Autotuing PID's on cRIO

[sakalaukus]

I'm using a cRIO-9074, and I have a few PID's I'm running on the real time processor, not the FPGA.  I was trying to use the autotune PID, and I get a 1013 error, Labview cannot load front panel for the autotuing PID wizard.  Is it possible to use the autotune PID wizard with my hardware?  If so, what do I need to change to use it?

Hello Sakalaukus,

Thank you for contacting National Instruments! I have looked into the error that you are receiving and I believe I understand why you are getting this error.  This is because the Real Time Controller does not support front panel properties and methods:

When you deploy a VI down to a Real Time Controller it is as if the block diagram runs on the Controller and the front panel runs on your Host Machine.  There is communication between the Host machine and your Controller in order to update the front panel.  However, a front panel cannot run on a RT controller and therefore programmatically opening a front panel on the Controller will yield the error that you are receiving.

Here is some documentation regarding the autotune PID Wizard:

If you have any further questions please just post them here.  I hope this helps!  Have a great day!
