PID advanced autotuning VI on FPGA

[JensBaetens]

Hi,

On the website of NI, explaining the PID advanced autotuning, it says you can use this VI on an FPGA target.

( http://zone.ni.com/reference/en-XX/help/370401H-01/lvpid/pid_advanced_autotuning)

"Implements a PID controller using a PID algorithm with advanced optional features, and applies autotuning to the controller. You can use this VI in RT and FPGA applications."

When trying to use this PID on an FPGA, the following errors occur on different subVI's of the PID controller.

"type not supported in current target"

So, can the PID controller be used on an FPGA?

Hope to get some answers 🙂

Hi Jens,

I think this is a bug in that old version of the LabVIEW help. (FPGA doesn't support DBL datatype!)

Just read the current version…

That's what I was thinking 🙂

Didn't notice I was using an old version of the LabView Help!

Thanks for the fast response
