discrete pid express vi

[krupa]

I have to use discrete pid express vi that was there in LV2009 in my current project.In LV 2014 toolbox,it is not there.I am looking for old examples thinking it must be there.I could not find any having this tool.

Could u pls help me.

The Discrete PID VI is now an Express VI called PID (FPGA).vi that supports single and multiple channels and can be found on theProgramming»FPGA Math & Analysis»Control palette.

Ref:http://digital.ni.com/public.nsf/allkb/C1B75CF51A7136E3862573BF00757B84

Note  The PID (FPGA) Express VI is available only if you install both the PID and Fuzzy Logic Toolkit and the LabVIEW FPGA Module.

I already read this info,my concern is in the attachment you can see that the Derivative gain is disabled.Thats a Discrete PID.

The same option of disabling derivative is not available in current Express VI.PID.

if you set derivative gain =0, doesn't it become PI Controller?
-Why use only that express VI? Why not PID Advanced Autotuning VI https://zone.ni.com/reference/en-XX/help/371361L-01/lvpid/pid_advanced_autotuning/

krupa, if its possible to attach your code that would be helpful in determining why the control is grayed out.

The pic is from a docu,I am developing code with that as reference.

I did D=0,but that's ain't equal to the attachment.

Hi krupa,

all I see is a frontpanel control set to "disabled and grayed out".

Can't you do this simple operation on your frontpanel? Right-click the control -> Advanced -> …
