system identification error 41263

[ajaleelp]

hi...

can somebody please explain why i am getting an error "41263-The System Identification Toolkit cannot retrieve the data in system model because the model type you wire in is incompatible with the system model requirements. " while using model simulation vi to simulate an arx model i created using estimate arx model vi?

Hi ajaleelp,

Sorry for the delayed response on this, but I have a few questions for you.  Are you just receiving this error at run-time? Meaning you have no broken wires or anything, but the VI stopsat the model simulation VI?

Also, have you tried our example for model simulation? You can find it here:

C\program files\national instruments\labview [version]\examples\System Identification\Getting Started\General.llb 

This actually uses the estimate arx and model simulation VIs. So, you should be able to see if that works, and then compare it to your system.

Hope this helps!
