Hello Reynith,

I am not seeing any data to understand your issue, otherthan bunch of FP and BD images attached.

We cannot debug an image without VI, Make sure you understand your issue and ask appropriate questions.

I am sure my Signature statement Suits best for this post "If you can write the problem down clearly then the matter is half solved".

As a first step tell us where you got that "PI controller" subVI. This definitely does not look like anything that would ship with LabVIEW or any official driver from a reputable company (just look at the connector pain pane!

There is not control or diagram constant labeled "h", so we have absolutely no idea what's connected to where. Maybe you can look inside the subVI to guess what it does with it.

And yes, pictures of diagram that contain mostly express VIs and dynamic data are impossible to analyze because most information is hidden.
