PID using formula node, output problem (varying between 0 to the set point)

[Moonnight786]

Hello all;

I am trying to make a PID control in  LabVIEW. my main objective behind this is I need to set my Analog output value to the setpoint I want. (0-5v max) I tried to use LabVIEW paid toolkit but it didn't help me. so I write my own code in formula node, it's trying to set the output, but it's varying from 0 to the set point. anyone can look into my problem and help. my only job is to keep the Analog output voltage to desired set point using PID.

Please see the Attachments.

Hello,

 I am unsure on what you mean by formula node? Also, which toolkit were you using that did not work for you?

I recently made a very simple PID VI. The Error Factor is set point - process variable.

Thank you Brian J for your reply, I tried to use Labview PID toolkit,
