Dear All Experts;

Maybe I had asked this quesiton before. But it is hard for me to explain technically.

For that reason I wanted to ask again and I hope someone could give valueble reason.

The graph taken from Commissioning of PID Compact and the graph taken from HMI is different.

when you look at the graph on commissionig the input value is like square wave. But in actually the input is not like this and it should be lineer.

Here attachment a screen taken from pid comapact commissioning view

and in the second post I attached a photo taken from HMI panel

Here the photo which I took from HMI panel...

it is the same application, but as you see the pid compact graph is different and the signal seems like square wave.

Dear Mr. Mister T.

I thank you for your valueable advice.

I will try to realize your suggesiton and give the information about the result.

Best regards...

Mert
