported by the target (I get Error Code 53 when I try to run the VI). Has this issue been resolved in a more recent update of LabVIEW Real-Time? Or do people have suggestions on a way around? Specifically, I am taking an input of type "Mixed Signal Graph (Strict)" and converting it to "Mixed Signal Graph".

Hi Zach,
I'm getting the same error with 2013 so it looks like this is still floating around as I'm getting the same error when I try this on my RT target. I would suggest posting another topic on the forum to try and find a suitable work around for the issue.

Do you have any progress on this one?

Hey after testing it with LabVIEW 2015 I'm still getting the error, so I lookup the CAR and has been flagged as a low priority, because of this denomination I'm not sure how long this matter will be dragged.

Hi, if the "To more specific function" is not working on the RT target (not supported) try using "Type Cast" in the same place.
